Moist cinnamon apple coffee cake drizzled with homemade low carb caramel sauce. Everything you love about fall in one recipe!
Okay, so today is supposed to be a Makeover Monday post but already I am getting off track and straying from the schedule. And here we are, only the second week in! Welcome to the world of Carolyn, disorganized blogger and hater of all things routine. That girl, she can’t stick to a schedule if her life depended on it! Although, truth be told, this one is due to circumstances beyond my control. I have a great makeover recipe for you, but because it is part of larger campaign, it’s being pushed to tomorrow or Wednesday. And so, Makeover Monday becomes Makeover Tuesday or Wednesday. Doesn’t quite have the same ring to it, does it?
However, to appease you, I offer up this delectable low carb Caramel Apple Coffee Cake. Apple season is in full swing here in New England, and apple-picking is one of my favourite things about fall. I have always loved apples and back in the day when I had a fully working pancreas, I ate at least one a day. Apples are surprisingly high carb, so I now limit myself to half an apple here aor there. Or I eat one before I go for a run or work out, since I will burn the sugars up quickly anyway. But they still rank among my favourite fruits and there are usually plenty of apples in our fruit drawer. They’re infinitely portable and great for kids’ lunches, since they won’t smoosh like softer fruit.
Even if I couldn’t eat apples at all, I’d probably still go apple-picking every fall. It’s a tradition in these parts and it was when I was growing up in Toronto too. Getting out of the city and into the apple orchards on a warm, sunny fall day makes the world seem like a friendlier place. And those sun-warmed apples picked right off the tree…truth be told, I’d run a whole marathon, just to be able to eat one. That crisp flesh, crunching under your teeth, releasing the tangy juice and sweetness onto your tongue. Yep, that’s worth some serious mileage in my books!
This recipe idea has been floating around in my brain ever since the kids went back to school, and I could hardly wait until we went apple-picking to make it. I knew I’d have to go light on the actual apple in the cake, to keep the carb count down. But I helped the flavour along a bit with some apple flavouring in the cake batter. Then I swirled in some homemade low carb caramel sauce into the batter, and sprinkled the top with a cinnamon crumb mixture halfway through baking. And then a drizzle of some more low carb caramel sauce to finish it off.
Now that’s what I love about fall!

Katharine says
This is like my dream dessert!! Caramel….apple…..I’m drooling!
Loretta Spann says
I cooked this cake yesterday and it is delicious! I did make a few changes as I didn’t have Whey, Apple flavoring, and out of Xanthum gum. I used Collagen instead of whey, vanilla flavoring, and grass-fed gelatin instead of Xanthum gum in making caramel sauce. I used a few drops of Maple syrup for color and flavor. I also put walnuts and a few raisins in the cake! We don’t have a weight problem just on a low carb diet because wed have low blood sugar if we don’t stay on low carb! Thank you so much for this delicious recipe!
Kathleen says
Do you think it would taste good without the apple extract?
Carolyn says
Absolutely! Sub in 1 tsp vanilla extract instead.
Alexandra says
I’m trying this weekend with maple extract…. really excited!
Kelli says
Is there a reason for combining xylitol and swerve in the caramel sauce? I love to use xylitol but our little doggies get into our trash and after a couple of small panics I decided to switch to eyrithritol instead. O.O
Carolyn says
erythritol doesn’t stay in solution and your caramel sauce will re-crystallize and harden. That said, it will still taste really good!
Kelli says
Awesome, I think I’ll give it a go with all eyrithritol and make them into muffins as my hubby will most likely reheat when he eats them :). His fave breakfast used to be these rich pumpkin and butterscotch muffins that are definitely not low carb or sugar free, I think this will be a great substitute !!
Carolyn says
I contemplated making these muffins instead of cake, so I think they would work well. The bake time will be less, of course.
Alexandra says
First of all, your blog is absolutely amazing and has really helped me find recipes that I can make to accomodate the rest of my family’s standard diet. They love all the new dishes I’m making for them and I get to enjoy them too. Also, I didn’t know you grew up in Toronto! The apples are absolutely huge here, and when I went apple picking last weekend I came home with over 25 lbs of apples and no idea how to cook them into something low carb. Thank you so much for this recipe, it’s a life saver!!
Carolyn says
That’s a LOT of apples. I like to do a big canning of apple sauce for my kids when I have that many apples.
Jeanette says
What a beautiful fall cake Carolyn – sounds like such a warm comforting treat!
Eat Good 4 Life says
This looks superb. I will share this one on my FB page 🙂
Carolyn says
Thank you!
Melanee says
Beautiful job on this coffee cake, Carolyn!
Darlene says
I’ve not seen Swerve in our neck of the woods yet. What would you substitute in place of it?
Carolyn says
Any brand of erythritol should work.
Kim - Liv Life says
My husband is not a coffee cake fan… but me?? I eat both of our shares!! And add apple to it? A total hit!! LOVE this recipe!!!
[email protected] says
WHOA!! What a cake! And that caramel drizzle…I need this immediately!
Sue in CA says
Wow this sounds just delish! Was hoping to make it for family visiting soon but they have nut allergies and this would be deadly for them … and I don’t mean on the hips.
I’ll have to make it for me and hubby, sigh, so sad, too bad … I’ll have to freeze most of it, LOL for continued enjoyment.
Liz @ The Lemon Bowl says
This is such a beautiful cake!!
Robin Morelock says
I’ve recently discovered your website and have had very good success with your recipes. I’m wondering if there might be a good substitute for the whey powder. It’s not easily obtained where I live. I’ve looked on the Internet and have found only large quantities to order. Plus, I don’t really enjoy the taste. Any suggestions? Thanks so much!
Carolyn says
Hi Robin…you won’t get any taste of whey if you use the unflavoured variety. But if you can’t get a hold of it, can you get powdered egg whites?
Robin Morelock says
Thanks so much for your speedy response. Yes, I use powdered egg whites all the time! Protein for protein, right? Would I use the same amount?
Carolyn says
I think the same amount would work. I can’t be positive but give it a try!
Deborah says
Robin, you can order unflavored whey protein powder from iherb.com – they deliver all over the world. I ordered a fairly small canister, wasn’t expensive, got here (Israel) in about a month. And shipping is cheap, too – I pay $4 for any package that is under 4lbs in weight.
Robin Morelock says
Thanks Deborah! I’ll definitely check that out.
Luana says
Carolyn, you never cease to amaze me with your wonderful recipes and breathtaking photos! This looks like it would be a wonderful addition at any Thanksgiving dessert table.
Medeja says
That caramel makes it look even more tempting! 🙂
Sylvie @ Gourmande in the Kitchen says
Now that’s the kind of cake I want a big slice of when the weather gets cooler with a nice cup of tea.
V says
I love apples as well and I was keeping myself from eating a lot. With my CGM, I realized that a 4oz tart apple such as a Macintosh is not more than 6-7g each (which is far from the nutrition fact). I can totally eat 1 or 2 per day without even using insulin (I’m type 1). Your cake is lovely. Now I need to bake…
Carolyn says
We like to pick the small ones when we go apple picking, so that I can eat a “whole” apple. But the ones you find in the grocery store are typically much larger than 4 oz!
Alison @ Ingredients, Inc. says
fabulous Carolyn! As always!
Linda says
In the caramel sauce, can you use all Swerve and not Xylitol? I don’t use Xylitol, so I am trying to substitute something else. Thanks for the awesome recipe!
Carolyn says
Yes, but your caramel sauce will harden a lot more. It will still taste good though!
Nami | Just One Cookbook says
I love good coffee cakes that are moist. I finally found this breakfast place that serves excellent blueberry coffee cake (and I’m going this Fri for brunch!). They started to serve apple coffee cake that I had been curious. Now that I saw yours I’m even more excited to taste it. Your coffee cake looks really delicious, Carolyn! I’ll need to save this recipe so that I can make my own (it’s about time!). 🙂
Deborah says
This looks divine. Is there any way I can make the caramel sauce dairy free? I can use palm shortening in place of butter, but I don’t know what I could use instead of the whipping cream… do you think coconut cream would work, in terms of consistency and flavour? Thanks!
Carolyn says
I think it’s worth a try with coconut milk!
Deborah says
then maybe i will! 🙂 i’ll let you know how it turns out when i make it…
Sommer @ ASpicyPerspective says
Gorgeous cake, Carolyn! Love that it’s on the lighter side! 🙂
Sandra says
Thank you for telling us all about your being a diabetic. My son 29, was diagonosed a year ago (type 1). He is struggling with his diet and I am concerned for him. He is not a big sweet eater but loves pasta, bread, and crackers. I love getting your recipes via email. Thank you again for the yummy and eye appealing photos.
Carolyn says
I understand for your son, it’s a tough diagnosis and can really through you. And in his case, with Type 1, it’s so imperative to figure out the food and insulin levels.
Roni says
Looks wonderful! There are only two of us, so it looks like I’ll be making muffins c this recipe. Wonder if the Carmel sauce would freeze in ice cube trays so I could use when I thaw out a couple of frozen muffins for us? Also, I would like to thank you for setting up your recipe print page to be able to print two sides; this certainly helps to save paper!
Carolyn says
The caramel sauce will harden a lot in the freezer but it’s worth a try!
Vicki Bensinger says
Your Caramel Apple cake is beautiful. That bit of caramel dripping off the cake had me drooling. Great recipe – SAVED!
Carolyn says
Thank you!
nichole says
I am allergic to dairy products, and I am wondering about a sub for the whey protein. Can I sub coconut flour? It is hard to get powdered egg whites here.
Carolyn says
Coconut flour won’t help you, because it contains no protein (the protein helps things rise properly). How about this? Add another 1/4 cup of almond flour and one extra egg. The consistency will be a bit different but it should still be good.
Robin Morelock says
Nichole, I order powdered egg whites from honeyvillegrain.com . They also have fantastic almond flour at a good price.
Shyla says
I’m wondering what kind of stevia you used. I have the old formula nunaturals which is very concentrated. I usually have to use much less than the recipe calls for if the original recipe used the kind that has filler.
Carolyn says
This time, I think I was using SweetLeaf. I just ordered some NuNaturals through amazon!
jillian says
this sounds awesome…i like the almond flour but must use coconut sweeteners….so here is the question..since i am ok with some carbs from fruit would it change the cake to add a bit more apples? thanks
Carolyn says
The apples do make it moister so be careful not to add too much. Almond flour is moist enough as it is, I don’t want you to end up with a soggy cake!
Pamela says
This cake has definitely put me and my tastebuds in the mood for all things fall even though the weather is quite cooperating yet! This looks scrumptious; especially that lovely molten caramel. I was wondering whether you thought chayote might work in place of or combined with the apples to lower the carb count even further? I’ve made a chayote “apple” crisp before that tasted like the real thing (it’s a sponge to soak up the spices & flavoring) but I don’t know how it would work in a cake. At any rate, I’m definitely making this. Thanks!
Carolyn says
Feel free to use chayote, but honestly, the carb count on this cake is so low, I don’t know that it would help that much!
Buttoni says
My this looks scrumptious, Carolyn. I’ll have to try it when I’m on sweets again. Just lovely, and apple cake is my fav cake after Black Forest.
Mary Kate says
Great looking recipe! 🙂 I tried to make a caramel sauce today and I was heating splenda over medium heat and suddenly my pot broke from underneath (it split open) and I heard a pop noise. Some sort of reaction to the splenda being heated I guess. This caramel sauce looks good though! Can you think of why this happened? I don’t know much about working with these types of sweeteners in baking!
Robin Morelock says
I’ve recently seen a product from Honeyville called Hi maize resistant starch. Have you had any experience with this product?
Carolyn says
I’ve heard of it but I haven’t ever tried it myself.
Carolyn says
I have no idea, I don’t use Splenda at all. Erythritol is not an artificial sweetener so it works very differently from Splenda.
[email protected] says
That is one beautiful cake!! I looooove the cinnamon crumb!
I’m just as bad… can’t stick to a schedule for the life of me.
Chung-Ah | Damn Delicious says
The caramel sauce dripping down the sides definitely makes up for it! 🙂
Dina says
I have to try this. I love that you used almond flour. it looks so good.
caree says
As far as the sweeteners, I just have Splenda and Truvia at home, and I’m not sure if I could find the other ones you have listed without having to order online- I want to make this recipe this weekend; I’m impatient! I know you don’t use Splenda, but do you think I could use what I have? Why the use of 3 different sweeteners anyway? Thanks!
Carolyn says
Truvia is erythritol so you could try to caramelize that, but it will end up hardening once on the cake. It won’t be bad, though, just not a liquidy glaze. Every sweetener has its advantages and disadvantages and I think they work best in combination.
Melanie says
Well Carolyn, I think you outdid yourself with this one. I made it for a fall themed baby shower I was hosting and it was incredible! This is going to be a staple for holiday breakfasts at our house. Thank you so much for yet another wonderful recipe!
Carolyn says
So glad to hear it!
Elaine says
I made this over the weekend and it is absolutely amazing! I first thot one apple would not be enough but it was. Since my hubby is diabetic he didn’t need more than that. What a blessing you are. I had given up cooking fun stuff but not anymore. Thank you so much. Mine even looked just like your picture!
Carolyn says
Wonderful, Elaine, so glad to hear it.
Moe says
My daughter was in from college this weekend and I made this as a treat – she deemed the caramel sauce “better than caramel!” It was a big hit, just as your recipes I have tried are. Thanks! You inspire me to keep on baking AND keep my carb count down.
chanin says
Maybe you answered this and I missed it. Can you just use swerve in the caramel sauce? I don’t have xylitol? This looks delicious!
Carolyn says
You can, but just be aware that it will harden a lot as it cools. It’s just a thing with erythritol, it won’t stay in solution.
Shaina says
That is one gorgeous coffee cake.
Barbara says
My family is having an early Thanksgiving dinner this Saturday, since family members will be vacationing over the holidays and we won’t all be together. I’m going to make this for dessert and my thought is to make on Friday, after I get home from work. Do you think I can leave it out on the counter until our early dinner the next day? Or should it be refridgerated?
Carolyn says
One day on the counter would be fine. Any more than that, and you should refrigerate.
Jennifer says
Carolyn, I used this recipe to make an upside-down cake — I just put sliced apples in the pan, covered with caramel sauce, and then poured in the cake batter. The cake performed beautifully, being substantial enough to support the topping, and flexible enough to absorb the apple juices as it was cooking.
Carolyn says
Wonderful. your version sounds delicious!
Brandi says
Do you think I could use coconut flour instead of almond here? And, of so, how muh less coconut flour would I use?
Carolyn says
No, this cake recipe is based on almond flour so you really should find a cake recipe that is based on coconut flour instead. I have a vanilla cupcake recipe that might work. https://alldayidreamaboutfood.com/2013/11/vanilla-bean-coconut-flour-cupcakes-and-teaching-children-about-kindness.html
Kate says
Could I leave out the protein powder or do have a substitute you would recommend? This looks so amazing! Thank you for any input:)
Carolyn says
In the absence of gluten, protein helps the cake rise properly. But you can use any sort of powdered protein…hemp, soy, even powdered egg whites.
Cathy says
Hi,
Just wanted to let you know I am sharing your wonderful recipe tomorrow in my Gluten-Free Recipe RoundUp with a link back to your original post!
Have a terrific weekend!
Cathy from APeekIntoMyParadise.com
Jennifer says
Do you know if Swerve and Truvia can be used interchangeably? I’ve never bought Swerve before…
Carolyn says
Truvia doesn’t caramelize quite as well but you can certainly use it. Your end product will likely be paler in colour but still tasty.
Scarlett says
I know that a lot of people have asked about using erythritol/only swerve for the caramel sauce and you said it’ll re-crystalize. But do you think I could use only powdered swerve and make it more like a caramel glaze?
Your blog is hands down my favorite website. Thank you for creating/adapting such amazing recipes!
Carolyn says
You can use powdered and it will be good…but it will still re-crystallize more than with the Swerve/xylitol combo. Pour it over when it’s hot, though and it will be delicious!
noreen says
Do you have an info sheet of all the different sweetner you use in your baking, including brand names, and how to use them effectively. I am so confused, swerve, xytiol, erythitoil, liquid, etc. Until I started this way of eating I only used sweet n low to sweetened my ice tea! I’m no a big added sugar person but I do bake tons and I don’t ice very sweet desserts, so I always adjust sweetness when sugar doesn’t matter. Thanks in advance.
Carolyn says
I don’t have such an info sheet, but I really should make them. However, I can tell my that my preferences are for Swerve (which is mostly erythritol) with a touch of liquid stevia extract (NuNaturals brand). I only use xylitol when I need a caramel sauce to stay liquid. Hope that helps for now!
Marcille says
This is the first THM thing that my husband has said that is good–you can make this again. He is very supportive. Just hasn’t been on board for eating the food.
Thank you!
Carolyn says
Wonderful compliment, thank you!
Lee says
I don’t use almond milk regularly and it kills me to open a container just for the little bit I’m going to use in a recipe because the rest of it will go to waste. I always have yogurt and whole milk on hand. Can I sub either of those for the almond milk?
Carolyn says
Yes, go ahead and use whole milk. Or a combo of whole milk and water.
nicole thomas says
You are an incredible artist Carolyn, truly gifted. May God bless your move to my beloved pacific northwest! I pray that your family will make many memories, beloved traditions and lifelong friends there!! I’m jealous, I moved to the south , and though memphis is home now I find myself missing the more pronounced fall time….. this amazingly yummy cake will help though, reminds me of apple picking time from my childhood!!! again, thank you for all you do, your husband must be very proud of his creative wife!!
Emma says
Going to make this soon! I assume ideal would work as xylitol for the caramel sauce. (it has some maltodextrin added, mostly xylitol)
After reading comments I presume 4oz is what you’re counting carbs on for the apple? “medium”?
Carolyn says
Yes, Ideal should work. “Medium” apple for whatever the standard is on the USDA nutritional website. Can’t remember what size that is.
Emma says
thanks Carolyn! For those wondering, USDA says 1 medium with skin is 182g, or 6.5 oz.
Carolyn says
Thanks for finding that out! 🙂
Amy S says
Just made this cake and ate it for the first time. DE-LISH-USH!!!! It was so good, and so moist and so apple-y. Going to try as muffins/cupcakes next time for easier freezing. You are a genius! Good luck on your move. I think you’ll like it here in OR, lots of runners and health conscious folks, in addition to LOTS of foodies. Hope to meet you someday!
Carolyn says
I know I will love Oregon…it’s just the getting there that’s the tough part right now!
Sue says
This recipe sounds and looks amazing! I love caramel and apples. Your site is by far my favorite (or should I spell it favourite – I am a fellow Canadian living in California and I smile every time I read your blog when I see the Canadian spellings). You have incredible recipes and great tips for LC baking. I am new to this lifestyle and couldn’t live without sites like yours. Thanks for all you do!
Carolyn says
Thanks, Sue! I have my spell check set so that it allows that U in favourite and flavour.
Emma says
wow. just wow. I was worried the caramel sauce would recrystallize as I’ve had bad luck with LC caramels in the past – I used 1/2 swerve and 1/2 tagatose and added a drop of glycerin just in case – perfection. just had to heat it to drizzle!
This recipe was fool-proof. my medium apple was about 150g and the whole thing cooked up nicely but took about 25 minutes longer in my bosch convection oven (on standard bake setting, though) Everything turned out and the apple flavor, sweetness, and texture were all SPOT ON. HOORAY FOR CAROLYN’S GREAT INSTRUCTIONS & RECIPES!
My mom with a november birthday loved it. Not low-carber, either 🙂
Carolyn says
Wonderful to hear, Emma!
Emma says
I might add, my mother thought whipped cream was a necessary compliment 😉 can’t say no to that, myself!
samantha says
i just made this in a 9×13 pan and it came out yummy!! SO moist and good! i had to make a few subs and it worked out perfectly, here is what i did [incase anyone is wondering :p]
I only had 2.5 cups of almond flour, so i used flax meal for the other .5 cups, its all i had and it turned out great!
i didnt have apples or apple flavor, but i really wanted apple so i used apple spice tea i had, i brewed like 6 bags in a half cup of hot water for a few mins and it was really strong, i used that in place of almond milk and it tastes appley and smells like apple cinnamon!!
i had to add a little almond milk because the batter was SO thick, maybe the flax? either way it turned out good, i also used maple flavoring because i wanted to see how it tasted lol. very yummy 🙂
the caramel sauce was not a success, it did taste very good but i did not have xylitol so i just left it out and it got hard fast and impossible to drizzle so it was clumped up all over the cake, and when it hardened it was crunchy, so i made a basic glaze from butter almond milk and powdered swerve.
so all in all it is very yummy and definitely hits the spot with a cup of hot coffee!! 🙂 thank you!!
samantha says
oh and thanks for being so detailed! the caramel did smoke a lot! i was like oh no what did i do wrong!! then i read your instructions again, haha!
Patricia Bell says
I love your recipes but they all use some type of sweetener that contains xylitol or eurythitol (sp). I can’t use any type of sweetener that ends in “ol” . It makes me miserable sick. Sorbitol and manitol are the worst for me and it is the sweetener used in sugar-free candy. I use Truvia or Stevia. Can I use these instead in your recipes?
Carolyn says
If you use Truvia then you ARE using erythritol! Check the ingredients. So clearly, erythritol is not an issue for you. This is common, all the sugar alcohols give people GI distress EXCEPT for erythritol. So yes…you can use Truvia in my recipes but it is sweeter than Swerve so you will need to cut back on the amounts some.
Christy says
This is a very beautiful cake. I want to make it, but I’m strict ketogenic. I can use apple flavoring, but no apples. I know apples take up a large amount of room in the cake. What can I replace it with? And instead of the whey protein, will egg white protein work? Thank you much-Christy
Carolyn says
They don’t take up a large amount of room and leaving them out won’t affect the consistency. And egg white protein should be fine.
Erica says
Which do you prefer…this caramel sauce or your stand alone with molasses? I want to keep carbs low but my mom gave me a bag a very small (2.5-4oz) apples and I’m dying to have some. I saw the molasses recipe obviously had higher carbs but didn’t know if you felt it had better flavor/texture?
I’m afraid I’m probably getting too much fat for my probably moderate carb diet but trying to do this less stressful.
Carolyn says
I like the one that has a little molasses because the flavour is more true to caramel. If you just add even 2 tsp of molasses, the carbs aren’t much higher (maybe 1 extra gram per serving)
Felicity says
I’m about to make this. I was wondering whether there’s any reason why not to substitute your “The Best Low Carb Caramel Sauce” recipe for the one above? I am out of xylitol, and I know for a fact that TBLCCS works perfectly for me :). Thanks!
Carolyn says
Absolutely. I created this recipe before I perfected my caramel sauce so that’s why it doesn’t have it.
jean s says
Can you substitute 1/2 and 1/2 for the almond milk in your recipes?
Carolyn says
It adds more carbs. Try just replacing with water.
Dee says
Made this cake and it is wonderful. But with just 2 of us in the house, and I do not allow myself keto desserts everyday, can this be frozen? Thank you
Dana Duell says
What apple extract do you use, having a hard time finding one?
Thank you
