A tender low carb lemon poke cake baked in your slow cooker. This is the perfect sugar-free, grain-free dessert to welcome Spring!
So here we are, another instalment of the low carb slow cooker cake series. It’s been four months since my last slow cooker cake and it was high time to create another one. Now, I will be honest that this particular flavour would never have occurred to me if not for a suggestion by a reader. Lemon cake certainly occurred to me, but not lemon poke cake. In fact, poke cake was an altogether foreign concept for me until a few short years ago. I’d never heard of them and then suddenly they were everywhere. Every. Where. Well, everywhere on Pinterest, anyway. As with anything in Food Blogger Land, they seemingly came out of nowhere and overnight everyone and their dog was making them, photographing them and posting about them.
Still, I never really thought about making one until a reader emailed with her request. And not only was it for lemon poke cake, but more specifically for slow cooker lemon poke cake. Which presented its own set of challenges, I have to say. If you’ve never heard of poke cake, it is as the name suggests: you poke holes into your cake and then pour something gooey and delicious over it so it sinks down into the holes. Normally, such cakes are simply spread in a pan and baked in the oven, then poked and prodded and filled and frosted. And often it’s served right from the pan after that. But a deep slow cooker makes that a little more complicated and I didn’t want this to come out in messy pieces with the frosting smeared all over. So the ever useful parchment paper to the rescue for lifting the cooled, poked and filled cake out of the slow cooker, to be frosted on a serving platter.
My second challenge was deciding what to pour over the cake to fill the holes. Some research on lemon poke cake yielded two possibilities: lemon jello and lemon curd. As much as I love lemon curd, it’s a far sight more time consuming to make, so I opted for lemon jello. But of course, I wasn’t about to go buy the commercial sugar-free lemon jello, all chemical-laden as it is. No, no, no, that would simply not do. Making your own healthy Jello is easy enough, thankfully. And to make it stand out a little more in the cake, I added a few drops of yellow natural food colouring. Then a simple whipped cream frosting and there we had it: low carb slow cooker lemon poke cake.
There’s no reason you couldn’t do this in the oven too, although you might lose a little of that amazing tenderness that comes from baking in your slow cooker. I’d recommend a 9×13 well-greased pan at 325F. I am not sure how long it would take to cook, but start with 25 minutes and check on it every 5 minutes after that.
Slow Cooker Lemon Poke Cake
A tender low carb lemon poke cake baked in your slow cooker. This is the perfect sugar-free, grain-free dessert to welcome Spring!
Ingredients
Cake
- 3 cups almond flour
- 3/4 cup Swerve Sweetener
- 1/4 cup unflavored whey protein powder
- 2 tsp baking powder
- 1/4 tsp salt
- 4 large eggs, room temperature
- 1/2 cup unsweetened almond or cashew milk
- 1/2 cup butter, melted
- Zest of one lemon
- 2 tbsp lemon juice
- 1 tsp lemon extract
- 1/4 tsp liquid stevia extract
Sugar-Free Lemon Jello
- 1/4 cup fresh lemon juice
- 1 tbsp grassfed gelatin (Great Lakes orange can)
- 1 cup boiling water
- 3 tbsp powdered Swerve Sweetener
- 3 drops yellow vegetable-based food colouring (optional but helps boost yellow colour)
Frosting
- 1 cup whipping cream
- 1/4 cup powdered Swerve Sweetener
- 1/2 tsp vanilla extract.
Directions
Cake:
- Line a 6 quart slow cooker with parchment paper with enough parchment coming up the sides for easy removal. Grease parchment paper (I like to use Kelapo Coconut Oil spray).
- In a large bowl, whisk together the almond flour, sweetener, protein powder, baking powder, and salt. Beat in eggs, nut milk, butter, lemon zest, lemon juice, lemon extract and stevia extract until well combine.
- Pour batter into prepared slow cooker and cook on low for 2 1/2 to 3 hours. Let cool completely in the slow cooker, then take a skewer and poke all over about 1/2 an inch apart, twisting skewer to make holes.
Jello (make this while the cake is cooling):
- Comine lemon juice and grassfed gelatin in a bowl and let sit until thickened. Add boiling water, sweetener and yellow food colouring, if using and stir until sweetener and gelatin are completely dissolved. Let cool until beginning to thicken.
- Pour all over the top of the cake, letting jello sink down into the holes of the cake. Lift the ceramic insert out of the slow cooker and refrigerate 2 to 3 hours, to set.
- Using the edges of the parchment, lift the cake out gently and place on a serving platter (if you want to remove it from the parchment, place it on a flat surface and gently work a sharp knife underneath it, then use two large spatulas or flippers to move it to your serving platter).
Frosting:
- Beat whipping cream with sweetener and vanilla until stiff peaks form. Spread all over top and sides of cake.

Slow-cooker lemon poke cake-
Too many “weird” ingredients for a normal cook/kitchen. I would never go out to seek all of this stuff unless I needed it for severe health reasons.
Carolyn says
You do realize that this is a low carb food blog, right? And weird is only a matter of perspective. 🙂
Judith says
These are the ingredients in my cupboard. There’s no sugar or grain flour at all!
colleen says
hahaha…Funny how people view things so differently. There is nothing weird about this at all. These are normal, everyday ingredients in my home. We have no flour, sugar, jello etc. Everything is home made and “real”
Carolyn, you never cease to amaze me. I have made several of your recipes and love them all. Thank you for all your hard work
April says
OH MY ~ It looks wonderful! I made an oven baked almond flour poke cake for my daughter’s birthday. It was good, but this looks awesome. I will definitely try it again when I need a birthday cake. Nope not weird at all, for us low carbers, the ingredients are already on hand. 🙂 Thank you for doing this.
Stephanie says
Can’t wait to try this one! Your slow cooker chocolate cake is awesome!
Dita says
Carolyn, You have done it again! A lovely recipe with ingredients that all Low Carbers have on hand, no exotics. Thanks. One question: Can we use Slow Cooker Liners rather than the Parchment Paper??
Malainie says
Love all your recipes, Carolyn! This might be an option as a liner, too: http://www.amazon.com/Smart-Baker-Shark-Pre-cut-Parchment/dp/B00FW49GUE/ref=sr_1_3?s=home-garden&ie=UTF8&qid=1426691866&sr=1-3&keywords=parchment+paper+rounds+9+inch
Angela says
MMMMM this looks good. I just bought lemons today too so may have to give this a run soon. Speaking of cakes, have you tried to do a remake of angel food cake??? This is one cake I really miss and I have a divine high sugar/carb recipe that I still make for special occasions but I would like to see a healthier version if possible that still tastes good. Also, have you experimented with banana flour? I guess it’s the new paleo flour. I haven’t seen a lot of recipes using it yet but it’s supposed to be really healthy and an excellent source of resistant starch.
Susan says
When I first became low-carb, I found an Angel Food Cake recipe by Matthew Meade posted on the Chicago-Sun Times website. I just tried that link, and they appear to no longer have it on their website.
I’ve posted his recipe here: http://www.springvalley.org/Angel_Food_Cake_lowcarb.pdf
Now that I’ve been low-carb a while, all of the ingredients are familiar and stocked in my cupboard. I do recall (at the time I found it) that the ingredients seemed quite foreign. Funny the difference a year makes!
I haven’t tried it yet, but my daughter’s birthday is coming soon.
Angela says
Can you let me know how it was after you make it????
Stephanie KL says
Sorry, Susan, but I got an error message when clicking on the link saying that it could not be found.
Judith says
Now that we are in CA for much of the year, slow cooker cakes, etc are the way to go. There’s no unwanted heat in the house. In fact, I’m trying out some of your other recipes in the cooker. I love lemon and will mix this up this afternoon. Thanks.
Karen says
Um… not weird at all. These ingredients ARE our normal! And, I’m not tying to be snarky, but “severe health reasons”? How ’bout GREAT health reasons? Low carbing, typically, ensures lower blood sugar, lower cholesterol, increased energy, etc., etc. I will be making this cake SOON. It looks delish! Thank you, Carolyn.
Krickt says
My grandmother used to make poke cake, but she used the handle of a wooden or plastic stirring spoon to make the pokes. It made for serious amounts of “jello” in every slice. I think I’ll try this.
As to weird ingredients, the only thing I don’t have on hand is lemons, since I don’t keep citrus (high sugar) fruits on hand. But I can get them within a few minutes.
Who hunts down specialty food bloggers to complain about ingredients?
Geeze.

Sally says
Hi Carolyn,
I have all the ingredients on hand except the grass fed gelatin. Is there another gelatin or item I can use in its place ? I have been adding to my ingredients that I keep on hand – makes it easy to do your recipes and whip up a surprise for the family each week. Thanks, Sally
Carolyn says
You can use a package of Knox gelatin.
Judith says
I did it!! The flavor is fabulous. Perfect. My cake came out a little on the moist side, though. Next time I’ll have to reduce the liquid a touch or add a tsp or 2 of coconut flour. It did rise completely but is a bit like steamed pudding. This has the best lemon flavor of any lemon cake I’ve ever tasted. I used NOW beef gelatin which I purchased in 5# bag….no problem.
Leslie says
I can’t wait to make this! Do you think I can substitute egg white protein powder for the whey protein? Dairy allergies. I am wondering about the amount of extra egg in doing that.
Thank you for sharing your great recipes!
Carolyn says
I think egg white powder would be just fine.
sally says
Thanks for the response
heather says
How much fat is in it though, since that’s a lot of almonds to make 3 cups of flour?
Carolyn says
Lots and lots of wonderful healthy fats. You can see the nutritional counts at the bottom of the recipe.
Alison says
I love slow cooker cakes!!! I can’t wait to try this one! Can I use Jell-O brand sugar free lemon pudding instead of making from scratch? 🙂
Carolyn says
Sure, although you may only need half of it.
Sarah G says
I asked the almost 5 year old if he wanted this lemon cake for his birthday. He said, “Wif chocolate frostin”. Would I just add cocoa powder and take out the vanilla exctract?
Carolyn says
Hmmm. No, I don’t think just adding cocoa powder would work, it might make it way to thick and clumpy. Try this for a chocolate frosting (you may need to do 1.5 to 2 times the recipe): https://alldayidreamaboutfood.com/2010/07/coconut-flour-cupcakes-with-chocolate-buttercream-low-carb-and-gluten-free.html
Sarah G says
Whoa, that looks delicious! Are the stevia drops the only sweetener needed? Whenever I’ve used stevia alone with chocolate it’s so bitter. Maybe the whipped cream keeps that from happening?
Sarah G says
I just read the post and you say it’s not bitter at all. Yay!!
Carolyn says
The cream cheese helps because it gives the frosting stability and you don’t need a lot of the stevia drops. But if you want to use powdered Swerve, you can use that too. I’d use at least 1/4 cup if you double the frosting recipe.
Sarah G says
extract, that is!
Amy says
Carolyn, this looks fantastic! Easter always makes me think of lemon cake. I’m so glad you took the time to develop this recipe. I’ll definitely be trying it!
Sandy says
I’ve had my eye on this recipe since you posted it and am finally making it! It is cooling right now and smells divine! My T1D hubby, the reason we started this low carb adventure, doesn’t like lemon, but I couldn’t resist making this. I made him another treat and figured that’s just more cake for the kids and me! Thanks for sharing! I love the slow cooker cakes– yum!
Ginger says
Could you bake this in an oven? My 6 qt. slow cooker is too hot to bake cakes in, the edges overcook quickly.
Carolyn says
Yes, I think I mentioned at the bottom of the post doing it in an oven at 325F in 9×13, but I don’t know how long it would take to cook (probably at least 25 minutes)
Jenny says
After laughing my head off from the 1st (ridiculous/ignorant) comment. . I went to my cupboard & took all the ingredients out to put this wonderful cake together! Lol! Thanks Carolyn for this awesome recipe! We all appreciate your hard work coming up with these delicious recipes so we can live a healthy successful low carb life! I don’t think I could do it without your genius-ness cooking/baking skills! 😀
Susan says
Made this yesterday, but too late to taste test. My daughter and I had it for breakfast. Yum! (The aroma while baking was heavenly. All family members wanted to know when it would be done.)
Helen says
Hi Carolyn, For the whipping cream, do you use heavy whipping cream? Since my daughter was diagnosed T1D this year we have been told to do all low fat things for her, but low fat whipping cream isnt really working for us. I’ve done a couple recipes in the last few weeks with regular heavy whipping cream and I didn’t see her spike. I just wanted to get your thoughts on the low fat vs. regular fat.
Thanks so much!
Carolyn says
Full fat, heavy whipping cream. I don’t do anything low fat and I don’t believe it’s healthy for anyone to eat low fat because that usually means more carbs (sugar) to fill the gaps. I am not a doctor or a medical professional, so please do your own research but I think you should investigate the low carb high fat diet for your daughter as the healthier option. Please check out Dr. Bernstein’s Diabetes Solution and you can get great support and info on this Facebook group as well: https://www.facebook.com/groups/660633730675058/
Helen says
Thank you so much for getting back to me on that and sharing the link for support! I am really glad to hear that full fat is what you are doing. I will continue to move forward in this direction and research since her levels are staring to speak for itself with low carb and full fat. I feel like we are in the right track. Now off to find more yummy food on your site!
Helen
Carolyn says
Good luck, Helen. I am sure you know this but she should eat to her meter. Keep a close eye on her food and her levels and then you will figure out what works for her.
Ashley B says
This looks wonderful! I was wondering if you could use the THM lemon pudding as the Jello? Thoughts?
Carolyn says
I can’t see why not!
Jennifer says
I LOVE this cake! I made it for Easter dessert. I cooked it Saturday and planned to do the rest on Sunday. I totally forgot and ran out of time so I skipped the gelatin part and added about 1/4 tsp lemon extract to the whipping cream. Everyone loved it! Thank you so much for all your recipes! You’ll just never know what a difference your recipes make to me and my family!
Angelina says
I agree with everyone that this cake is fantastic. I am slow cooker-less so I’ve made it twice in the oven at 325….only takes about 15 minutes to bake. When making it the first time I tried the bit of the cake before pouring the gelatin over it (impatience to taste the lemony deliciousness) and was surprised at how good it tasted on its own. The recipe was so quick, easy and tasty that I soon wanted to make it again but could not find sugar free jello (yes I phoned it in with the gelatin…..) so I decided to make the cake without it. I simply added 1/4 cup more sweetener, doubled the zest and extract (to get the sweetness and lemon flavor that would have come from the gelatin soak) and voila! Turned out tender, moist and delicious! This will be my go-to lemon cake recipe from now on….thanks Carolyn!
Angela says
what size pan did you use?
Angelina says
Angela, I used a standard springform pan lined with parchment paper.
stephanie says
We don’t care about the poking and the filling, so if we eliminate that part will it still come out moist or do you need that filling as part of the flavors?
Carolyn says
It’s still really great on its own!
Susan says
Perfect summer cake. Made it last night and added a few fresh strawberries and blueberries. It tasted like a lemony strawberry shortcake.
Next time, I plan to try your lemon curd in lieu of the jello. I remember the poke cakes I had as a kid were yellow cake with chocolate pudding poked in it. Now I’m thinking I can make this as a yellow cake with vanilla in it instead of lemon and use your death by chocolate ice cream custard base as the pudding. I’ll let you know how it turns out.
Carolyn says
Thanks!
Marie says
This looks fabulous and so easy. Saving the recipe and would like to try it in a few weeks. Thank you so much. My crock pot is only 2.5 quart. Do you think that I can just use half of the recipe?
Carolyn says
Yes, I think halving the recipe should work just fine.
Marie says
Great. Thank you so much. Can’t wait 🙂
Naomi L says
Looks fabulous & I LOVE lemon! Is there something you could substitute for the wheyy the only thing I have on hand is strawberry. I do have some psyllium powder though, would that work and how much would I need to use? Also can I substitute Splenda for the swerve and what amounts would use?
Thanks for the great recipes!!!
Carolyn says
Oh, yeah, don’t add the strawberry whey here. You can forego it altogether but the cake may not rise quite as much. Don’t add psyllium, it will get too gummy. Not sure about the Splenda as I don’t use it but Swerve measure like sugar so I am sure you can figure out how much Splenda to use from how much they say is equivalent to sugar.
Annette Mahoney says
So I made this cake for a friends daughters 7th birthday.Since finding out she cant have gluten she has not been able to have a birthday cake. She was so over the moon with happiness with it. The whole family loved this. Carolyn thank you for coming up with such a healthy and delicous cake. I did bake it in the over for about 33 min in my oven. You helped make a little girl happy……
Carolyn says
Wonderful, I am glad to hear it! Celiacs, diabetics and everyone deserves cake on their birthday!
