The classic chocolate Texas Sheet Cake gets a low carb, grain-free makeover. It’s a wonderful keto dessert for any time of year.
The creation of this recipe was a foregone conclusion. Pre-ordained. Written in the stars. Fate, destiny, kismet. It was an absolute inevitability. From the moment I published my low carb Peanut Butter Sheet Cake, I had readers requesting one of the traditional chocolate variety. Texas sheet cake seems to speak to something deep within the collective American psyche. Whether you are from Texas or not, it would appear. I got requests from all over the country, so it’s not as geographically limited as the name might suggest. It’s a well loved American classic and I simply can’t argue with that.
However, it’s hard to stay true to the classic when working with a completely different set of ingredients for a whole different way of eating. But this non-Texan, non-American resident alien did her best. She researched Texas sheet cake recipes for several days before even attempting to de-carbify this iconic dessert.
See, with the peanut butter version, I was straying far enough from the original concept to just do what I wanted with it, tradition be damned. Basically, it was a delicious grain-free peanut butter cake with a delicious sugar-free peanut butter frosting. But if I was going to attempt a real Texas sheet cake, I wanted it to be as close to the original as possible, and yet still without gluten or sugar. Tricky, that! I could easily have just relied on any one of my low carb chocolate cake recipes and then simply spread it with chocolate frosting, sprinkled it with pecans, and called it done.
Instead, I tried to take some main tenets from the traditional recipes and apply them to my low carb ingredients. Such as bringing the butter, water, and cocoa powder to a boil before adding it to the flour mixture for the cake, an unusual step that I don’t do in any other cake recipes. And also to stay true to the original, I poured the warm frosting over the warm cake, instead of letting it cool as I would any other cake. This makes something of a marriage between the frosting and the cake so that the cake is extra moist. Again, not something I would do with any other cake recipe.
The final result? Oh, kids, do you even need to ask? From Anchorage to Miami and everywhere in between, low carb dieters can now enjoy real Texas sheet cake. Maybe even some of my fellow Canucks will give it a go!

Hi Carolyn,
I would really like to make this cake, but was wondering if egg white protein would work? If so, should I use the same amount?
thanks for all your great recipes!!!
I really love them!
Yes, it should work in the same amount.
Thank you! Will give it a try!
This looks amazing!!! Thank you, Carolyn, for all your time and effort to bring us so many fantastic recipes. Tell me – is the Swerve in the cake part powdered or granular? I can’t wait to make this!!
You are my hero…this is a family favorite that we have done without for far too long
Us too! I’m so excited to try this recipe.
I’ve been looking for this for a while. Thanks so much!!
How do you think this would be as a cupcake… I sometimes have better control with servings if i do cupcakes 🙂
Well it obviously wouldn’t be a sheet cake then, but it should work. I’d make 20 low cupcakes with it (i.e. not filling the cupcake cavities very full…probably no more than halfway).
Granular or powdered Swerve in the cake batter? Thanks!
When I just say “Swerve”, I mean the granular because that’s standard.
Gotcha – I’ll keep that in mind next time. Thanks!
Why is it that every recipe that you come up with my first reaction is to make it immediately? I don’t care if it’s midnight or six in the morning. So many delish recipes, so little time. This is coming out of my oven this weekend.
Thank you, thank you, thank you!!! I’ve been waiting for this for so long! 🙂 Can’t wait to hear it.
Try it, not hear it.
#GetInMyBelly !! =))
And, I have all the ingredients! Woohoo!
What can be used in place of whey thanks
When I saw this I knew I had to make it. Then after looking at how easy it was I just ran into the kitchen. Well it is as I expected just so so delish. I happen to have a little coffee left in my pot so I used the coffee for the water and it gave it a little coffee flavor which I love with chocolate. My whole family was delighted with dessert tonight and will be for the few days. Thank You Carolyn again for making my family and I very happy!
So glad you like it!
This recipe looks so amazing! I’m just starting a maintenance on low-carb and can start adding things back. Almond flour……so expensive. Do you have a source online where you can buy it cheaper?
You can get a 3lb pound bag of honeyville at Costco for around $20. Best price I’ve found so far!
Thank you AGAIN for making me forget I’m diabetic! This looked so easy to make and it was. I didn’t have Swerve so I used my own sweeteners, including a bit of Splenda, I know I know but who cares, this is so amazing. Thanks to you I can have my dessert and eat it too 🙂 You are wonderful!
I am always happy to help people forget that they are diabetic. 🙂
I am really nervous to try this as every low carb chocolate brownie/cake recipe I have tried has turned out dry as dust & ingredients are expensive in my area. My husband and I have been Keto for 8 months but he is really missing his chocolate treats. I love your website and have tried many recipes – your Salted Carmel Cheesecake bars were awesome! But I really need a good moist chocolate cake desert – will this be it?
Read the reviews! So far so good. One question…what almond flour are you using? That might be your problem.
Several readers on Facebook have made it and loved it so far, so I say…give it a go! https://www.facebook.com/AllDayIDreamAboutFood/photos/a.295379530489443.84722.157146680979396/1285874208106632/?type=3&theater
I use Bob’s Red Mill and have tried the finer grind as well. Still the same results. Very dry. Perhaps will give this one a try. Thanks.
In a cake like this, you don’t want Bob’s (although they are coming out with a very fine almond flour soon!). You want Honeyville.
The Peanut Butter Texas Sheet Cake was a huge hit with friends who don’t restrict carbs and sugar. I’ve been waiting for this one!
Hope you love it!
Just made this recipe and it is perfection! You’ve made me a happy woman!
Yay!
Cake is great. I combined your two recipes. Made the chocolate cake and used the peanut butter frosting from the other sheet cake.
Thank you so much.
My stomach can’t handle almond flour. Is there anyway I can sub it with something?
How about sunflower seed flour?
I haven’t heard of sunflower seed flower I will check it out. thank you.
Sunflower seed flour (like pumkinseed flour and hempseed flour) is a very dry flour. It will absolutely change the texture of the cake. Especially when used in the same ratio as the almond flour. You can add this flours to almond flour or so, but I would not use them as a replacement.
Oeps, posted to soon.
I wanted to ask Carolyn what her thoughts are on this?
Sunflower seed flour, the kind that is simply ground sunflower seeds, is not drier at all. Perhaps you’ve used one that has been defatted? Because I replace them cup for cup all the time without issue, except for the turning green issue (which can be fixed with the addition of a little acid like lemon juice). See my video here on making your own sunflower seed flour: https://alldayidreamaboutfood.com/2015/12/how-to-make-your-own-sunflower-seed-flour.html
You can even make your own, although the purchased variety is a little finer. It does react with baking powder and can turn things green but if you’re making a chocolate cake, you can’t see the green. Weird but true! Here’s how to make your own: https://alldayidreamaboutfood.com/2015/12/how-to-make-your-own-sunflower-seed-flour.html
Just checked out your post about how to make your own. This looks totaly different then what I purchased. Mine is darker brown and very very fine, almost like sand. No wonder the recipes I’ve tried out with it also taste (and have the texture) of sand. Will not buy that stuff again and make my own.
Thanks!
Okay, so I think that it must be a defatted and roasted kind that you had (similar to most peanut flour). Mine is almost virtually the same texture as almond flour and i don’t roast beforehand.
Do you think I could use coconut oil and almond milk and make this dairy free?
Yes, I think so. But coconut oil tends to be greasier so I would use a few tbsp less in the cake.
Made this tonight seems that my frosting didn’t set up, still pretty liquid. I put it in the fridge in hopes that it will set over night, any idea why that happened?
I am going to take a stab and say maybe your cocoa powder is the issue? What brand?
Hi! I made just the icing tonight to put on a different cake I had made. My icing tasted wonderful, but it did not set up (harden) like it’s supposed to do. I even put it in the refrigerator and then freezer (for only 15 min.) but it never did. It looked just fine and like I said, tasted great, but I was sad it didn’t look like yours or regular Texas Sheet Cake icing. I did half the recipe as my cake was smaller. And I did not have Swerve, but used another brand of Erythritol/Stevia/Xylitol blend. Any suggestions for next time? Thanks so much!
It’s either the sweetener or your cocoa powder that’s at fault here. I suspect the sweetener because I have found that xylitol is more hygroscopic, meaning it attracts more moisture, than erythritol so glazes and frostings don’t harden.
I would love to try this cake, but my husband is allergic to coconut. Any suggestions for a replacement flour?
Another cup of almond flour would work.
Good Morning,
I have a few questions, as I am new to this whole low carb baking.
1) almond Flour does it need to be fine ground? The almond flour I have is not
2) Swerve I have just the xylitol is that ok to use?
3) Unflavored whey protein, what is it, where do I find it, can substitutions be used, if so what?
4) Powdered, can I grind the granulated, if so how do I measure it.
Thank you!
yes, your almond flour should be finely ground for this recipe. Xylitol is fine for the cake but your icing may not set if you use that. Whey protein powder is available in many places in the health food aisle, also on Amazon. If you can grind your sweetener, measure it after it’s ground.
Hey Carolyn!! I just made this cake and I wanted to let you know that it turned out perfect. I DID poke holes in it cause I wanted the chocolate to run down inside and after it cooled it set up just right for my preference. It’s not hard, but not runny. Just right. The sweetness is perfect and when I cut it with a fork you can hear the moist little swish that it has!! My grandbabies are gonna have a happy time when they get home!! Thank you! They have been ordered to follow a low carb diet by their doctor and this gives them something to look forward too, as their mom leaves the sweets up to me for them, most of the time. She’s gonna like this too. With her work schedule, its hard to find alot of time to bake sweets.
Yay, I am so glad you like it and I hope the grandkids like it too!
Would this work if you leave out the protein powder?
Can something be substituted for it?
Thanks,
Peggy
Protein helps it rise and hold its shape, just like gluten (which is a protein). So if you leave it out, it may be denser. It won’t be such an issue with a recipe like this, though, where it’s spread out in a pan.
Hey there! Would I be able to use the THM baking blend instead of the almond AND coconut flour, or just the almond flour, and then also use coconut flour? Thank you so much!
I didn’t test this recipe with THM blend…I think you could sub it in for both flours but you may find you need a little more oil or liquid because THM baking blend is rather dry.
I just ate the last piece and am sad. I can’t believe how good this was. I will be making it again, I think I’m going to use the peanut butter frosting next. Chocolate and PB are my fav.
I sent food network an e-mail about you, and they actually responded and said you need to contact a production company due to legal reasons. However they did look at your blog which I gave them. I know this because they referred to you as Ms. Carolyn and I did not give them your name. I hope you choose to look into further. On behalf of the 29.1 MM T2 in the US, we need you!!!
Okay, you are the sweetest! Thank you!
If my whey protein powder is vanilla (Jay Robb), would it work to use that and simply reduce the vanilla extract by half? Not sure where to find Swerve, but will check. 🙂 I have Truvia but not sure how it “translates.”
Yes, the vanilla protein powder would be fine. I am not sure what to say about the Truvia, I don’t really use it. I think it’s sweeter than Swerve (Swerve measures like sugar).
Thanks! I’ll start with half and taste the batter. 🙂 I’ve always made an amazing Texas sheet cake (my great-aunt’s family recipe–I can’t take any credit!) so I’m looking forward to being able to make this version that I can eat now.
The whey is there something to replace it with. I am following wheat belly and whey is not compliant. Thanks.
In the cake part, you have two separate water amounts, but I didn’t catch any separation in the directions. Am I missing something?
Yes, I think you are missing something because water is mentioned twice in the instructions. The first 1/2 cup gets boiled with the cocoa powder, the other 1/4 cup gets added to the final batter. Hope that helps!
1/2 C water and 1/4 C water for the cake?
Got to try this.
I want to use Swerve in my regular recipes. The package says it measures cup for cup like sugar. Have you found this to be true?
Yes, it is true. I will say, though, that I tend to use less of it than I would sugar. But my tastes have changed now that I’ve gone sugar-free so I like things LESS sweet.
Yum – so delicious! I need to take a couple of cakes to a retreat this weekend. Do you think it would be ok to make ahead & freeze?
I would freeze without the glaze and add that when you are there, if you can.
Can I use all coconut flour or a combo of coconut & regular APF? I’m out of almond flour & protein powder.
I would not use all coconut flour, it would not be good. Not sure about all purpose…I’d maybe suggest looking at conventional cake recipes.
I just had been reminded about Texas sheet cake by a post somewhere. So glad you made this recipe. My late DH loved it, and I like it myself, so this is very welcome.
I would like to make this but for ease of travel to a reunion could I use a 9×13 pan and if so what modifications?
Thank you
I am sure you could use it and it would need to bake for longer but I don’t know how long. Start with 15 minutes and check every so often after that.
Thank you
Could I use a dairy free alternative instead of the heavy cream and cream? I have Califia Better Half. It is a unsweetened coconut cream and almond milk blend. Would it change the texture or consistency of the frosting and cake?
Were we discussing this on my Facebook page? I think I answered you there, that it’s fine to replace the cream but you still need a dairy-free cream cheese for the frosting.
I just made it, it’s delish! My frosting layer is thinner than yours though, any idea why? I used powdered erythritol and ez-sweetz drops instead of swerve. Love your recipes!!!
Also, how should I store it?
It can be on the counter for a day or two but should be refrigerated if it will be around longer than that.
Oh and it’s thinner because of the drops…you need the powdered sweetener for bulk.
Thanks!
I’ll keep that in mind for the next one, thanks!
