This is my most popular cake in my home keto bakery. You can make the chocolate cake from scratch, which is very easy or use the Swerve boxed cake mix, before adding the Texas sheet cake glaze.

Best Sugar Free Chocolate Texas Sheet (Keto Friendly)
I believe I have the BEST keto chocolate cake recipe. I’ve worked and reworked my chocolate base until I thought it was good enough to star in my home keto bakery I started in July of 2019. This is one of the most requested cakes along with my Keto German Chocolate Cake.
Swerve Boxed Cake Mix
I also made a sugar free Texas Sheet Cake with the Serve Box Cake mix and it was done in 30 minutes start to stop. It tasted just as good as any Texas Sheet Cake I’ve ever had, and you would never know it’s sugar free.
If you haven’t heard of Swerve, please read my article here.
When Swerve sent me a few box cakes to try, I figured it would be a decent product, as you all know I’m an avid baker and I use powdered erythritol as a sugar substitute to keep it low carb.
The first time I used a Swerve Box Cake, I actually used two boxes to make a double layer cake for a birthday. I made used both a chocolate cake and a vanilla cake to make a double layer cake with this sugar free chocolate frosting for a birthday and people loved it.
Sheet Pan Cakes
I use a quarter sheet pan. I love the USA brand. I’ve had mine for years. It’s warp resistant and it’s the perfect size for Swerve one layer sheet pan cake. They have one slightly larger which also holds the same recipe, and if you use a half sheet pan, just double the recipe.
Texas Sheet cake Glaze is made on top of the stove
The icing is made on top of the stove as soon as the cake comes out of oven, using Swerve, unsweetened cocoa, vanilla, heavy cream, butter and pecans. Do not put butter in pan and melt before adding ingredients. Add butter LAST, so it doesn’t separate.
It’s so good. I’ve seen some recipes that add coconut and you certainly could add unsweetened coconut, which will add even more texture.
If you’re wanting portion control, this is the way to go. I was able to cut 24 pieces of this delicious cake. The pieces freeze very well and you can microwave for about ten seconds when you need that little bite of chocolate.
The Swerve chocolate cake makes this recipe very easy to throw together.
You can make individual Texas Sheet cake as I do in my bakery. This recipe will make 12 individual Texas sheet cakes.
You CAN Make this Keto Texas Sheet Cake from Scratch
I recently made a video which is being edited making this from scratch. The recipe is below in case you don’t want to use the box cake.
Texas Sheet Cake is the perfect cake to make for the holidays, game day or even a tailgating party.

Is the recipe for the chocolate cake from scratch the same for the quarter sheet pan cake and the cupcakes ? Looing forward to making it. Thanks!
YOU are my hero! I LOVED Texas Sheet Cake growing up and since transitioning to low carb/keto have missed many of my favorite treats. I made these cupcakes yesterday in prep for my post-holiday sugar and carb detox, and I treated my husband and I to one of the cupcakes last night. Yes, one for both of us! He had only one question “can I have a whole cupcake tomorrow – they were excellent”
Texas Sheet Cake was always a family favorite, though I never knew its provenance. We called it Hot Fudge Cake. But my mother is now diabetic, and we have gone Keto for her health – and ours! I’ve lost 15 pounds, Hubby has lost 25; Mom has lost 50 pounds and is no longer insulin dependent. We are absolutely Keto believers, and keep it pretty simple and clean. Once in a while you NEED a celebratory treat. Mom turns 80 next month, and I’ve been trying out Keto cake recipes for her birthday. This one, finally, is IT. I left the pecans out because Mom isn’t a fan of nuts or coconut. It’s still perfect. I love how glass-shiny the glaze is. So fancy! Thank you for these outstanding cake and frosting recipes.
Thank you for sharing this information. I’m really on a mission to get people off sugar at least 95% of the time.
I have made this before and it was awesome, I used the from scratch version. I am thinking about making it again for me and my husband for our anniversary. My blood sugar/ketones react badly to swerve…could I sub allulose? If so do you have any recommendations for the amount?
I am super excited to have found this because the Texas sheet cake has always been a favorite, and my husband has recently been diagnosed with diabetes. I’m about to make it for the first time but wondered about the 10 Tablespoons of cocoa powder—that seems like a LOT. If I cut back a bit on it, should I increase the almond flour?
You can take it down to half cup cocoa powder. That’s not really a lot for a chocolate cake. Yes, it’s fine to add two tablespoons of almond flour.
It is the best I really love it thank you
This was delicious. I couldn’t wait for it to cool. That cake recipe is great on its own
Should you at coffee to this recipe to help bring out the flavor of the chocolate?
I have found in recipes from scratch adding coffee helps the flavor.
Curious if you think it would add flavor. If so, how much?
Excellent! A little extra effort to weigh out ingredients makes a substantial difference.
Trying to find diabetic recipes is hard-This is amazing! I love the post about adding cinnamon, but I added sugar free chocolate chips on top. I will try cinnamon next time. Made this with my niece and it’s to die for!!!
I’m so glad you like it.
I saw a recipe to use cake mix to make texas sheet cake cookies, do you think this would work?
Thanks for the recipe. I am going to try this one.
I would use the recipe for the chocolate cake.
I made your cake from scratch and then the icing. It turned out delicious! I added the butter last to my icing ingredients but it still separated and would not combine Bit putting it on the warm cake seemed to soak the butter up. Still great tasting
Next time use cold butter. Continue stirring. It should not separate. But I’m glad you enjoyed it.
Could monkfruit sweenter be substituted for swerve in the recipe?
Yes if you mean a sweetener like Lakanto, you can substitute.
This cake is hands down the best Texas Sheet Cake recipe! Wow! I did add a teaspoon of cinnamon as my regular recipe had it and it was amazing!
I like the idea of cinnamon. I’m going to try that.
Could this sheet cake be made in other flavors? And how would I do that? I have kidney disease and need avoid chocolate because of the phosphorus content.
Yes.I I have a lot of keto cake recipes on the blog. You CAN eliminate the cocoa powder and coffee and add in 1/4 cup almond flour.
Thank you!
This turned out great!! Cake was so moist and the texture was the same as regular non-keto cake! I didn’t have any swerve so I used about 3/4 cup allulose sweetener and 1/2 tsp stevia powder to sweeten the cake and it worked well. I also used chopped cashews instead of pecans in the frosting bc that’s all I had on hand. It was delicious! Definitely will be making this again!
Glad it turned out. I’m sure it was great with cashews.
Can this be made in a 13 x 9″ pan? If so, how long should I bake it, or should I just bake it until it “springs back in the center”?
Yes you can. My guess is 15 to 20 minutes, but check your middle. It should register at 207 degrees F.
Hello — do you think you could double this receipe? If so do you think a half sheet pan?
(I’m going to make this for my father-in laws birthday and take to the senior center for him to share)
I am not sure if you can do that. The reason I say that is that chocolate and almond flour tends to burn. It might be better to make two.
Hi! So I was worried about the cake being too thin in my 9X23(half sheet)…I had a Swerve mix I’ve been wanting to try! I did it in a 9-inch. but I did your icing, kept stirring. It separated when I tried to bring it to a boil, as the recipe states.. so frustrating. I stirred it on low for 5 minutes then turned it up bc it wasn’t ”boiling”… can you tell me what I did wrong? Thanks in advance!
Yes. Did you put your butter in first and melt it? If you did that, the butter separates and will never come back together.
I am wanting the “from scratch” version. Did I overlook it? Thank you.
It’s there in the recipe (in blue).
Oh my cheeses this is hands down the BEST keto dessert I’ve ever made and it was easy!!! Just wondering how to store the cake? Can it stay on the counter or does it need refrigerated?
Thanks for this amazing recipe!!
Yesterday was my birthday and I had the Swerve cake mix on hand so made this amazing cake. I ran out of vanilla so used 1/2 coconut extract in the cake and strong coffee for the water. I used strong coffee in the frosting too instard of vanilla. So delicious!
Oh I like the idea of the coffee in the icing. Thanks.
Guys, Thanks For sharing this Great Recipe. My Family Loved it. I am definitely sharing this recipe and this website with my friend. Hope they also love it. Thank you again for sharing such a great recipe.
Just finished making this and I have to admit I was sceptical being a big fan of the original Texas sheet cake but it turned out amazing!!! Followed the directions exactly as written and loved the end result! Thank you so much for this awesome recipe! It’s by far the best low carb dessert I’ve made so far!
Janie
Thank you so much for letting me know.
Have mercy! I had no idea Swerve made cake mix! I am so ordering some and making this! Thank you!
The best!
So moist and tastes just like the original recipe!
This cake looks amazing. Do you think I could use Grape Seed oil instead of avocado oil. It’s what I have on hand.
You can. That’s not an oil I choose, but it will work.
THIS CAKE WAS AMAZING!!! I made the one from scratch and made my own topping of just whipping cream, cream cheese, vanilla, and sweetner. I garnished it with fresh strawberries… DELICIOUS!! my mon-keto hubby Loved it as well!!
Finally a krto cake I enjoy!!
Thank you. The one from scratch is my favorite too.
This is cake is so yummy either way you make it, it’s a favorite in our house! Do you know how to stop/reduce the crystallization of the erythritol/swerve in the frosting. I’m trying to get a smoother texture for the frosting, I’m not sure if it’s my technique or if that’s just how it’s supposed to be. It kind of has a light sugary crunch like undissolved granulated sugar even though I’m using confectioners swerve.
Unfortunately you can’t stop that crystalization. It’s the chemical reaction of the swerve. One thing to try…instead of that icing…try the chocolate ganache recipe here and add pecans.
Oops, just left this comment for the wrong recipe!
This cake is really good.- soft, moist, chocolaty. I made the from scratch version. It will be my sole go to chocolate cake recipe from now on. Also could be good as a brownie with the addition of chocolate chips. The frosting hardens just enough that it is like a layer of fudge.
Pre-keto I had a recipe for peanut butter sheet cake with pour over peanut frosting. What do you think of substituting all of the cocoa powder with peanut powder?
Kathy, not sure but would be so interesting to try.
Excellent and easy to make. Froze cut up squares and they were just as delicious. My husband loved and you can’t tell it’s sugar free.
Would love a recipe to make sugar free cake with maple frosting that can be pores over the cake like this one
Hmm not to hard I think. I’ll work on that.
This turned out great, and even my sugar-loving husband liked it! I used the swerve box mix that I bought to try out, but I’ll definitely try again using the homemade cake version. Thank for a great recipe!
I really do like my homemade chocolate cake. Hope you try it.
This was absolutely delicious! I couldn’t believe how close it was to the texas sheet cake I used to eat before going low carb. It was also fun to watch the frosting dry so fast. 🙂 I made the cake from scratch and so happy with the result! Thank you.
Thank you. So glad you liked it.
I would like to add ground espresso to this. How much would I add and do I have to add a little more liquid if I do?
I can’t speak to this because I’ve never baked with ground espresso.
Why do you only cook the Swerve Cake mix cake for only 15 minutes when it regularly cooks for 25-30. I see you pour the chocolate frosting on it, does that help cook the middle of cake more?
Because it’s spread out on a sheet cake.
This Texas sheet cake looks so delectable and sugar free?! Wow. Nice work! Pinning now:)
Under the instructions to make the cake from scratch, #5 says Add coffee and milk. Is this a typo? I don’t see it in the ingredients list and I haven’t seen coffee used in making TX sheet cake before. Thank you.
I do like coffee in my chocolate cake, but I’ve taken it out.
My family LOVED this chocolate cake. I substituted coconut cream for the whipping cream and it turned out just fine(my husband has dairy allergies). The cake was moist and delicious. Hard to believe it was Keto. I will definitely make it again. I was wondering if you had a break down of the calories, protein, etc.?
I figured the macros and put them in the recipe. 2 net carbs. This is for the cake made from scratch.
Thank you for letting me know. I may do that for those who want dairy free.
Macros please?
There are 24 servings and 2 net carbs. I added it in. This is for the cake made from scratch.
What are the macros if you use the Swerve cake mix ?
Using the Swerve cake mix, the macro’s are 3 net carbs.
Could you post the nutritional information for this recipe? I am diabetic and trying to avoid carbs as much as possible. Thank you so much for your amazing recipes!
Thank you for this recipe & yummy-looking photo. Oh, what s fantastic looking cake! Soon as I decide whether to purchase the mix or take a stab at your recipe version, I’ll bake it up. Your frosting recipe alone has gotten me exited! 👏🏼 😋
I am just making this frosting recipe but I’m confused it asks for half a cup of unsalted butter and then later down in the recipe it says to mix the vanilla and salt and there’s no salt in the recipe. Can this be made with half a cup of salted butter ? I use Kerrygold
I just added the salt. If you use salted butter, skip salt.
