Low carb cake, a copycat chocolate Texas sheet cake topped with pecan chocolate frosting. Y’all need to try this favorite cake Keto-style!

Low Carb Cake A Copycat Texas Sheet Cake

Ok, before I get y’all mad at me for tweaking an American classic cake like Texas sheet cake or for using the word, y’all, hang on to your chonies…

Y’all doesn’t roll off my tongue like it did for my late father-in-law, a true Texan. Actually, he used words like fixin’ more often. Regardless, as soon as he spoke you could hear that drawl in his voice that only Southerners have.

Talking with a Southern drawl isn’t a way of life for me and neither is baking a flourless cake, but why not give it a go?!

Low Carb Chocolate Cake

So do me a favor and just let this native Californian turn a crazy delicious cake into a much healthier chocolate delight!

Can you get the same rich tasting flavor of Texas sheet cake in a grain-free cake? Yes, yes you can!

It’s hard though, especially when playing with carbs because you basically must eliminate the flour base. What? No flour in this cake, nope, none.

Remember the healthy banana muffin recipe I shared? I mentioned that you would have extra flour in the baking mix, which is what I used for this recipe with heaping spoonfuls of cocoa!

Gluten-free baking mix

To refresh your memory I used a mix of oat fiber, flaxseed meal, protein powder, and coconut flour in that muffin recipe. For this recipe I added unsweetened cocoa powder!

Except for the flour base and a change in the sweetener, I keep true to the original Texas sheet cake that I’ve been making for years. Lots of butter, buttermilk, and the hot water keeps this cake super tender!

Buttermilk substitute

You only need a 1/2 cup of buttermilk for this recipe, so if you don’t have it on hand there is a simple hack that I use often.

In a small measuring cup add one tablespoon of white vinegar or lemon juice, then add enough milk to reach the 1 cup mark. Stir and let the mixture sit for about five minutes. Once it thickens a bit it’s ready to be used!

I need a dairy free version. Have you used white vinegar in coconut, almond, macadamia, etc. milks before?

  I haven’t tried a dairy free version. You may leave it out. Let me know how it goes!

Could I use almond flour instead of the baking mix?
- Sandra Shaffer

  Hi Carla, You would definitely need to experiment a bit. I would also include some whey protein to help with the structure.

    Sandra, Like Carla, I am also interested and n using almond flour to Make the Texas Chocolate Sheet Cake instead of the baking mix. I am not expert enough to know how much almond flour to use or whey protein. Would you mind elaborating a little more about how much of each I should try? Thank You So Much!
    Sincerely,

      Hi Loretta! I haven’t tried making this with just almond flour. If I was going to experiment with different flours I would probably incorporate a bit of coconut flour. Protein powder will also help with the texture. I hope this helps! I just can’t provide exact measurements without redoing the recipe.

        I made it using the same amount of almond flour as the recipe called for baking mix. Instead of the granular swerve, I used the same amount of Great Value Granulated No Calorie Stevia made with Stevia Extract. On the package it stares Great for Baking! Also instead of using 2 sticks of butter, I used 1 stick of butter & 1/2 stick of butter flavored shortening. Those are the only changes I made & the texture was just like a non keto Chocolate Sheet Cake but the after taste was rather strange. Do you think that came from the Great Value Stevia? Would you recommend using monk fruit sweetener instead?

        Stevia only can be harsh. That may be what you are tasting.
