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!
