What Makes Texas Sheet Cake so Unique

Texas sheet cake is one of the most classic sheet cakes. It is filled with wonderful chocolate flavor. This recipe especially highlights the chocolate flavor by boiling the butter, cocoa, and water together which activates the flavor.

It also features a wonderfully smooth chocolate pecan buttercream frosting to top off an already moist sheet cake.

Why is it called Texas Sheet Cake and what makes it different?

It is uncertain how Texas Sheet Cake got its name, but maybe it’s because it’s a big cake and, as you know, everything is bigger in Texas.

Texas sheet cake is also very similar to German chocolate cake. However, the main difference between the two is that German chocolate cake requires a more complex, multistep process, whereas Texas sheet cake is made easier by combining everything in one bowl.

Replace the Buttermilk

If you don’t have a jug of buttermilk at home, you can make your own. Combine 1 cup whole milk (or whatever milk is in the fridge) with 1 tablespoon of distilled white vinegar or lemon juice. Stir and let it sit for 5 minutes. You’re ready to go!

What size pan is needed to make this Texas sheet cake?

For this recipe, you will use a jelly roll pan that is 18″x26″. Some people like to use two half-sheet pans. If you would like to make this as a layer cake, then I would suggest using two 8-inch cake pans, you could also make this in a 9″x13″ baking pan.

    You left out the tsp. cinnamon in the cake mix. That’s the main reason I love this cake because the cinnamon takes away the heavy chocolate flavor.
    This is the very best cake and I have served it over and over through the years
