Texas Turtle Sheet Cake

Heat the oven to 350 degrees. Prepare a 9×13-inch baking pan by greasing and flouring it. In a big bowl, mix self-rising flour and sugar. Put aside.

In a pot, mix 1 cup of butter, 1 cup of coffee, and 1/3 cup of cocoa. Heat until boiling, stirring all the time. Pour the mixture into the dry ingredients that have been prepared. Use a hand mixer to blend the wet and dry ingredients together on medium speed until they are well mixed. Put eggs and half a cup of buttermilk. Mix at a medium speed for about one more minute, until everything is well mixed.

3. Put the mixture into the baking pan and bake for 25-30 minutes. When the cake is finished baking, you can check if it’s ready by inserting a toothpick or fork into the middle of the cake. If it comes out clean, the cake is done.

Make the frosting. In a small pot, mix 1/4 cup of butter, 4 tablespoons of buttermilk, and 3 tablespoons of unsweetened cocoa powder. Heat until boiling, stirring often.
