How to Make Chocolate Cake
STEP 1: In a large mixing bowl, add 2 cups sugar, 2 cups self-rising flour, and 4 Tbsp. cocoa. Mix together and set aside.
STEP 2: In a saucepan, add 1 stick of butter, 1 cup oil, and 1 cup water. Bring to a boil for 1 minute, then pour over the dry ingredients in the mixing bowl. Beat dry and wet ingredients together for 1 minute on medium speed with a mixer.
STEP 3: In a separate bowl, whisk 2 eggs and ½ cup buttermilk. Pour into the mixing bowl with the rest of the ingredients and beat for 1 minute on medium speed until everything is combined.
STEP 4: Pour batter into a greased and floured 13 X 9 inch sheet pan or dish. Bake at 350 for 35 minutes.
How to Make Chocolate Icing
STEP 1: In a separate saucepan, mix 1 stick butter, 3 Tbsp. cocoa and 4 Tbsp. milk together. Boil for 1 minute. Mix well and remove from heat.
STEP 2: Add 1 lb. powdered sugar and 1 teaspoon of vanilla and blend with a mixer until smooth. If icing is too thick, add tiny teaspoons of milk until it is shiny. Taste the icing and if it's too grainy, blend it with a mixer until it becomes smooth and creamy.
STEP 3: Pour icing over cake starting at the edges and working towards the middle until it covers the top of cake. Allow icing to cool before serving.

This is what we call Texas Sheet Cake. I first tasted this cake 57 years ago at a meeting I attended. It was the absolute best chocolate cake ever! The recipe I managed to get did have a little cinnamon in it. I thought the buttermilk is what made this so Divine. Yummy 😋 I absolutely love this cake!
Hi Anna! It seems that this cake is called different names depending on the region. Some folks tell me that they put nuts on top. Others say they put Coca Cola in it! All I know is that it's the most delicious cake I've ever made in my life! Thanks for sharing! 🙂
is it buttermik for the icing or regular whole milk ?
Hi Lynn. It's regular milk.
Some recipes call for baking soda to offset the acid in the coco powder and/or buttermilk. I don't understand why this one doesn't?
Also could you substitute Kefir for Buttermilk?
Hi Charlene. This is an old fashioned recipe handed down through the years. It calls for self rising flour which already comes with the proper measurement of baking powder and salt. It works perfectly without the baking soda. I have never tested it with Kefir so I can't guarantee the results.
This is one of my families’ favorite cakes! I think I have made this cake over 20 times since you posted this recipe! I remember having this cake at my grandmothers but never had the recipe. Thank you for sharing my friend!
