Gluten-free Texas Chocolate Sheet Cake

One of my favorite desserts at my family’s parties was my Aunt’s famous Texas Chocolate Sheet Cake (aka Chocolate Cafeteria Cake). Lucky, for me (and you) she shared it with me and I modified it to be gluten free. This cake is so moist and tasty; a real crowd pleaser! My husband and boys are requesting me to make this cake all the time now.

  9. 1/4 cup unsweetened cocoa
  10. 1/2 cup buttermilk (See notes)
  11. 1 teaspoon vanilla extract
  12. 2 large eggs
  1. 6 tablespoons butter
  2. 1/3 cup milk
  3. 1/4 cup unsweetened cocoa
  4. 3 cups powdered sugar

  1. Preheat oven to 375°.
  2. Grease and dust 13x18-inch jelly-roll pan or 13x9 pan
  3. In a large bowl combine dry ingredients: flour, sugar, baking soda, xanthan gum, ground cinnamon and salt
  4. In a small saucepan bring water, butter, and cocoa to a boil (for about 30 secs), stirring frequently.
  5. Remove from heat and pour into flour mixture.
  6. Mix until well-blended.
  7. Add buttermilk, vanilla, and eggs; mix batter well.
  8. Pour batter into prepared pan.
  9. For jelly roll pan bake at 375° for 17-20 minutes or until a toothpick comes out clean.

Texas Sheet Cake is suppose to be baked in a a big 13 x 18″ sheet pan or jelly roll pan so it is Big (like Texas) and it is a thin cake. I do not own one and I like my cake slices thick so I make mine in a 13×9 pan and it comes out wonderful and delicious every time. Either way Thin and Big or Thick you can’t lose with this moist, chocolaty and rich cake!

Hope you enjoy this recipe! Check out my other gluten-free recipes HERE.


  1. Who doesn’t love chocolate cake? I’m going to have to give this version a try!

  2. So- we made this yesterday for my daughter’s 12th birthday. One of her friends is gluten free so we decided to make it together for the girls. It was a fun baking project for the 12 year olds and it was delicious! Couldn’t tell it was gluten free, it was just yummy. We only used 1.5 cups of sugar for the cake instead of 2 and also less powdered sugar for the icing. Delicious, and thank you for sharing.
