Heirloom Chocolate Sheet Cake (adapted to be Gluten Free)

from Heirloom Meals

Cake Ingredients
My friend Erin Gernon shared her family recipe for a chocolate birthday sheet cake.  She told me that this cake was a staple at every birthday party.  So, I thought I would take the basic premise of the cake and turn it into a gluten free delight.  My husband, Jim, who has celiac's disease was in heaven.  His smile was a mile wide with pleasure.  But, best of all, anyone who ate it had no idea it was gluten free!

  • 2 cups gluten free flour (I love King Arthur Flour)?
  • 1 teaspoon xanthum gum?
  • 2 cups sugar?
  • 2 sticks unsalted butter?
  • 1 cup water?
  • 1/4 cup unsweetened cocoa?
  • 2 eggs?
  • 1 teaspoon soda?
  • 1/2 cup buttermilk?
  • 1 teaspoon vanilla


  1. Preheat the oven to 350 degrees.
  2. Combine flour, xanthum gum and sugar in a large bowl.
  3. Bring the butter, cocoa, and water to boil in a pan. Pour over the flour mixture and beat.
  4. In a separate bowl, mix the eggs, baking soda, buttermilk, and vanilla and pour over the flour mixtures and beat well.
  5. Spread onto a jelly roll pan lined with parchment. Bake in the middle of the oven for thirty minutes.

?Frosting Ingredients:

  • 1 stick butter?
  • 1/4 cup cocoa?
  • 1/3 cup buttermilk?
  • 1 lb powdered sugar?
  • 1 teaspoon vanilla?
  • 1 cup chopped pecans (optional)?
  • 1/4 teaspoon salt

Bring butter, cocoa, and buttermilk to a gentle boil. Add the other ingredients and combine until smooth. Frost the cake while it is are still warm.
