My husband always requests this cake for his birthday. It is very similar to Texas Sheet Cake, but the cake is thicker. Hope you enjoy it too.
2 Cups Sugar 2 Cups all-purpose Flour 1 Cup Coca-Cola 1 ½ Cup small Marshmallows 1 Cup Butter or margarine 6 Tablespoons cocoa 1 teaspoon baking soda 1 Cup buttermilk 2 Eggs, beaten 1 Teaspoon vanilla extract
½ Cup Butter 4 Tablespoons Cocoa 6 Tablespoons Coca-Cola 1 box (1-pound/16 oz.) Powdered Sugar 1 teaspoon Vanilla Extract 1 Cup chopped Pecans, optional
Preheat oven to 350 degrees. Grease and flour a 13×9 pan, set aside. In your mixing bowl stir together flour and sugar. In a medium saucepan melt the butter; and then add marshmallows, cocoa, and Coca-Cola. Heat until marshmallows are melted. Pour this mixture over the flour and sugar, mix to combine. Add beaten egg, soda, and buttermilk. Add vanilla and mix to combine.
Pour batter into the prepared pan. Bake for 40-50 minutes, or until a toothpick poked into the middle of the cake comes out clean.
Prepare the frosting while the cake bakes. In the same saucepan you used for the cake, melt the butter, add coke, and cocoa. Bring to a boil. Pour this mixture over the powdered sugar and beat until creamy. Add pecans, if using, and vanilla. Spread over the warm cake.
To make Gluten Free, use Gluten Free Flour mixture instead of all-purpose flour and add ½ teaspoon xanthium gum. Increase baking soda to 1 ½ teaspoons.
