Ingredients for Frosting
1stick8 tablespoons butter
6tablespoonscreammilk, or buttermilk
1/2 - 1cuppecanschopped (optional - I don't use them)
3 3/4cups3.75 cups confectioners (powdered) sugar
Instructions for Making the Cake
In a sauce pan, bring oil, butter and cocoa powder to a boil.
Move to a mixing bowl after items in step one have come to a boil.
Mix the sugar, flour, and salt. Pour them into the mixture that you just put in the bowl. Beat well.
Add in Coca Cola. Blend well.
Add eggs, buttermilk, baking soda, and vanilla. Beat well.
Pour into a greased and floured sheet cake pan. (I used a 15-inch cookie sheet that had one inch sides. A jelly roll pan is also a great option.)
Bake at 350 degrees for 20 - 25 minutes. Plan to frosting the cake shortly after taking the cake out of the oven.
Instructions for Making the Frosting
Very shortly before the cake is done or immediately after taking it out of the oven, start making the cake's froting.
In a saucepan, combine the butter, cocoa powder, and milk. Heat until butter melts.
Beat in the remaining ingredients, and pour/spread on the hot cake.
Cool cake before cutting.
The yield on this recipe all depends on how big of pieces you are cutting. I would imagine you could make large pieces and cut 30 pieces. I often cut it so that I get around 40 pieces of cake from the pan.
