Texas Sheet Cake

 I got this recipe from Cliss. 

In a small saucepan melt:
2 cubes margarine or butter
3 Tbsp. cocoa
1 cup water
1 tsp. vanilla

In a mixing bowl, mix:
1/2 cup buttermilk (or 1/2 milk and 1 tsp. vinegar)
1 Tbsp. vinegar
2 eggs
1 tsp. baking soda

Add saucepan mix, then add:
2 cups flour
2 cups sugar
1 tsp. salt

Pour into greased cookie sheet and bake at 350 degrees for 18 - 25 minutes.

Frosting

1 cube butter or margarine
3 Tbsp. cocoa
5 Tbsp. milk
1 tsp. vanilla
1 lb. powdered sugar (about 4 cups)

Mix and frost while cake is warm, but not hot, so the frosting cools down as a smooth glaze.
