Sheet Cake

I remember this from when we lived in California. I think Mom might have gotten the recipe from Sister Russick.

Sauce:
1 sq. Margarine
1 c. water
1/2 c. cocoa
Bring to boil and let cool

2 c. flour
2 c. sugar
1 tsp. salt
1 tsp. soda in 1/2 c. buttermilk (or milk soured with a little vinegar)
2 eggs
1 tsp. vanilla

Mix together. Bake in large greased cookie sheet 375 for 20 minutes.

Frosting:
1 sq. margarine
3 Tbsp. cocoa
6 Tbsp. milk
Bring to boil and remove from heat. Add 1 lb. of powder sugar (4 c.) and 1 tsp. vanilla.
