4 T. cocoa

In a saucepan, melt the marg(or butter) and mix in water, oil and cocoa. Bring to a boil, dissolving cocoa well. Remove from heat. Add sugar, flour and eggs and beat well. Dissolve soda in buttermilk, and mix in with vanilla. Bake in a 10x17 inch greased cookie sheet (the kind w/ sides) at 325 (degrees Fahrenheit or 163 degrees Celsius) for 20 minutes.
***if you don’t have buttermilk, you can add ½ teaspoon of lemon juice to regular milk and let it stand for about 10 minutes to substitute.

Frosting:
1 lb powdered sugar
¼ C. cocoa
¼ C. milk
½ C. butter

put all ingredients in saucepan. Stir well over medium heat until everything dissolves. Remove from heat and add 1 t. vanilla and frost while warm

FOR MUD PIE: (this is how I like it)
Remove cake from oven and cover with mini-marshmallows and return to oven for 5 minutes. Remove from oven and wait just a couple minutes, then pour the frosting over all the top.
ENJOY-
