Bethann's version of Texas Sheet Cake

I pour the icing on after pulling it out of the oven. Here's my version. My Kindergarten teacher gave my mom this recipe. I'm forty-four, so this one has been a hit in my life for 39 years--and counting!

Texas Sheet Cake

1)Bring to rolling boil:
2 sticks oleo (I use butter)
1 C water
Stir and add:
4 tablespoons cocoa
2 C sugar

2)Sift together in a large bowl:
2 C flour
1/2 teaspoon salt
1 teaspoon baking soda

3)Add cooked mixture

4)Add:
2 eggs
1/2 C sour cream

Beat well! Pour into greased 17X11 jelly roll pan. (I use my Pampered Chef pan.) Bake at 400 degrees for 12-15 minutes

Chocolate Frosting

Bring to light boiling stage:
1 stick oleo (again, I use butter)
4 tablespoons cocoa
6 tablespoons milk

Remove from heat and add:
1 C nuts
1/2 teaspoon vanilla
Almost 1 box (about half a 2lb bag) of powdered sugar

Beat and pour onto hot cake.
