Grandma Hintz's Texas Sheet Cake

Cake

2 cups flour
2 cups sugar
1/2 tsp salt
2 cubes butter
1 cup water
4 tbsp cocoa
1/2 cup sour cream
2 eggs
1 tsp baking soda

In a large bowl/mixer, put sugar, flour and salt. In a heavy pot bring butter, water and cocoa to a boil.  (I use a 4 cup measuring cup in the microwave)
Take the cocoa mixture from the heat as soon as it boils and immediately add to the dry ingredients.  Next add in the sour cream, eggs and baking soda.  Mix well after adding each ingredient. The batter will be thin. Bake in a foil lined, greased large cookie pan with high sides @ 375 degrees for 20-25 minutes. Frost immediately.

Frosting

1 cup chopped nuts
2 cubes butter
1 tsp vanilla
(1/3 cup) 6 tbs evaporated milk
4 tbs cocoa
3 cups powdered sugar

Boil milk, butter & cocoa in heavy pot (again, I use the microwave) until bubbling.  Add the remaining ingredients. Spread over the cake immediately.
