Brownies for a Crowd

from Sister's Cafe

3 cups sugar
1/2 cup + 1 Tbsp cocoa
1/2 tsp salt
1 1/2 cups melted butter
5 eggs
2 1/2 tsp vanilla
3 cups flour

Mix together and spread on a buttered cookie sheet (standard stainless steel). Bake in a preheated 350 oven for 30 minutes. Be sure to not overcook. Frost

(cookie sheet size)
Frosting:
1/2 cup butter
3 1/2 tsp cocoa
6 TBsp milk
1 tsp vanilla
Powdered Sugar--I have never measured. I just add until I get the consistency I want. If it becomes to thick I just add a bit more milk.
Boil together, remove from heat and add powdered sugar. You can add nuts into the frosting or sprinkle on top if you would like.
