Grandma's Brownies

Brownie's 2 day's in a row!  These are my Grandma's brownies. I love them!

1 tsp. vanilla
4 eggs
2 c. flour
2 c. sugar
2 heaping Tblsp. Cocoa
2 cubes melted butter (be careful pouring this in so as not to cook the eggs)
1/2 c. chopped nuts if desired.

Pre-heat oven to 325 degrees.
Mix all ingredients together and place in greased 9x13 cake pan.  Bake for 40-45 Min.  Top with frosting (I usually make my frosting to taste using butter, powdered sugar, cocoa, and milk)
