Instead of buying a box mix, here is Gwen's version of a simply brownie.
1 stick margarine, melted
1 cup sugar
2 Tablespoons cocoa
2/3 cup self rising flour
1 teaspoon vanilla flavoring
Optional: 1/2 cup chocolate chips or pecans or both!
Stir in all ingredients and pour in a greased 8x8 dish. Bake at 350 until done or toothpick is clean when tested.
