3/4 c. butter
2/3 c. sugar
2/3 c. brown sugar
1 1/2 tsp. vanilla
3 ripe bananas, mashed
1 egg
2 1/4 c. flour
2 tsp. baking powder
6 oz. chocolate chips
1 can vanilla icing

Preheat oven to 350 degrees. Cream butter and sugars; add vanilla. Sift flour and baking powder. Add to creamed mixture. Add chocolate chips. Bake for 35 minutes in a greased 9x13 inch pan. When cool, frost cake and cut into small squares. Flavor improves as it ages!
