3 eggs
1 1/4 c. sugar
4 ripe bananas, mashed
2 tbsp. sour cream

Preheat oven to 350 degrees. In bowl, sift together flour, baking powder, and baking soda and set aside. In separate bowl cream butter, eggs, and sugar together. Add mashed bananas. Stir the dry ingredients into this butter mixture, then add sour cream and mix well. Blend in nuts, chips, and vanilla.
