Banana Whackies ;0)

2/3 cup butter
1 1/2 cup sugar
2 eggs (divide yolk and whites)
1 cup RIPE bananas (2-3 bananas)
1 1/2 cup flour
1 tsp. baking soda
1/4 tsp salt
4 TBSP sour cream
1/2 tsp vanilla
*You can add 1/2 bag chocolate chips, raisins, or nuts*
Preheat oven at 350 degrees. Grease a 9x13 baking pan. Cream butter, sugar, bananas and yolks. Sift in dry ingredients (I add the chips in at this point) . Mix the sour cream and vanilla. Beat egg whites and then gently fold into mixtures. Pour mixture into the pan. Bake for about 35 minutes! Enjoy...
