Banana Chocolate Chip Cookies

Bananas quickly over-ripen in the summer and this makes them perfect for baking. My go-to solution is to make banana bread, but this cookie recipe is a nice alternative.

1 1/2 to 2 ripe bananas
1 egg
1 1/4 cup flour
1/2 teaspoon salt
1 teaspoon baking powder 
1/3 cup butter softened
1/3 cup brown sugar
1/3 cup granulated sugar
1 teaspoon vanilla
1 cup chocolate chips
1/2 cup chopped walnuts

Lightly grease cookie sheets. Sift flour, baking powder and salt. Cream butter, sugars, and vanilla. Add egg and beat until fluffy. Mash banana and add to butter mixture. Gradually mix in dry ingredients until well blended. Fold in chocolate chips and nuts. Drop by teaspoon onto lightly greased cookie sheet, two inches apart. Bake at 375 degrees until edges are golden brown, about 10 to 12 minutes.
