Banana Bread

1 c. sugar
1/4 c. butter, softened
1 2/3 c. mashed  bananas (about 3-4)
1/4 c. milk
1/4 c. sour cream
2 large egg whites (I just throw the whole egg in)
2 c. flour
1 t. baking soda
1/2 t. salt
chopped walnuts (opt)

Preheat the oven to 350 degrees. Beat the sugar and butter together until well blended. Add the banana, milk, sour cream and eggs. Beat or mix well. Add in flour, soda, and salt. Beat until well blended. (Walnuts are good to add here if desired.) Coat bread pans with cooking spray. Bake for 45 minutes or until wooden pick inserted in center comes out clean. Cook for 10 minutes in pans on a wire rack. Remove from pans. Cool completely on a wire rack.
