Preheat oven to 350 degrees. Gather your ingredients so that you have everything close at hand on the counter or table. Prepare your ingredients. Mash bananas in a small bowl. Using a nut chopper, chop the pecans or English walnuts. Set both aside until ready to use.
In a large mixing bowl bowl, cream together the softened butter and granulated sugar. Add egg, vanilla extract, and Princess Flavoring. Mix until well blended.
Stir in bananas and sourdough.
In a small bowl, combine the all-purpose flour, salt, baking powder, and baking soda. Stir into batter until just blended. Fold in chopped nuts.
Spoon into small loaf pans that have been greased with cooking spray. Bake in preheated oven for 40-45 minutes until bread is set in center.
Cool on wire racks. Makes four small loaves or two regular-sized loaves. Freezes well.
