Preheat oven to 350℉. Gather your ingredients so that you have everything close at hand on the counter or table.
Prepare the Ingredients
Mash 1 1/2 cups mashed bananas in a small bowl.
Using a nut chopper, chop 1 cup pecans or English walnuts. Set both aside until ready to use.
Make the Quick Bread
In a large mixing bowl bowl, cream together 1/2 cup butter (softened) and 1 cup granulated sugar. Add 1 large egg, 1 teaspoon vanilla extract, and 1 teaspoon Princess Flavoring. Mix until well blended.
Stir in mashed bananas and 1 cup sourdough starter.
In a small bowl, combine 2 cups all-purpose flour, 1 teaspoon salt, 1 teaspoon baking powder, and 1/2 teaspoon baking soda. Stir into batter until just blended. Fold in chopped nuts.
Prepare the Bake the Bread
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 mini loaves or two regular loaves. Freezes well.
