I made these into muffins, but the recipe calls for a loaf pan. If you make muffins, you will have to adjust the time you bake them.
To prepare bread, combine first 5 ingredients in a large bowl. Beat with mixer at medium speed. Add sugars and beat until blended. Spoon flour into dry measuring cups, level with knife.
Combine flour and next 5 ingredients in a small bowl. Add flour mixture to banana mixture, beat just till blended.Stir in nuts.
Pour batter in a 9x5 inch loaf pan coated with cooking spray. Bake at 350 degrees F for 1 hour and 5 minutes or until a wooden pick inserted in center comes out clean.
Remove from oven. Cool 10 minutes in the pan on wire rack. Remove bread from pan, cool.
To prepare glaze, combine powdered sugar, milk, and 1 Tbsp. peanut butter in a small bowl, stirring with a whisk. Drizzle over bread.
