- STEP 1
Preheat oven to 350 degrees F (175 degrees C). Coat muffin pans with non-stick spray, or use paper liners. Sift together the flour, baking powder, baking soda, and salt; set aside.
- STEP 2
Combine bananas, sugar, egg, and melted butter in a large bowl. Fold in flour mixture, and mix until smooth. Scoop into muffin pans. You may add chopped walnuts to the top of the muffins for some extra crunch.
- STEP 3
Bake in preheated oven. Bake mini muffins for 10 to 15 minutes, and large muffins for 25 to 30 minutes. Muffins will spring back when lightly tapped.
