The banana started to brown, usually by then my kids do not like to eat it so instead of getting rid of it we either make banana bread, banana muffins or I freeze put it in the ziplock bag for a smoothie later. My son Deven asked for banana muffins for breakfast. 
Ingredients:
1½ cups all-purpose flour
1 teaspoon baking powder
1 teaspoon baking soda
½ teaspoon salt
3 large bananas, mashed
¾ cup white sugar
1 egg
1 teaspoon vanilla
⅓ cup butter, melted
Directions:
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.
Combine bananas, sugar, egg, vanilla and melted butter in a large bowl. 
Fold in flour mixture, and mix until dry ingredients are just combined. Do not over mix. Scoop about ¼ cup of batter each muffin tin.
Bake in preheated oven for 15-20 minutes. Muffins will spring back when lightly tapped.
