Preheat oven to 375 F.
In a bowl, mash up the bananas. Then add in all the wet ingredients: milk, egg, melted peanut butter, and maple syrup.
In another bowl, you can mix all the dry ingredients: rolled oats, cinnamon, quick oats, salt, and baking powder. Or add them directly into the wet ingredients and mix everything together.
Spray a baking dish with some cooking spray and add in the oats mixture. Top with some sliced bananas if desired.
Bake in the oven for 35-40 minutes, or until fully cooked, when edges and top are lightly browned.
Remove from the oven and allow to cool for a few minutes before serving. Serve with some maple syrup and more sliced banana or drizzle melted peanut butter if desired.
