Preheat your oven to 375°F.
In a large bowl, mix together the oats, protein powder, and baking powder.
In a separate bowl, add 3 of the ripe bananas and mash. It may help to microwave them for a bit to soften. Cut the other banana into slices to go on top of the oatmeal.
Whisk together the mashed banana, egg whites, honey, milk, and 1 tbsp of melted butter. Pour in the dry ingredients and 1 tbsp of the chocolate chips. Mix to combine.
Spray a 13"x9" pan with oil and add the oat mixture. Top with the sliced banana and chocolate chips.
Bake for 35-40 minutes.
This recipe makes 6 servings. Cut the oatmeal into 6 equal pieces.
