Preheat oven to 350 F.
First, you'll want to mash the bananas in a medium-sized bowl. Make sure that they are well mashed.
Then add in the oats and mix the oats and bananas together. This will serve as the base for your Chunky Monkey cookies.
Then, add in the peanut butter. The mixture will be really thick, so make sure to mix everything really well.
Lastly, add in the baking powder, maple syrup, and chocolate chips. Mix everything together.
Then, scoop the cookies into 1 inch balls and place on a baking tray. Slightly flatten the cookies out with a spoon or fork, as they will not flatten themselves while baking.
Bake at 350 for 10-15 minutes.
