Step 1

Preheat the oven to 375 degrees. Mash the bananas with a fork until they are about half liquidy and half chunky. Start with just three bananas and add another if needed to make 1.5 cups.

Step 2

Add the mashed bananas to a large bowl. Warm the peanut butter slightly in the microwave so that it is more fluid and can mix in easier. Add the peanut butter, eggs, brown sugar, vanilla, baking powder, and salt to the bowl. Whisk these ingredients together until smooth. Add the milk and whisk again.

Step 3

Add the dry oats, chocolate chips, and shredded coconut to the bowl. Stir everything together until evenly combined. Lightly coat the inside of an 8×8 inch casserole dish with non-stick spray. Pour the oat mixture into the casserole dish and bake for 45 minutes in the preheated oven.
