Preheat oven to 350 degrees. Place parchment paper on a cooking sheet and set aside.
Place pancake mix in a large bowl.
In a separate bowl, combine peanut butter, bananas, and maple syrup. Add to pancake mix and mix until combined. If batter is too dry, add milk and mix until desired cookie dough consistency. Fold in chocolate chips.
Drop cookie dough using a spoon onto cooking sheet. Use fingers to shape into cookie shapes. Repeat with remaining batter, or about 16 cookies. Add banana slice on top of each cookie, if desired.
Bake for 12 minutes, or until done.
Enjoy!
