  • Preheat the oven to 350 degrees F and line a large baking sheet with parchment paper and set aside.
  • In a large bowl, mash the bananas with a fork until only small lumps remain. Add the peanut butter, oatmeal, and chocolate chips to the mashed banana and mix until evenly combined.
  • Use a medium cookie scoop to measure heaping scoops of the cookie dough onto the prepared baking sheet. Use your fingers or palm to gently flatten the cookies.
  • Bake for 15 to 17 minutes, remove from oven and allow to cool on the baking sheet for a few minutes before transferring to a cooling rack to cool completely.



  • To Freeze: Make according to recipe directions and allow the cookies to cool completely before adding to an airtight container and freezing for up to 3 months. Thaw at room temperature. 
  • You could also add in dried cranberries, chopped walnuts, and more for added texture and flavor.
  • Nutritional information is an estimate per cookie including chocolate chips.
