  • Mash the bananas and combine them with the oats and peanut butter in a large mixing bowl. Mix well. Fold in chocolate chips.

Recipe Tips
  1. Make sure to use very ripe bananas. This adds sweetness to the recipe. Ripe bananas are also easier to incorporate into the batter.
  2. I use natural peanut butter which tends to be looser than conventional peanut butter. If you are using conventional peanut butter, consider adding ¼--½ more banana.
  3. These cookies are delicious on their own but also make a great base for so many add-in options. A few of my favorite add-ins are raisins, chia seeds, nuts, and vanilla extract.
  4. If you have a peanut allergy, you can swap it out for any other kind of nut butter
  5. For gluten-free cookies, make sure to look for gluten-free oats.
