5 from 6 reviews


Slightly sweet, healthy peanut butter banana cookies taste like banana bread and are made with just 3 ingredients! Perfect for breakfast, snack, or even a light dessert.


  • ½ cup mashed, ripened banana (about 1 medium banana)
  • 2 tablespoons peanut butter
  • 1 cup rolled oats
  • ¼ cup pecans or walnuts, finely chopped – optional, but recommended


  1. Preheat oven to 350°F. Line a baking sheet with parchment paper or greased foil. Set aside for later.
  2. Peel bananas and add to a medium bowl. Using a pastry cutter or fork, mash bananas until nearly smooth.
  3. Add in peanut butter. Whisk until thoroughly mixed. Fold in oats to create the dough. Fold in pecans or nut of choice.
  4. Using a medium cookie scoop, scoop and drop balls of cookie dough onto the prepared baking sheet. Using a fork, flatten cookies to desired thickness.
  5. Bake for 10-14 minutes. Mine took 12 minutes. Place pan on a cooling rack to allow cookies to set, for about 5 minutes. Then, using a heatproof spatula, lift cookies directly onto the cooling rack. Cool for about 10 minutes. Enjoy!


Storing Instructions: Cool cookies completely, then store in an airtight container in the refrigerator for 3-5 days.

Freezing Instructions: Store cookies in an airtight, freezer-friendly container in the freezer for 1-2 months. Allow cookies to thaw for about 10 minutes at room temperature before enjoying. Or heat in the microwave in 10-second increments until just warmed, being careful not to burn.

How to make Vegan: keep the recipe as-is. 😉

How to make Gluten Free: use gluten free rolled oats.
