Ingredients

Scale
  • 2 cups rolled oats

  • ½ cup peanut butter (or any nut/seed butter)
  • Optional: chocolate chips, dried fruits, chopped nuts, or seeds

Instructions

  1. Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a mixing bowl, mash the bananas until smooth with no lumps.
  3. Stir in the peanut butter until well combined.
  4. Fold in the rolled oats until a sticky dough forms.
  5. Scoop tablespoon-sized portions onto the baking sheet and flatten each cookie slightly.
  6. Bake for 12–15 minutes, or until golden brown and firm to the touch.

  • Natural, unsweetened peanut butter gives the best flavor without added sugars.
  • Add-ins like chocolate chips or cinnamon can enhance flavor and texture.
  • Use gluten-free oats or nut-free butters to suit dietary needs.
  • Store in an airtight container for 5 days or freeze for up to 3 months.
