Ingredients

Scale

Main Ingredients

  • 2 ripe and spotty bananas, mashed (about 200g)
  • 1 cup rolled oats (old fashioned or quick cooking)
  • 1 teaspoon ground cinnamon

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the cookies.
  2. Mash Bananas: Peel and mash the ripe bananas in a medium bowl using a potato masher or fork until well mashed with only small chunks remaining.
  3. Mix Ingredients: Stir in the rolled oats and ground cinnamon into the mashed bananas. Let the mixture sit for a few minutes to allow the oats to absorb moisture. If the batter seems too wet or thin, add an additional 1-2 tablespoons of oats.
  4. Prepare Baking Tray: Line a baking tray with parchment paper or a silicone baking mat to prevent the cookies from sticking while baking.
  5. Form Cookies: Drop spoonfuls of batter onto the baking sheet and shape them with your fingers into the desired width and height. Keep in mind the cookies will not spread while baking. This recipe yields about eight medium-sized cookies approximately 3 inches wide.
  6. Add Optional Toppings (Optional): If desired, sprinkle toppings such as nuts, chocolate chips, or dried fruit on the shaped cookies before baking.
  7. Bake: Bake the cookies in the preheated oven for 17 minutes or until they are set.
  8. Cool and Serve: Remove the cookies from the oven and allow them to cool slightly on the baking tray before enjoying.

Notes

  • For smaller cookies, reduce baking time to about 12-15 minutes.
  • For larger or thicker cookies, increase baking time slightly to 18-20 minutes, but monitor closely to prevent burning.
  • Ensure bananas are very ripe as they provide natural sweetness and moisture.
  • You can add mix-ins or toppings such as walnuts, chocolate chips, or raisins to customize your cookies.
  • Use rolled oats for best texture; instant oats may result in a different consistency.
