Ingredients

Scale

Base 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 the oven: Set your oven to 350°F (175°C) to ensure it reaches the perfect temperature for baking your cookies evenly.
  2. Mash the bananas: Peel and place the ripe bananas in a medium bowl. Use a potato masher or fork to mash them thoroughly until mostly smooth with only small chunks remaining.
  3. Combine ingredients: Stir in the rolled oats and ground cinnamon with the mashed bananas. Let the mixture sit for a few minutes so the oats can absorb the moisture. If the batter feels too wet or thin, add 1-2 tablespoons more oats to achieve a firmer consistency.
  4. Prepare the baking tray: Line a baking tray with parchment paper or a silicone baking mat to prevent sticking, which is crucial since these cookies do not spread during baking.
  5. Shape the cookies: Drop spoonfuls of the batter onto the prepared tray. Use your fingers to shape the cookies to your desired width and height, around 3 inches wide. This recipe yields approximately eight medium-sized cookies.
  6. Add optional toppings: If you wish, sprinkle additional toppings such as nuts, seeds, or dried fruit on the cookies before baking for extra flavor and texture.
  7. Bake: Place the cookies in the oven and bake them for 17 minutes. If making smaller cookies, reduce the baking time slightly; for larger cookies, increase the time by a few minutes.
  8. Cool and serve: Remove the cookies from the oven and allow them to cool slightly on the tray before enjoying their soft, naturally sweet flavor.

Notes

  • If the batter is too wet, adding extra oats helps maintain structure.
  • Cookies do not spread, so shape them properly before baking.
  • Adjust baking time for cookie size: smaller cookies need less time, larger might need more.
  • Optional add-ins like nuts or chocolate chips can enhance flavor.
  • Store leftovers in an airtight container at room temperature for up to 2 days or refrigerate for up to a week.
