A healthy cookie substitute

Preheat oven to 360°F. Place the peeled banana into a bowl and mash thoroughly with a fork until smooth and paste-like. Add the peanut butter or Nutella and stir until evenly combined. Mix in the oats and any optional add-ins such as chocolate chips or nuts. Scoop spoonfuls of the mixture onto a baking tray. The cookies do not need to be perfectly shaped. Bake for approximately 20 to 25 minutes or until the edges are crispy and the centers remain soft and warm. Remove from oven and allow to cool slightly before serving.
