Ingredients

Main ingredients

  • 2 large overripe bananas, thoroughly mashed The riper, the sweeter.
  • 1/3 cup creamy peanut butter Natural or regular; see notes.
  • 1/2 teaspoon vanilla extract
  • 1 3/4 cups old-fashioned rolled oats Do not use instant for the best texture.
  • 1/4 cup sugar-free chocolate chips or cacao nibs

Instructions

Preparation

  • Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
  • In a large bowl, mash the bananas until mostly smooth.
  • Add the peanut butter and vanilla, stirring until the mixture is homogeneous.
  • Gradually add the rolled oats and mix until evenly combined and scoopable.
  • Fold in the sugar-free chocolate chips or cacao nibs.
  • Wet your hands slightly to prevent sticking, then scoop walnut-sized portions and roll into balls.
  • Place cookies 1½ inches apart on the prepared sheet and gently press each to flatten.

Baking

  • Bake for 10–12 minutes, until edges are lightly golden. Cookies won’t spread much, so shape them as desired before baking.
  • Let cool on the baking sheet for 5 minutes, then transfer to a wire rack to finish cooling.

Notes

Store cookies in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days. Freeze baked cookies to keep for up to 3 months. Ideal for breakfast, snacks, or as a healthy dessert.
