Ingredients
  

Base Ingredients

2 medium ripe bananas, well spotted

1 cup rolled oats (or quick oats)

Choose Your Third Ingredient

¼ cup chocolate chips (or peanut butter, or chopped walnuts)

Optional Add-Ins

1 teaspoon ground cinnamon

Pinch of salt

Method
 

  1. Preheat the oven — Preheat to 350°F and line a baking sheet with parchment paper.
    Mash the bananas — In a large bowl, mash the ripe bananas with a fork until mostly smooth, with a few small lumps remaining.
    Stir in the oats — Add the oats and your chosen third ingredient (chocolate chips, peanut butter, or walnuts), stirring until well combined.
    Let the batter rest — Let the mixture sit for a few minutes so the oats can absorb moisture from the banana.
    Scoop and shape — Scoop heaping tablespoon-sized portions onto the prepared baking sheet, flattening each slightly since these cookies won't spread on their own.
    Bake — Bake for 15 minutes, until the edges look golden and the tops feel set.
    Cool and serve — Let cool slightly on the baking sheet before transferring and serving.

Notes

  • Use the ripest, spottiest bananas you can find — they provide all the natural sweetness in this recipe.
  • Letting the batter rest for a few minutes before baking helps the cookies hold their shape.
  • Store in an airtight container in the fridge for up to 4-5 days, or freeze baked cookies or raw dough for up to 3 months.
  • For gluten-free cookies, use certified gluten-free oats.
