Ingredients Equipment Method Notes

Ingredients
  

Bars
  • 3 large ripe bananas mashed (about 1 1/4 cups)
  • 1 cup creamy natural peanut butter
  • 1 1/2 cups rolled oats
  • 1/4 cup maple syrup or honey

Equipment

  • 8x8 inch baking pan
  • Parchment Paper
  • Mixing bowl
  • Spatula

Method
 

  1. Preheat the oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper.
  2. In a medium mixing bowl, mash the ripe bananas until mostly smooth and creamy.
  3. Add the creamy peanut butter to the mashed bananas and stir until fully combined.
  4. Add the rolled oats and maple syrup (or honey). Mix until a thick, even batter forms and no dry oats remain.
  5. Transfer the batter to the prepared pan and spread it out evenly with a spatula, pressing gently into the corners.
  6. Bake for 20–25 minutes, or until the edges are lightly golden and the center is just set.
  7. Allow the bars to cool completely in the pan, then lift out using the parchment and slice into 9 bars.

Notes

For extra flavor, sprinkle a pinch of flaky sea salt on top before baking or fold in a handful of dark chocolate chips. These bars firm up as they cool and are perfect for meal prep.
