Description

These Banana Oatmeal Peanut Butter Bars are a wholesome, naturally sweet treat made with just a handful of ingredients. Perfect for breakfast or snack time, they’re chewy, satisfying, and totally customizable with optional chocolate chips


Ingredients

Scale
  • 2 very large, extra ripe bananas (the black-speckled kind)
  • ½ cup natural peanut butter (or sunflower seed butter for nut-free)
  • 1 tablespoon honey or coconut sugar (optional, for added sweetness)
  • 2 cups quick-cooking oats (not instant)
  • ⅛ tablespoon salt
  • ¼ cup chocolate chips, plus extra for topping (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line or grease an 8×8 inch baking pan, ideally using parchment paper with overhang for easy removal.
  2. Mash the bananas in a medium mixing bowl until smooth with just a few small lumps.
  3. Stir in the peanut butter, optional sweetener, and salt. Mix until smooth and creamy.
  4. Add the oats and chocolate chips (if using). Fold with a spatula until fully combined. The batter will be thick and sticky.
  5. Spread the mixture into the prepared pan, pressing it into an even layer. Sprinkle extra chocolate chips on top if desired.
  6. Bake for 18–25 minutes, or until the edges are golden and the center is set. Let cool before slicing into bars.

Notes

  • Microwave unpeeled bananas for 30 seconds to quickly ripen.
  • Use old-fashioned oats for a chewier texture, or pulse quick oats for softer bars.
  • Freeze individual bars with parchment in between for grab-and-go snacks.
