Ingredients

  • 2 ripe bananas 8 oz (225g) in total
  • ¼ cup (60 g) peanut butter or almond butter

Instructions

  • Preheat the oven to 350°F (180°C) and line a 7 x 7 inch (15 x 15 cm) brownie pan with parchment paper.
  • In a large bowl, mash the ripe bananas. Add the peanut butter, vanilla extract (if using), and a pinch of salt. For sweeter bars, stir in 2 to 4 tablespoons of maple syrup or honey. Mix until smooth.

Notes

Ingredient Notes

  • Sweetener: Ripe bananas add plenty of natural sweetness. For sweeter banana oat squares, add a couple tablespoons of maple syrup or honey - taste the dough and adjust with sweetener if it is necessary.
  • Gluten-free: Use certified gluten-free rolled oats.
  • Protein powder: For high protein banana bars, replace ½ cup (50g) of oats with protein powder. I recommend vanilla flavor protein powder.

Storage Notes

  • To store: Store leftovers in an airtight container in the fridge for up to 5 days.
  • To freeze: Place in zipper bags and freeze for up to 4 months.
  • To reheat: Remove the bars from the freezer, then warm up in hot oven or in the microwave.
