Ingredients

Scale

Wet Ingredients

  • 3 very ripe bananas
  • 1/4 cup smooth (natural) peanut butter
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 1/4 cup instant or quick cooking oats
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking powder

Add-ins

  • 1/2 cup chocolate chips

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line or grease an 8×8 inch baking pan to prevent sticking.
  2. Mash Bananas: In a large bowl, mash the very ripe bananas thoroughly with a fork until smooth and slightly creamy.
  3. Mix Wet Ingredients: Add the smooth peanut butter and vanilla extract to the mashed bananas. Stir well to combine until the mixture is uniform.
  4. Combine Dry Ingredients: In a separate bowl, mix the instant or quick cooking oats with the salt and baking powder thoroughly.
  5. Combine Wet and Dry Mixtures: Add the oat mixture to the banana and peanut butter mixture. Stir until just combined and the batter is thick but cohesive.
  6. Add Chocolate Chips: Gently fold in the chocolate chips, distributing them evenly throughout the batter.
  7. Transfer and Bake: Pour the batter into the prepared baking pan and spread it out evenly. Bake in the preheated oven for about 20-25 minutes or until the edges are golden and a toothpick inserted into the center comes out clean.
  8. Cool and Slice: Allow the bars to cool completely in the pan before cutting into squares to ensure they hold together well.

Notes

  • Use very ripe bananas for natural sweetness and moisture.
  • Natural peanut butter works best to keep the flavors rich and smooth.
  • Instant or quick cooking oats provide a better texture; rolled oats can be used but will produce a denser bar.
  • Chocolate chips add a delightful sweetness but can be omitted or replaced with nuts for a healthier option.
  • Store bars in an airtight container at room temperature for up to 3 days or refrigerate to keep longer.
