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

Additional

  • 1/2 cup chocolate chips (divided: 1/3 cup for batter, 1/6 cup for topping)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a loaf pan or line it with parchment paper for easy removal of the bars after baking.
  2. Mash Bananas and Mix Wet Ingredients: In a large bowl, mash the ripe bananas until almost smooth. Add the smooth peanut butter and vanilla extract, stirring well to combine into a uniform mixture.
  3. Add Dry Ingredients: Incorporate the instant or quick oats, salt, and baking powder into the wet mixture. Stir until everything is evenly combined. Fold in about 1/3 cup of the chocolate chips gently to distribute throughout the batter.
  4. Pour Batter and Add Topping: Transfer the batter into the prepared loaf pan. Use a spoon or spatula to smooth out the top evenly. Sprinkle the remaining chocolate chips over the top for added texture and flavor.
  5. Bake: Place the loaf pan in the oven and bake for 25 to 30 minutes, or until a knife inserted in the center comes out clean, indicating the bars are fully cooked.
  6. Cool and Serve: Remove the pan from the oven and allow the bars to cool completely before slicing into 6 to 8 bars. This helps the bars set and makes slicing easier.

Notes

  • Use very ripe bananas for maximum sweetness and moisture.
  • Natural or smooth peanut butter is best for easy mixing and smooth texture.
  • Instant or quick oats are recommended for the best texture, but rolled oats can be substituted if processed slightly.
  • Chocolate chips can be omitted or replaced with nuts or dried fruit for variation.
  • Store bars in an airtight container at room temperature for up to 3 days, or refrigerate up to a week.
