Ingredients

Scale

🛒 Ingredients (makes about 12 bars):

  • 3 ripe bananas, mashed

  • 1 cup rolled oats

  • ½ cup peanut butter (smooth or crunchy)

  • Optional Add-ins:

    • ¼ cup chocolate chips or raisins

    • 1 teaspoon vanilla extract

    • ½ teaspoon cinnamon

    • Pinch of salt


Instructions

📝 Instructions:

Step 1: Preheat & Prepare Pan
Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease.

Step 2: Mix Wet Ingredients
In a large bowl, mash the bananas until smooth. Stir in peanut butter and vanilla (if using) until well combined.

Step 3: Add Dry Ingredients
Fold in oats, cinnamon, and a pinch of salt. Add chocolate chips or raisins if desired. Mix until evenly incorporated.

Step 4: Bake or Chill

  • Baked version: Spread mixture evenly in the pan and bake 20–25 minutes, until lightly golden and firm.

  • No-bake version: Press mixture firmly into the pan and chill in the fridge for at least 2 hours until set.

 

Step 5: Cut & Serve
Let cool slightly (or completely if baked) before slicing into bars. Store in an airtight container for up to 5 days in the fridge.

Notes

  • Baby-Friendly: Use smooth peanut butter, omit chocolate chips, and mash bananas extra fine.
  • Make-Ahead: Bars can be stored in the fridge or frozen for up to a month.
  • Texture: For chewier bars, add a few extra tablespoons of oats.
  • Variations: Swap peanut butter with almond or sunflower seed butter for nut-free options.
