Ingredients

Instructions

  1. Step 1: In a large mixing bowl, combine 2 cups rolled oats, 1/2 cup mashed ripe banana, 1 cup natural peanut butter, 1/4 cup honey, 1 tsp vanilla extract, and 1/4 tsp salt. Stir thoroughly until all ingredients are well incorporated.
  2. Step 2: If using, fold in 1/4 cup mini chocolate chips evenly throughout the mixture.
  3. Step 3: Line an 8x8 inch square baking pan with parchment paper. Transfer the mixture into the pan and press down firmly with a spatula or your hands to create an even, compact layer.
  4. Step 4: Refrigerate for at least 2 hours until bars are firm enough to cut.
  5. Step 5: Remove from fridge, lift bars out using parchment paper, and cut into 12 equal bars. Store in an airtight container in the fridge for up to one week.
