Make these simple, layered bars with a chewy oat base, creamy peanut butter filling, and a rich chocolate topping. No oven required.

Ingredients

Scale
  • 1 1/2 cups rolled oats
  • 1/2 cup peanut butter
  • 1/2 cup butter, melted
  • 1 cup powdered sugar
  • 1/2 cup semi-sweet chocolate chips
  • 1/4 cup peanut butter (for the middle layer)
  • 1 tablespoon coconut oil

Instructions

  1. Line an 8×8 inch pan with parchment paper, leaving an overhang for easy removal.
  2. In a medium bowl, mix the rolled oats, 1/2 cup peanut butter, melted butter, and powdered sugar until fully combined.
  3. Press this mixture firmly and evenly into the bottom of the prepared pan.
  4. In a separate small bowl, combine the 1/4 cup peanut butter and coconut oil. Microwave for 20-30 seconds until soft, then stir until smooth. Spread this layer evenly over the oat base.
  5. In a third small bowl, melt the chocolate chips with the remaining 1 tablespoon of coconut oil (or use the microwave in 20-second intervals). Stir until smooth.
  6. Pour the melted chocolate over the peanut butter layer and spread it to cover completely.
  7. Refrigerate the bars for at least 2 hours, or until the chocolate topping is firm.
  8. Lift the bars out of the pan using the parchment paper overhang and cut into squares.

Notes

  • For a firmer bar, chill the bars for 4 hours or overnight before slicing.
  • If you want a gluten-free version, use certified gluten-free rolled oats.
  • Store leftovers in an airtight container in the refrigerator for up to one week.
