Ingredients

Instructions

  1. Step 1: Line an 8x8-inch square pan with parchment paper, leaving an overhang for easy removal.
  2. Step 2: In a large microwave-safe bowl, combine 1 cup smooth peanut butter and 1/2 cup unsalted butter. Microwave for 1 minute, stirring halfway, until melted and smooth.
  3. Step 3: Stir in 2 cups graham cracker crumbs and 1 1/2 cups powdered sugar until fully combined into a thick dough-like mixture.
  4. Step 4: Press the peanut butter mixture evenly into the prepared pan to form the base layer.
  5. Step 5: In a clean microwave-safe bowl, melt 1 1/2 cups semi-sweet chocolate chips in 30-second intervals, stirring between each, until smooth.
  6. Step 6: Pour the melted chocolate over the peanut butter base and spread evenly with a spatula.
  7. Step 7: Refrigerate the bars for at least 2 hours until the chocolate is firm. Use the parchment paper to lift the bars out and cut into 16 squares before serving.
