  5. Step 5: In another microwave-safe bowl, melt 1 1/2 cups semi-sweet chocolate chips in 30-second bursts, stirring until smooth.
  6. Step 6: Pour the melted chocolate over the peanut butter layer and spread evenly with a spatula.
  7. Step 7: Sprinkle 1/4 cup chopped roasted peanuts over the top while the chocolate is still warm.
  8. Step 8: Refrigerate the bars for at least 2 hours until firm.
  9. Step 9: Use the parchment paper overhang to lift the bars out of the pan and cut into 12 squares before serving.
