Notes

  • The Reese's candies and chocolates are totally optional. If you want to keep the Rice Krispie treats plain, you can leave them out completely.
  • If you are in a hurry, you can refrigerate the Rice Krispie treats before serving. Just cover and place in the refrigerator for 30 minutes to harden the chocolate topping
  • For maximum freshness, wait to cut into squares until right before serving
