Pro Tips for Success:

  • Chill treats first: Pop your Rice Krispies in the fridge for 10 minutes to make shaping easier and less sticky.

  • Use a ruler as a guide: Place a real ruler next to your treat while piping for more realistic tick marks.

  • Try different colors: Make “fun rulers” using colored candy melts for a playful twist.

  • Add names for personalization: Pipe a child’s name or grade on the back for party favors or place settings.

  • Use kitchen tweezers: Helps fix any crooked lines or small mistakes while the candy is still soft.

  • Let kids help: Little ones can help flatten and shape the treats—it’s a fun family activity.

  • Make ahead: These store well in an airtight container for 2–3 days, making prep a breeze.
