Tips From Our Recipe Developer

  • Do not overheat your marshmallows. If marshmallows get too hot, the sugar will begin to caramelize, thereby making your too treats hard instead of gooey.
  • For best results, use fresh marshmallows.

Storage Tips

  • To Store: Your Fruit Loop Treat Bars will stay fresh for 2-3 days if stored in an airtight container at room temperature.
  • To Freeze: These bars can be wrapped and frozen in freezer-safe container for up to 1 month. To thaw, set the treats on your counter for at least 1 hour before unwrapping them.

Frequently Asked Questions

Can I make Cereal Bars in the microwave instead of on the stovetop?

Yes, you can easily make these bars using the microwave instead of the stovetop.

How should I store my Froot Loop Cereal Bars?

For best taste and softness, I like to store my Cereal Bars covered in plastic wrap at room temperature.
If you decide to refrigerate them, bring them to room temperature for at least 30 minutes before serving.
