Can you freeze rice krispie treats?

Yes, these treats can be frozen. I prefer to flash freeze cut into squares for 1-2 hours and then place in a freezer container.

Another method is to wrap in parchment paper and freeze immediately in a container or bag.

They can be frozen up to 6 months. The texture may change a little bit once frozen but they will still be yummy.

Tips for Lucky Charm Rice Krispie Treats:

  • Don’t overcook the marshmallows. Be very careful to only cook the marshmallows as directed. Overcooking the marshmallows will make the mixture very sticky and it will be difficult to set.
  • Combine ingredients together quickly. You want to combine everything together before the marshmallows set.
  • Top with extra marshmallows. The treats are even more festive with Lucky Charms Marshmallows. Don’t forget to reserve some for the top. They need to be pressed into the top before it sets or they will not stick.
  • Press the mixture with parchment paper. The mixture can be very sticky. Spray wax paper with cooking spray or a spatula. Then press into the mixture to even it out.
  • Allow to set. The mixture needs time to set before cutting. Attempting this too soon will result in a sticky mess.

Variations:

  • Food Coloring. The green food coloring makes it festive but you can omit it if you prefer. It will still look great with the Lucky Charms Marshmallows.
  • Sprinkles. Rainbow sprinkles are perfect to add to this dessert for St. Patrick’s Day. Add a handful to the top before it sets once in the pan.
  • Chocolate cereal. Chocolate fans might like to try a chocolate version of this dessert. Substitute Cocoa Krispies and Chocolate Lucky Charms for tons of chocolate flavor.
