Ingredients

CEREAL BARS:

  • 2 cups Cheerios cereal (You can use plain ones or honey nut flavor)
  • 2 cups Lucky Charms cereal (You can sub with your favorite healthier marshmallow-infused cereal)
  • 1 (7.5 oz) jar marshmallow fluff
  • 1 teaspoon vanilla extract
  • ½ teaspoon sea salt
  • ¼ cup rainbow sprinkles
  • Pinch of ground cinnamon

TOPPING:

  • Rainbow sprinkles (Just enough to cover the tops)

Instructions

  • Line a 9x9 baking pan with foil or parchment paper. NOTE: Be sure to coat the foil paper with a bit of spray if not using non-stick foil.

TO MAKE THE CEREAL BARS:

  • In a bowl, add the cereals along with the marshmallow fluff, vanilla, salt, sprinkles, and pinch of cinnamon, stirring everything together with a rubber spatula or wooden spoon. NOTE: I found it easier to work with my hands by wearing gloves to ensure that everything gets stirred together well.
  • Press the mixture into the prepped baking pan until even. Sprinkle remaining rainbow sprinkles atop bars and lightly press down. Cover with plastic wrap or foil and let it chill in the refrigerator for about 30 minutes or so.
  • Cut into bars and serve for a not too sweet treat!
  • Bon Appetit!

Notes

STORAGE: Leftover cereal bars can be tightly sealed and stored in the fridge for up to 1 week. Just know that the longer they stay in the fridge, the harder they get due to moisture being removed during chilling.
