Ingredients and Variations

Cereal: Lucky Charms cereal pieces must be separated before preparing the recipe but that can be quick work if helpers volunteer! For a less sweet version, use half cereal and half crispy rice cereal. For a little bit of extra nutrition, mix in some old-fashioned oats or granola.

Marshmallows: Mini marshmallows will melt faster than regular-sized marshmallows, but they can be cut into smaller pieces before melting if needed. A 7-ounce jar of marshmallow crème (AKA ‘fluff) can be used instead of the marshmallows and will save lots of time!

Variations: Other kinds of crispy rice cereal can be used to make more no-bake desserts like chocolate cocoa pebbles, and Rice Chex (which are both gluten-free), however many cereal manufacturers offer gluten-free versions of the originals. Swirl in some peanut butter, mini M&M’s, sprinkles, or some caramel sauce if you like.

How to Make Lucky Charms Treats

  1. Melt butter and marshmallows, using either the stovetop or microwave directions (as per recipe below).
  2. Stir in the vanilla and cereal. Fold in Lucky Charms marshmallows, but reserve a handful for the top.
  3. Press mixture into pan, then sprinkle the reserved marshmallow charms over the top. Press everything down firmly.
  4. Cool, remove from pan, and cut into squares.

Pro Tip!

Once marshmallows are fully melted in Step 3, stir in a bit of green food coloring for a pop of Irish color!

Tips for Lucky Charms Marshmallow Treats

  • For a thick square that’s extra soft and chewy, use a smaller pan and layer the mixture with half of the cereal pressed into the pan and then sprinkle with half of the marshmallow charms. Top with remaining cereal and marshmallows.
  • To prevent sticky hands, use a sandwich bag as a glove and spray with pan release. Easy work and even easier cleanup! Or, grease the bottom of a measuring cup and use it to press the cereal into the pan. Hands that are moistened with a bit of water will help too!
  • Line the pan with aluminum foil so the treats are easy to remove once cooled. Use a metal pastry cutter or a damp sharp knife to cut perfect squares.
