Eight Lucky Charm Marshmallow Treats on a Serving Platter with a Cold Glass of Milk

“These Lucky Charm treats were so easy to make, my daughter made them mostly by herself! They turned out so perfect – soft, chewy, and with just the right amount of sweetness. Be careful not to over-stir in the cereal or the cereal marshmallows can start to melt.” โ€” Haley, busy mom of two and passionate home cook and baker.

Ingredient Notes

You only need 4 inexpensive ingredients to whip together a batch of Lucky Charms Treats. See the printable recipe card below for measurements!

  • Lucky Charms Cereal: The star of the show, but you could make these bars with any cereal.
  • Mini Marshmallows: You can use large marshmallows, but they will take longer to melt. Use soft and fresh marshmallows so the bars turn out soft and chewy, old marshmallows tend to be stale and dry.
  • Butter: If you choose to use salted butter, only add an additional 1/4 teaspoon of salt. For an added depth of flavor, you can brown the butter for a slightly nutty flavor. Follow these directions for how to brown butter before adding in the marshmallows.
  • Salt: A pinch of salt is optional, but it helps to balance the sweetness.

How to Make Lucky Charms Rice Krispie Treats

You’re going to love just how quick and easy they are to make โ€” with no oven required! I like to line my pan with parchment paper for easy removal and cleaner cutting. A little butter or non-stick spray will help hold it in place. For a more decorative finish, I always set aside a few of the colorful Lucky Charms marshmallows to press into the top of the bars after I add them to the pan.

Below is a quick step-by-step recipe overview, please scroll down to the printable recipe card for full instructions.

Melt the butter, then add salt and marshmallows.

Chef’s Tips & Variations

  • Press Gently: Avoid packing the mixture too tightly into the pan. Lightly press it in with buttered hands or a greased spatula to keep the treats soft and airy.
  • Even More Marshmallows: For an ultra-gooey texture, stir in up to 3 extra cups of mini marshmallows after melting the first batch. This creates soft, pillowy pockets in each bite.
  • Extra Thick: For thick, bakery-style bars, double the recipe OR press the mixture into a smaller pan (like an 8×8-inch pan instead of a 9×13).
  • Fun Shapes: Instead of squares, use cookie cutters to make fun shapes like hearts, stars, or circles for special occasions. Insert a lollipop stick into each one for a fun, handheld versionโ€”great for kidsโ€™ parties!
