Ingredients

  • 5 cups Lucky Charms Cereal (plus extra marshmallows for topping)
  • 4 cups Rice Krispies Cereal
  • 1 (10.5 oz) bag mini marshmallows
  • 5 teaspoons salted butter
  • Green gel food coloring (optional)

Instructions

  • Butter a 9x13” baking dish and set it aside.
  • In a microwave-safe bowl, melt the mini marshmallows in 20-second increments, stirring in between until partially melted.
  • In a separate microwave-safe bowl, melt the butter in 20-second increments until almost completely melted.
  • Add the melted butter to the marshmallows and microwave for another 20 seconds. Stir to combine.
  • Add a few drops of green gel food coloring to the mixture and stir well.
  • Add the Rice Krispies cereal and stir until evenly coated.
  • Gently fold in the Lucky Charms cereal until coated with the marshmallow mixture.
  • Using a buttered rubber spatula, press the mixture evenly into the prepared baking dish.
  • Top with extra marshmallows if desired.
  • Refrigerate for 30 minutes to set.
  • Once set, cut into 12 squares (or 8 larger squares for bigger treats).

Notes

  • Without food coloring: Skip the green food coloring for a classic look.
  • Add-ins: Customize the treat with mini chocolate chips, M&Ms, or other favorite cereals for variety.
  • Larger Treats: Cut into 8 squares for larger portions.
  • Storage: Store in an airtight container at room temperature for up to 3 days. Refrigerate for longer storage. Best enjoyed fresh but will last up to a week if stored properly.
