  • 4 tablespoons unsalted butter
  • 1 10- ounce bag of mini marshmallows
  • 6 to 7 cups crisped rice cereal
  • 2 cups lucky charms marshmallows (or as many as you can find in the bag!


  • Line a 9x9-inch baking dish with parchment paper or spray it with nonstick spray. You can also use a 9x13 inch baking dish, the squares just won't be as thick!
  • In a large pot, melt the butter over low heat. Once the butter is melted and even a little browned, stir in the mini marshmallows. Stir until the mixture is creamy and the marshmallows have melted.
  • Turn off the heat and fold in the rice krispies. Completely mix until all the rice cereal is mixed in. Stir in 1 cup of the lucky charms marshmallows and fold them in for a few minutes. Press the mixture into the dish. I like to press it down with a piece of parchment paper so it gets super smooth on top and it doesn't stick to the spoon. Then I press the remaining lucky charm marshmallows into the top! Let them set for about an hour. Slice into squares and serve!
