Prep Time 5 minutes
Cook Time 10 minutes
Setting time 2 hours


  • 4 tbsp butter
  • 7 ½ cups mini marshmallows
  • 5 cups Lucky Charm cereal
  • rainbow sprinkles - opt


  • Grease a 9x13 pan with butter. Set aside.
  • In a large saucepan or shallow stockpot (non-stick preferably) melt the butter over low heat.
  • Once the butter is melted, add in 5 cups of the marshmallows, stirring over low heat until they are completely melted and blended with the butter.
  • Then add in the remaining marshmallows and stir until they are partially melted.
  • Remove from heat and fold in the Lucky Charm cereal until evenly coated with the marshmallow mixture.
  • Transfer to the prepared pan and press gently into an even layer. You can use a rubber spatula that has been sprayed with oil or non-stick spray. I find that just wetting my hands and pressing lightly works best & the moisture keeps most of the marshmallows from sticking to my hands.
  • Add sprinkles if desired and pick out any shaped marshmallows from the cereal to add to the tops. Press in gently.
  • Let the bars sit at room temperature for at least 2 hours before cutting into squares or rectangles.
  • Store in an airtight container with small pieces of parchment paper in between each one to keep them from sticking to each other.
