Equipment

  • Sauce pot
  • Rubber Spatula
  • Measuring Cups
  • 9x13 pan
  • parchment paper or cooking spray

Ingredients

  • 1 stick butter
  • 1 bag mini marshmallows 10 oz
  • 2 cups Rice Krispies
  • 3 cups Lucky Charms
  • ¾ cup Lucky Charms marshmallows and cereal separated
  • pinch salt

Instructions

  • Start by measuring ¾ cup of Lucky Charms and separating the marshmallows and cereal so it’s ready to pour in when needed.
  • Heat a large pot on medium-low heat. Once warm, add the butter and let it melt. Stir continuously so it does not burn.
  • Once butter has melted, add the marshmallows and continue stirring until they are 75% melted. Turn off the stove and remove the pan from heat.

  • Pour in Rice Krispies 3 cups Lucky Charms, the Lucky Charms cereal from the separated portion, and salt. Stir together. Do not over stir or marshmallows will become overly stiff.

Notes

I prefer to store Rice Krispie Treats in the refrigerator, but the counter is also fine. They keep for up to 5 days or freeze for up to 3 months. Just note that the longer they sit, the less crisp they will hold. Make the day of serving for optimal freshness. 
Spraying a pizza cutter or large knife works great for cutting Rice Krispie treats. Be sure the bars are completely cooled and set before attempting to cut them.
You do not HAVE to separate the Lucky Charms cereal and marshmallows, but the marshmallows on top do make them more visually appealing.
This recipe has not been tested with off brand Lucky Charms or Rice Krispies, so I cannot tell you if they'll turn out. Just know that might change the texture or flavor!
