Ingredients Equipment Method Notes

Ingredients
  

  • 6 cups Rice Krispies cereal
  • 10 oz bag of mini marshmallows
  • 4 tablespoons unsalted butter
  • 1 teaspoon pure vanilla extract
  • 1/4 teaspoon fine sea salt
  • 2 cups Lucky Charms cereal marshmallows separated
  • 1 1/2 cups Lucky Charms cereal oat pieces separated

Equipment

  • 9x13 inch baking pan
  • Large pot or Dutch oven
  • Sturdy silicone spatula
  • Measuring cups
  • Measuring spoons

Method
 

  1. Prep your station: Lightly grease a 9x13 inch baking pan with butter or non-stick spray. Measure and separate the Lucky Charms marshmallows and oat pieces. Have all other ingredients ready.
  2. Melt the foundation: In a large pot or Dutch oven, melt the butter over low heat. Add the mini marshmallows and salt. Stir constantly until completely smooth and melted.
  3. Combine and cool: Remove the pot from heat. Stir in the vanilla extract. Quickly add the Rice Krispies and the reserved Lucky Charms oat pieces. Fold and stir until all cereal is thoroughly coated.
  4. Fold in the magic: Let the mixture cool in the pot for about 90 seconds. Gently fold in the reserved Lucky Charms marshmallows until just distributed.
  5. Press and set: Transfer the mixture to the prepared pan. Lightly grease your hands or spatula and press the mixture evenly and firmly into the pan. Let cool completely at room temperature for 1-2 hours before slicing into squares.

Notes

For best results, use low heat to melt the marshmallows to prevent burning. Cooling the mixture slightly before adding the colorful marshmallows preserves their shape and color. Press firmly but do not over-compact for a light, snappy texture. Store in an airtight container at room temperature for up to 3 days. Variations: brown the butter first, drizzle with white chocolate, fold in sprinkles, or add 1/4 cup of peanut butter to the melted marshmallow mixture.
