If you love classic marshmallow cereal bars, you are going to adore this version. By swapping out plain rice cereal for Lucky Charms, you get a beautiful pop of color and extra sweetness from those iconic marshmallows in every single bite.

These bars are a hit at birthday parties and school events because they look so bright and festive. My best tip is to press the mixture into your pan very gently. If you push too hard, the bars can become a bit tough instead of staying soft and chewy.

Ingredients

  • 1/4 cup unsalted butter
  • 10 ounces mini marshmallows
  • 6 cups Lucky Charms cereal
  • 1/4 teaspoon vanilla extract

Instructions

  1. 1

    Prepare a 9 by 9 inch baking pan by lining it with parchment paper or greasing it lightly with butter.

  2. 2

    Melt the butter in a large pot over low heat until it is fully liquid.

  3. 3

    Add the marshmallows to the pot and stir constantly until they are completely melted and smooth.

  4. 4

    Remove the pot from the heat and stir in the vanilla extract.

  5. 5

    Quickly fold in the cereal, stirring just enough to coat the pieces in the marshmallow mixture without crushing the cereal too much.

  6. 6

    Transfer the mixture to your prepared pan and use a buttered spatula to gently spread it out into an even layer.

  7. 7

    Let the bars sit at room temperature for at least 30 minutes to firm up before you cut them into squares.

💡 Tips

Store these treats in an airtight container at room temperature for up to three days. For a fun serving idea, cut them into small triangles or use cookie cutters to create festive shapes.
