Ingredients

  • 6 Tablespoons salted butter
  • 16 ounces marshmallows
  • 4 cups Lucky Charms cereal
  • 3 cups Rice Krispies cereal
  • Pinch of salt (optional)

Instructions

  • Line a 9x9 (or 9x13-inch for thinner squares) baking dish with a parchment paper sling or lightly spray with cooking spray.
  • Heat butter in a large pot over medium-low heat on the stovetop until melted. Keep the butter wrapper for later! Add the marshmallows and continue to cook over low to medium-low heat, stirring frequently, until mostly melted. Resist the urge to increase the heat to speed up the process. This can also be done by heating the butter and marshmallows in the microwave for 2-3 minutes until melted.

  • Remove the melted marshmallow mixture from the heat and stir in the cereal and salt just until evenly coated.

  • Gently pat the mixture into the prepared baking dish using the buttered side of the reserved butter wrapper. The key is to press them just enough to hold together and smooth out the top, but not to compact the krispie treats into the pan. Press a few extra colorful marshmallow pieces into the tops of the treats for decoration, if desired.
  • Let set up for at least 30 minutes before cutting into squares with a sharp knife.

Notes

  • I like to use one 10-ounce bag mini marshmallows and 1/2 of a 12-ounce bag of large marshmallows.
  • You can easily double the recipe for a 9x13-inch pan of thick treats, or spread the recipe as written in a 9x13-inch pan for thinner treats.
  • These really are best the same day they are made, but you can keep them covered with plastic wrap in the pan for up to 4 days. You can also wrap individual squares with plastic wrap to throw them in lunchboxes for a fun St. Patrick's Day treat.
