These lucky charms rice krispie treats will make any day magical! Done in 30 minutes and made with just 4 ingredients, this recipe creates the perfect ratio of nostalgic Lucky Charms cereal to marshmallows producing extra gooey fun and festive rice krispie treats!

Ingredients

Units
  • 1 cup unsalted butter (2 sticks)
  • 2 (12-ounce) bags regular size marshmallows
  • 1 teaspoon vanilla extract
  • 12 cups Lucky Charms cereal

Instructions

  1. Line a 9x13 inch baking pan with parchment paper. Spray the parchment paper with a light mist of nonstick spray– this will prevent the rice krispie treats from sticking. Set aside. Reserve about 1.5 cups of marshmallows. Set side.
  2. Over medium heat, melt the butter in a large pot, stirring frequently to prevent the butter from burning. Once melted, stir in the marshmallows (excluding the reserved 1.5 cups) and vanilla extract until almost completely melted. Remove from the heat and add in the remaining marshmallows– give it a few stirs.
  3. Fold in the Lucky Charms cereal, making sure that all of the cereal is coated with the marshmallow mixture. The marshmallows that you added in just before the cereal won't be completely melted– thats just what we want!
  4. Transfer the mixture into the prepared baking pan. Using the butter wrapper or a lightly greased rubber spatula, gently spread the mixture into the pan. Do not pack it down with extreme force, just gently so it can set. Allow to set for about 20 minutes at room temperature.
  5. Lift the rice krispie treats as a whole out of the pan using the edges of the parchment paper. Cut into squares– I recommend 20 squares. Cover and store leftover rice krispie treats in an airtight container at room temperature for up to 3 days.

Notes

  1. Make Ahead & Freezing Instructions: These rice krispie treats can be made ahead of time for up to 3 days. Place in an airtight container, with sheets of parchment paper between the layers and store at room temperature. I don't recommend freezing these as the texture will not be the same after thawing.
  2. Lucky Charms Cereal: There are many brands of Lucky Charms now– feel free to use what you can find.
  3. Marshmallows: When picking out marshmallows, make sure you get the regular size marshmallows, not the miniature or extra-large.
  4. Want to make a smaller batch? You can easily reduce this recipe by half following the instructions above. Use an 8x8 inch baking pan instead.
