Instructions

1. Grease a 9 x 9 pan with cooking spray and set aside.
2. In a large pot over medium heat, melt the butter.
3. Add the marshmallows and salt and stir with a rubber spatula, scraping down the sides to make sure the marshmallows do not burn. As soon as the marshmallows are melted, remove from the heat immediately.
4. Add the Lucky Charms cereal, folding to coat the cereal completely.
5. Spoon the mixture into the prepared pan, pressing down into an even layer.*
6. Place in the fridge to set for at least 20 minutes. Once set, use a sharp knife to cut the Rice Krispie treats into 12 rectangles.
