How to Make Lucky Charms Rice Krispie Treats
Prepare a 9×9-inch pan by spraying it with butter cooking spray. Set aside.
In a large pot over medium heat, melt the butter. Use a rubber spatula to spread the butter up the sides of the pot to prevent sticking.
Add the mini marshmallows and stir over medium heat until completely melted. Then remove from the heat.

Add the Lucky Charms cereal and use the rubber spatula to stir until everything is evenly coated.

Pour the mixture into the prepared pan. Wet your hands, shake off the excess water, and gently press the mixture into the pan. Let it cool at room temperature for about 30 minutes.
Use the rubber spatula to loosen the treats from the pan, then cut them into squares. Enjoy!
