Creating Lucky Charms Rice Crispy Treats is a simple process. Follow these steps for the best results:

1. Prepare the Pan: Grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking. Set it aside.
2. Melt Butter: In a large saucepan over low heat, melt the unsalted butter. Stir constantly to ensure it doesn’t burn.
3. Add Marshmallows: Once the butter is melted, add the mini marshmallows to the saucepan. Continue to stir until the marshmallows are completely melted and smooth.
4. Incorporate Vanilla: Stir in the vanilla extract and a pinch of salt until well combined.
5. Mix in Cereals: Remove the saucepan from heat. Carefully add both the Rice Crispy cereal and Lucky Charms cereal to the melted marshmallow mixture. Gently fold the cereals into the mixture until fully coated.
6. Transfer to Dish: Pour the mixture into the prepared baking dish. Use a spatula to press it down evenly and firmly. Be careful not to squish it too hard, as you want the treats to remain chewy.
7. Cool and Set: Allow the mixture to cool at room temperature for about 15-20 minutes or until set.
8. Cut into Squares: Once set, use a sharp knife to cut the treats into squares or rectangles.
9. Store: Keep any leftovers in an airtight container at room temperature for up to a week.
