Step 1: Prepare the Pan
Lightly grease a 9×9-inch baking dish or baking pan with cooking spray, or line it with a piece of parchment paper.
Set aside.
Step 2: Melt the Marshmallows
In a large pot or large saucepan, melt the butter over medium heat to low heat.
Once melted, add the mini marshmallows and stir continuously until smooth and fully melted.
Using fresh marshmallows gives you the best texture.
Step 3: Add the Cereal
Remove from heat and immediately stir in the Lucky Charms cereal.
Using a silicone spatula, gently fold the cereal mixture together until evenly coated in the melted marshmallows.
Step 4: Press Into the Pan
Transfer the Lucky Charms mixture into the prepared pan.
Use lightly greased wax paper or a spatula to gently press into an even layer. Don’t press too firmly or the bars can become dense instead of soft and chewy.
Step 5: Cool and Slice
Allow the bars to cool at room temperature for 30–45 minutes.
Once fully set, transfer to a cutting board and cut into squares.
