Step 1

Prepare Your Pan: Lightly grease an 8x8-inch or 9x13-inch baking dish (depending on desired thickness) with butter or nonstick spray. For easy removal, line the dish with parchment paper.

Step 2

Melt the Butter: In a large saucepan, melt the butter over medium heat until completely smooth. Stir frequently to prevent browning.

Step 3

Melt the Marshmallows: Add the mini marshmallows to the melted butter and stir constantly until the marshmallows are fully melted and smooth. Remove the pan from heat and stir in the vanilla extract and salt.

Step 4

Combine with Lucky Charms: Pour the Lucky Charms cereal into the marshmallow mixture and gently fold until all the cereal is evenly coated.

Step 5

Transfer to Pan: Pour the mixture into the prepared pan and press it down gently using a greased spatula or buttered hands to prevent sticking. Be careful not to pack it too tightly, as this can make the treats dense.

Step 6

Decorate (Optional): Sprinkle extra Lucky Charms marshmallows or colorful sprinkles on top, pressing them lightly into the surface.

Step 7

Cool and Slice: Let the treats cool at room temperature for about 30 minutes, or until firm. Slice into squares or bars and serve.
