Ingredients

½ cup salted butter
1 10 oz bag mini marshmallows
1 tsp vanilla extract
6 cups Lucky Charms

Instructions

Add the butter to a Dutch oven or large pot and heat until completely melted. Add the marshmallows and vanilla stirring continuously over medium heat until smooth and fully melted.
Remove from heat and pour in the Lucky Charms cereal. Stir until everything is evenly coated.
Transfer the mixture into a parchment-lined 9x13 baking dish. Press it down evenly and smooth the top. Add extra marshmallows on top if desired.
Let cool completely until set, about an hour, then cut into even squares. Serve and enjoy.

Notes

Lightly grease your spatula or hands to prevent sticking while pressing the mixture into the pan.
Don’t press too firmly or the bars can become dense instead of soft and chewy.
Add extra Lucky Charms marshmallows on top for a bakery-style look.
Let the bars cool fully before cutting to get clean, even squares.
Store in an airtight container at room temperature for the best texture.
