Ingredients
- 5 cups mini marshmallows
- 4 tablespoons butter
- 6 cups Lucky Charms cereal
Instructions
- In a large saucepan, melt the butter over low heat.
- Add the mini marshmallows and stir frequently until they’re completely melted and smooth.
- Remove the pan from heat and quickly stir in the Lucky Charms cereal until evenly coated.
- Spray a 9×13-inch baking pan with non-stick spray.
- Spoon the cereal mixture into the pan and gently spread it out using a spatula.
- Allow the treats to cool at room temperature for about 1 hour, or until set.
- Cut into squares or bars and serve.

Serving and Storage Tips
- Storage: Keep treats in an airtight container at room temperature for up to 3 days.
- Avoid refrigeration: Refrigerating them can make the marshmallows hard.
- Prevent sticking: Line your container with wax or parchment paper between layers.
- Softness trick: Place a slice of bread in the container to help retain moisture.
- Serving suggestion: Cut them into fun shapes using cookie cutters for parties.
- To-go idea: Wrap individual bars in plastic wrap for easy lunchbox or picnic snacks.
- Presentation: Drizzle melted chocolate or white chocolate for a polished finish.
- For a clean cut: Use a buttered or non-stick sprayed knife when slicing.
- Reheat tip: If they start to harden, microwave a piece for 5–7 seconds to soften.
- Freezing: Not recommended — it alters the chewy texture.

FAQs
- Can I use large marshmallows instead of mini ones? Yes, about 40 large marshmallows equal 5 cups of mini marshmallows.
- Can I melt the marshmallows in the microwave? Yes, microwave butter and marshmallows in 30-second intervals, stirring each time.
- Why are my bars hard? They may have been cooked over high heat or pressed too firmly into the pan.
- Can I use margarine instead of butter? Yes, though butter gives a richer flavor.
- Are Lucky Charms gluten-free? Most are, but check the packaging to confirm.
- Can I add mix-ins like chocolate chips or nuts? Definitely! Add them once the marshmallow mixture has cooled slightly.
- How do I keep the bars from sticking to my hands? Rub butter or spray oil on your hands before pressing them into the pan.
- Can I make these ahead of time? Yes, prepare them a day in advance and store in an airtight container.
- How do I make them extra soft and gooey? Reduce the cereal to 5 cups or add an extra ½ cup marshmallows.
- Can I freeze Lucky Charms treats? Not recommended — freezing makes them brittle and loses texture.
