How to Make Giant Lucky Charms Treats
Step 1: Prepare the Pan
Lightly coat a loaf pan with cooking spray.
If you’d rather make traditional cereal bars instead of giant ones, you can use an 8×8-inch or 9×13-inch baking dish.
Set the prepared pan aside.
Step 2: Melt the Butter
In a large saucepan over medium-low heat, melt the butter completely.
Avoid using high heat, which can make the marshmallow mixture tougher.
Step 3: Melt the Marshmallows
Add the mini marshmallows to the melted butter.
Stir constantly until the marshmallows are completely melted and smooth.
The mixture should be glossy with no lumps remaining.
Step 4: Stir in the Cereal
Gradually add the Lucky Charms cereal a few cups at a time.
Fold gently until every piece of cereal is coated in the marshmallow mixture.
Try not to crush the cereal while stirring.
Step 5: Fill the Pan
Transfer the cereal mixture into the prepared loaf pan.
Using a lightly buttered spatula or a piece of wax paper, gently press the mixture into the pan.
Press just enough to remove air pockets without compacting the treats too tightly.
Step 6: Cool
Allow the treats to cool completely at room temperature.
Once firm, carefully remove them from the pan.
Step 7: Slice
Slice each loaf into one oversized cereal bar or cut into smaller portions if preferred.
Serve immediately or wrap individually for later.

Frequently Asked Questions
Why are my cereal treats hard?
Using too much heat or pressing the mixture too firmly into the pan can make marshmallow treats dense. Cook over low heat and press gently for the softest texture.
Can I use large marshmallows?
Yes! Large marshmallows work just as well. They’ll simply take a little longer to melt.
Can I make regular-sized cereal bars?
Absolutely. Instead of using loaf pans, spread the mixture into an 8×8-inch or 9×13-inch pan and cut into squares once cooled.
Can I freeze Lucky Charms Treats?
While they can be frozen, they’re best enjoyed fresh. Freezing can slightly change the texture of the marshmallows.
