Cook Lucky Charms Marshmallow Treats Like This

Ready to create your Lucky Charms Marshmallow Treats? Follow these simple steps:
Step 1: Prepare Your Baking Dish
Start by lining a 9×13-inch baking dish with parchment paper. This will make it easier to lift the treats out later, ensuring you don’t lose any of that deliciousness!
Step 2: Melt the Butter
In a large saucepan, melt the 1 cup of salted butter over low heat. Stir occasionally until completely melted and bubbly.
Step 3: Add the Marshmallows
Once the butter is melted, add the 8 cups of miniature marshmallows to the saucepan. Stir continuously until the marshmallows are completely melted and the mixture is smooth.
Step 4: Mix in the Lucky Charms
Remove the saucepan from the heat and quickly add the 10 cups of Lucky Charms cereal. Using your wooden spoon or spatula, fold the cereal into the marshmallow mixture until all the cereal is evenly coated.
Step 5: Transfer to the Baking Dish
Pour the mixture into the prepared baking dish. Use a spatula or your hands (dampened for easier handling) to press the mixture evenly into the dish, ensuring it’s compact.
Step 6: Let it Set
Allow the treats to cool at room temperature for about 30 minutes. This will help them firm up before you cut them into squares.
Step 7: Cut and Serve
Once cooled, lift the treats out of the baking dish using the parchment paper. Cut into squares or rectangles and serve. Enjoy the fun and flavor of your Lucky Charms Marshmallow Treats!

Can I use regular-sized marshmallows instead of miniature marshmallows?
Yes, you can! Just use about 4 cups of regular marshmallows, and be sure to melt them thoroughly.
What can I substitute for Lucky Charms cereal?
You can use any similar cereal that has a mix of sweet flavors and textures, such as Fruity Pebbles or Trix, but the iconic taste and look of Lucky Charms are hard to beat!
Can I add mix-ins like chocolate chips or nuts?
Absolutely! Feel free to fold in some chocolate chips, sprinkles, or even chopped nuts to enhance your treats further.
Why did my treats turn out too hard?
