These Lucky Charms treats are gooey and loaded with marshmallows. They’re topped with a thin layer of buttercream and even more marshmallows!

I wanted to make a quick little treat for my family for St. Patrick’s Day using items I already had on hand. I took stock of my pantry and saw the Lucky Charms, marshmallows, and marshmallow creme. Bam, done, it was decided—I was going to make Lucky Charms Marshmallow Treats. My kids loved the treats and surprisingly the marshmallows in the cereal didn’t melt once it was added to the melted marshmallow mixture.

HOW DO YOU KEEP LUCKY CHARMS TREATS SOFT?

To keep these Lucky Charms Treats soft, you will need to do 2 things:

1. NEVER put them in the refrigerator. This will both harden them and suck a lot of the moisture out of them.
2. Keep the Lucky Charms Treats in an airtight container! I like this one or this one (I own both and use each one according to how many treats I have).

PRO TIP: If you need to make these treats a couple of days ahead of time (no more than 2 days ahead of time), then I suggest increasing the butter in the base recipe below from 6 Tablespoons to 8 tablespoons. This will keep your treats nice and soft in the days to come. Then, slice the Lucky Charms Treats as normal, and make sure you place them in an airtight container until you’re ready to serve them!

Cook’s Note – Lucky Charms Treats:

• This recipe makes a TON–24 hefty-sized treats. You can easily halve the recipe.
• These Lucky Charms Treats would also be great for potlucks and bake sales because they make a TON!
• These will keep in an airtight container at room temperature for about 3 days. After 3 days they start getting a little stale and hard.
• I garnished this recipe with 1/2 cup of the marshmallows from Lucky Charms cereal, you can either pick through the box to get 1/2 cup OR buy the marshmallows on Amazon!

US Customary - Metric

Instructions

• Line a 13x9-inch baking pan with foil, extending foil over edges. Lightly spray foil with nonstick cooking spray.
• In a very large pot or Dutch oven melt butter over low heat. Add marshmallows; stir constantly and cook until melted. Remove pot from heat and stir in marshmallow fluff and vanilla. Gently stir in Lucky Charms and jimmies until cereal is evenly coated. Pour mixture into prepared pan and use wax paper over the top to press mixture firmly into the pan without it sticking to your hands. Let treats cool for at least 1 hour before frosting.
  

FOR THE BUTTERCREAM:

• Using a stand mixer beat butter on medium-high speed until smooth, about 30-60 seconds. Reduce speed to medium-low and slowly add confectioners’ sugar, and beat until smooth, about 2-5 minutes. Add vanilla, cream, and salt and increase speed to medium-high and beat until light and fluffy, about 4-8 minutes. Spread buttercream evenly over treats (I like using a small offset spatula).
  

TO FINISH:

• Top with Lucky Charms marshmallows and rainbow jimmies. Using the foil liner, lift treats from pan. Cut into 24 bars and serve.
