Lucky Charms Marshmallow Treats

Happy St. Patrick’s Day everyone!  Let’s celebrate all things, Irish, green and leprechauns with some Lucky Charm Marshmallow Treats.  A family friendly treat that is easy to make and sure to please everyone…because they are magically delicious!  But not just a recipe today!  I have included  a side of Lucky Charm shenanigans too 🙂

I am not of Irish heritage, but I celebrate all holidays because I like to decorate my house, and also because I know you guys want some holiday treats!  So if you are last minute scrambling to make some St. Patrick’s Day desserts, here I am to the rescue!  These marshmallow treats require just a few ingredients, are no bake and don’t take long to cool and set before you can cut into them.

I was racking my brain trying to decide on a St. Patrick’s Day dessert to share with you guys, and was pretty set on making you my Homemade Peppermint Patties (a favorite of Ethan’s, my mom and Leigh).  But well…I got busy.  Time for Plan B.  So there I was babysitting my nieces the other day, and was quite entertained while watching Miss A attempt to get ONLY the marshmallows from her snack catcher cup full of Lucky Charms cereal.  Here’s the cup I am talking about (it prevents Lucky Charms from being thrown all over Auntie KK’s living room floor):

Miss A was almost getting mad at this darn cup, for trying to keep her marshmallows from her!  It was pretty hysterically watching Miss A look at the cup and then jam here little fingers in the cup, trying to fish out just the marshmallows.  But I can’t really blame her….I mean, isn’t that why we eat Lucky Charms??  For the marshmallows?!  No one eats Lucky Charms for the oat cereal in there.  So.  Watching Miss A with her Lucky Charms gave me the idea to use Lucky Charms for a St. Patrick’s Day dessert.  And obviously everything is better with marshmallows.  So that’s how I came up with these treats!

And then that leads me to Lucky Charms shenanigans…

Shenanigans at the firehouse always ensue, but don’t mess with a firefighter and his food.  The guys work 48-hours straight, which equals six meals eaten at the firehouse.  While the guys may all eat a communal dinner together as a firehouse, usually the guys will bring in their own food for breakfast and lunch.  So my husband, ever the joker he thinks he is, conspired with another firefighter, to play a joke on Rod (another firefighter).  Rod loves Lucky Charms and had brought a brand new box in for his breakfast in the morning.  James decided it would be funny to discretely take the unopened box of Lucky Charms, open the box from the bottom and slit the bottom of the cereal bag.  James removed the cereal from the bag and separated out all the marshmallows from the oat cereal.  James put just the oat cereal back in the cereal bag and sealed the bottom of the bag, and the bottom of the box, back up.  So looking at the box of Lucky Charms, it still looked unopened.

And then breakfast rolls around and Rod goes to open his box of Lucky Charms.  Totally confused by what he thought was his unopened box of Lucky Charms, which had no marshmallows in it!  What the what?!  Hahahaha.  James saved all the marshmallows they had taken out of the box of Lucky Charms and gave them back to Rod, after James was done playing his little prank.  Probably a good idea too.  Rod’s a big guy…I wouldn’t mess with him!

Ok.  Finally.  The recipe.  Every bite of these Lucky Charms Marshmallow Treats are yummy.  Whether you get pieces of oat cereal or marshmallow.  Because we are coating everything in MARSHMALLOWS!  Yesssssss……no having to pick out the marshmallows with these treats y’all!  These marshmallow treats are ooey-gooey and I used a bit of white chocolate in these too.  Now don’t go all hating on me for the white chocolate.  You can’t taste it, but it adds a unique richness and decadence to these marshmallow treats, which set these apart from any other marshmallow treat you have ever had.  But the white chocolate is totally optional, if you are against it.

Lucky Charms Marshmallow Treats

Print Recipe
Serves: 24 Cooking Time: 0-minutes


  • 1/2 cup unsalted butter
  • 1 (16-ounce) bag mini marshmallows
  • pinch of salt
  • 1 teaspoon VAIN Tahitian Vanilla Extracted in Cane Rum
  • 1/4 cup white chocolate chips or 2-ounces white baking chocolate, broken into pieces (optional but see note below)
  • 1 (11.5 ounce) box of Lucky Charms cereal



Line a 9x13-inch baking pan with foil and spray with baking spray. Set aside.


In a medium sized sauce pot, add the butter, and melt on the stove top over medium-high heat. Once the butter has melted, add the entire bag of marshmallows to the butter. Once marshmallows start to melt, add a pinch of salt to the pot. Continue to stir the mixture continuously until all the marshmallows have melted. Once the marshmallows are completely melted, remove the pot from the stove top. Immediately stir in the vanilla extract to the marshmallow mixture. Add the white chocolate to the marshmallow mixture and stir until chocolate is mostly melted. Add the Lucky Charms cereal one cup at a time to the marshmallow mixture, stirring each cup of cereal in completely before adding the next. Continue adding cereal to the marshmallow mixture, until the entire box of Lucky Charms is mixed in the marshmallow mixture.


Pour mixture into prepared pan and GENTLY press mixture evenly into the pan. Spray one of your hands with baking spray to gently press the mixture into the pan, if the mixture keeps sticking to your hand or fingers. Let treats cool completely before cutting into desired sized squares.


You can't taste the white chocolate in this recipe! The white chocolate just adds a gooeyness and decadence to these treats. Totally optional to add the white chocolate. If you leave the white chocolate out, just make the recipe as directed minus the white chocolate part. Store treats at room temperature in an airtight container. Treats stay fresh for 3-4 days.

Marshmallowy goodness you don’t have to dig through a snack cup to find.  And no chance of the Lucky Charms marshmallows disappearing from these bars either 😉

Oh and I added sprinkles on top of my marshmallow treats.  Because sprinkles are pretty 🙂

Aren’t these fun and colorful??  These treats would be great for any party or get together!

The perfect treat to make for the lucky leprechaun in your life, because they’re magically delicious 🙂 Whip these babies up, share with your favorite people, put your green on and have a Happy St. Patrick’s Day!
