Lucky Charms Snack Mix

When it comes to St. Patrick's Day desserts, this easy cereal mix just might have all others beat simply for its addictive qualities. This leprechaun bait is impossible to resist!

If you need a last minute snack idea that is great for kids' school parties or no bake treats to make on St. Patrick's Day, this is such a fun option. Little leprechaun helpers like my 6 and 4 year old girls enjoy dumping the ingredients into a big bowl and stirring it all together.

And they love sneaking those marshmallows when mom isn't looking, lol.

Last year on St. Patrick's Day, we made a leprechaun trap for the first time since it was our first year with an elementary school aged child. But in the morning, when my then-Kindergartner saw that the trap had been sprung, she panicked and refused to check it.

She was totally convinced that there was a leprechaun trapped inside the box and begged me not to let it out.

It wasn't until after breakfast that she screwed up enough courage to peek.

Unfortunately those sneaky leprechauns had escaped while she hesitated, but at least they left behind some gold coins.

Then the leprechauns struck again at school while her class was out to recess, pulling out pencils, overturning chairs, and sprinkling glitter everywhere in her classroom.

Clara was absolutely livid about the mess those naughty leprechauns made! I was dying over her anger at their bad behavior and she went on and on about how bad leprechauns are. Kids are the best.

By the way, don't wait until next week to make this Lucky Charms snack mix. National Cereal Day is March 7th and it's a great excuse to enjoy this yummy treat!

My kids and husband LOVE Lucky Charms. It's probably their favorite "sugar cereal", which we don't have very often at our house.

Growing up, my dad always teased that they were called "Yucky Charms", and I do the same thing with my girls, who always giggle and groan at me that I'm getting the name wrong, AGAIN, lol.

But while I eschew them for breakfast in favor of something more substantial, I have to confess that I love this sweet, crunchy cereal with those weird little "marshmallows" as a treat. Especially when they are counter balanced with salty pretzels and popcorn and creamy white chocolate.

St. Patrick's Day Desserts

Even if you aren't Irish, you can still celebrate St. Patrick's Day and I've got some great desserts to help you do it! If you want to take a rainbow approach, obviously this snack mix is a great idea. So is my rainbow jello, which is always a hit!

But you could also make my Homemade Rainbow Chip Frosting and use it to frost chocolate cupcakes. Or play up the green color scheme with these fudgy frosted chocolate mint brownies, which are great for sharing with friends or co-workers.

You could even amp up the green in this cereal snack mix by sorting out just the green and yellow M&M's from a party size bag and only using those instead of the pastel M&M's that I chose to use in the pictures here.

Throw in some holiday appropriate green shamrock and white and gold sprinkles (or Easter sprinkles - this snack mix is so easy to adapt to other holidays) and pastel M&M's and you've got an irresistible combination of flavor and texture that is almost impossible to stop reaching for.

How to Melt White Chocolate

  • Bars of actual white chocolate that are chopped into small, uniform pieces will melt better than using white chocolate chips, which contain stabilizers that are actually intended to help the chips hold their shape and not melt.
  • Go slow! White chocolate seizes and burns more easily than dark or milk chocolate, so a lower heat and slow melting is better.
  • Be sure to stir frequently and thoroughly, even if the white chocolate doesn't seem to be melting. This will help keep the white chocolate from getting too hot, as well as assist with even melting.
  • Keep the white chocolate totally dry. Make sure any cutting boards, knives, bowls, spatulas for stirring, etc. used to melt the white chocolate are completely dry before using them with the white chocolate. Water can make the white chocolate seize up.

My preferred approach is to melt the white chocolate in a glass bowl set over a pan of simmering water, making sure the water doesn't touch the bottom of the bowl. It's a make-do double boiler and I feel like it gives me the greatest control and ability to see how close the white chocolate is getting to being completely melted.

Just stir the chopped white chocolate frequently and remove it from the pan of hot water before the white chocolate is completely melted! The residual heat from the white chocolate that has already melted and the bowl itself should be enough to finish melting the rest of the white chocolate, and if not, you can always stick the bowl back over the water for a little bit to help warm the chocolate back up and finish melting.

But you can also take the approach where you melt white chocolate in the microwave. Many microwaves have functions for melting chocolate where it automatically decreases the power of the microwave, or you can just melt at 30% to 50% power in 20-30 second intervals, stirring well between each interval and maybe even doing shorter intervals towards the end.

Again, you will want to stop before the white chocolate is completely melted and let the residual heat in the bowl and melted white chocolate do the work of finishing the job.

How to Make Leprechaun Bait

This recipe is a cinch to throw together.

  1. Combine the Lucky Charms cereal, pretzels, popcorn, M&M's, sprinkles, and peanuts (if using) in a big bowl
  2. Melt the white chocolate
  3. Pour the melted white chocolate over the cereal mixture and toss well to coat everything.
  4. Spread the cereal mix onto a baking sheet lined with parchment paper and let it set for 10 to 15 minutes until the white chocolate hardens.

This recipe makes a big batch, and I'll admit it's dangerous to have around, but on the plus side, it doesn't last long. As a variation, you could swap out the popcorn for Chex cereal and add 1 ½ cups of dry roasted peanuts to the mix.

This magically delicious Lucky Charms Snack Mix has a rainbow of Spring colors and is a fun, sweet treat for snacking!  Made with pretzels, M&M's, white chocolate, popcorn, sprinkles, and of course, Lucky charms, this is a hard-to-resist goodie that is fun for both St. Patrick's Day and Easter.


  • 5 cups Lucky Charms cereal
  • 3 cups pretzels
  • 6 ½ cups popped popcorn
  • 10 ounces M&M's
  • ¾ cup sprinkles of your choice
  • 1 ½ cups dry roasted peanuts optional
  • 4 cups good quality white chocolate, chopped or white candy melts 24 ounces


  • Line a large baking sheet with parchment paper.
  • In a large bowl, combine the cereal, pretzels, popped popcorn, M&M's, sprinkles, and peanuts, if using.  
  • In a separate bowl, carefully melt the white chocolate in short 20-30 second bursts in the microwave and stirring well between each burst of heat until the white chocolate is smooth.  
  • Pour the melted chocolate over the other ingredients and mix well to coat all of the snack mix in white chocolate.    Transfer the mixture to the parchment lined baking sheet and spread out.
  • As the white chocolate cools, the snack mix will firm up and set (about 10 to 15 minutes).  When set, break into pieces and store in an airtight container.  


* I prefer the regular buttered kind but you could use kettle corn or another variety if you like.
If you opt to use white chocolate chips, add 3 tablespoons of oil to them before melting.  It will help them melt better and more smoothly since they have ingredients added to help them keep their shape and not melt as easily.

    Oh my goodness, I love Lucky Charms, even as an adult I always buy a box every time I go shopping. Thanks for sharing I will be making this soon.

    This is such a colourful mix of just about everything that I love! I get excited just by looking at it! What a fantastic idea for St. Patrick's Day!

    Haha, your daughter sounds so funny! I am fairly certain I would react the same way when I was in kindergarten too :p
    This looks amazing! I remember NEVER getting lucky charms as a kid, unless I went to a friend's house. All I had in my house was bran flakes and puffed wheat 🙁 This looks like such a great treat

    Lucky Charms was one of my favorite cereals as a kid. I love the little sweet marshmallows also.... This Lucky Charms Mix looks sooooo good! I like the addition of the salty pretzels to balance the sweet. YUM!

  7. 5 stars
    So fun! I loved your story! I'm like you...I dont want sugary cereal in my house either but I have to say this does look delish and my kids would love to make this! It's always fun to make memories on fun holidays!

    Cute story about the leprechaun trap. I'd never heard of the custom -- St. Nicholas Day yes, but this Irish fun custom is adorable. And the treats sound delicious!! I love the idea of the snacks versus lots and lots of sugar. This extends the sugary treats somewhat. I hate to admit this but I've never eaten Lucky Charms -- perhaps I should change that.

    LOL _ My mom always insisted we couldn't have the sugar cereals as cereal for breakfast - but we could have them as candy for snacks. But we dodn't think much of them as candy... This mix might have changed our minds (while adding nuts and pretzels would have relived hers!)

  10. This is SUCH a fun treat! My 6-year-old would go nuts for it! I used to loooove Lucky Charms (which I'm always going to think of as "Yucky Charms" now, thanks to your dad - ha!!). My SIL recently introduced me to "marbits" - they're bags of JUST the marshmallow bits that taste just like the ones from Lucky Charms, but without the cereal component. You can buy big ol' bags of them at some of the Amish shops out in Indiana.

    Oh my Gosh!!!!! I love this. When I was a kid we were only allowed to have one sugary cereal a year on our birthday and mine was always luck charms, so this is already a favourite snack of mine!

    Lucky Charms were my JAM as a kid. I can't remember the last time I had a bowl... but I need this snack mix in my life. I know a couple of kids who would go crazy about this!
