You can’t beat a sweet-salty snack mix, right?

This one is all kinds of perfect and easy to make for St. Patrick’s Day festivities, whether you’re hosting a party, celebrating with your little family or just want something colorful for March 17th.

We’re working our way through the holidays with these Sweet Chex Mix recipes (see Chex Mix Puppy Chow, Bunny Bait Easter Snack Mix, Christmas Chex Mix and Valentine’s Day White Chocolate Chex Mix).

This St. Patrick’s Day recipe is a fun twist on the classic.

Why I love this recipe:

This snack mix recipe is perfect for crunching, and it has a white chocolate base. (Unlike puppy chow, we don’t involve peanut butter or milk, bittersweet or dark chocolate.)

This Chex mix recipe starts with the classic sweet Chex mix base—your favorite Chex cereal.

But then we add in Lucky Charms—both the cereal plus extra marshmallows for color and flavor—to give it a distinctly St. Patrick’s Day feel.

Green M&M’s (sort those out of the bag or purchase a bag of the green ones only) and St. Patrick’s Day sprinkles complete the effect.

One thing I love about this snack mix recipe is that it’s easy to customize to your tastebuds, too, so more on that below.

In addition to those tools, you’re also going to need some ingredients. Be sure to scroll all the way down to the recipe card to get the exact amounts.

  • Chex Cereal—you can use rice, corn or any combination of the two. I used the Rice Chex in these photos.
  • Lucky Charms—we need the cereal and some extra marshmallows. The regular-sized box should be completely fine to do both, but you will have to sort out the marshmallows for the extra marshmallows in this recipe. It’s worth the hassle.
  • Mini pretzel twists—you could also use small pretzel rods if you like those better, but I personally like the shape of these!
  • Lightly salted roasted peanuts—these add such a nice salty crunch!
  • Green M&M’s (or other colorful chocolate-coated candies)—while you could use all the M&M colors, the green ones are extra perfect for this snack mix. You can sort them out (which is what we did) or purchase a pre-made St. Patrick’s Day mix, like this one.
  • White chocolate melting chips—I like these better than white chocolate chips because they melt more easily. These Ghirardelli White Melting Wafers are my favorite.
  • St. Patrick’s Day sprinkles—these add some pops of color and crunch to the snack mixture!

Substitutions for this St. Patrick’s Day snack mix recipe:

Because you can definitely make ‘em, here are a few thoughts on what swaps would still yield an awesome result.

  • Chex Mix: You can use a combination of Rice Chex and Corn Chex or all one variety.
  • Pretzels: You may use pretzel twists, as shown here, or rods!
  • Sprinkles: Use your favorite! While this is a St. Patrick’s Day-themed Chex Mix recipe, you can change up the colors of the sprinkles and candies and make it for any holiday… or just because!

How to make St. Patrick’s Day Chex Mix

Gather your products and tools. This means finding an extra large mixing bowl, as well as getting out the boxes and bags of ingredients.

Also, you need to sort out the extra Lucky Charms marshmallows and green M&Ms at this point. This is a great task for little helpers, if you have them around.

Mix the ingredients together. Do this in an extra large bowl because there is a lot of Chex cereal, Lucky Charms, pretzels, marshmallows and roasted peanuts to stir together.

Pour onto a rimmed baking sheet. Sprinkle on the M&Ms on top.

Melt the white chocolate chips in a microwave-safe bowl. Heat on high power for 60 seconds. Give them a stir to help them finish melting and smooth out the chocolate.

Pro tip: White chocolate burns easily, so keep an eye on it. If any large chunks of white chocolate are remaining after the initial 60 seconds and stirring, melt for 15 seconds more and stir until smooth.

Drizzle on the white chocolate to the cereal mixture.

Sprinkle the holiday sprinkles onto the white chocolate. This will ensure they don’t fall off!

Stir to combine. Use a spoon, rubber spatula or clean hands to mix and toss the mixture to evenly distribute the white chocolate. Work quickly so that you can coat everything before the chocolate sets. Keep in mind that the white chocolate will be hot, so if you’re using your hands, proceed with caution.

Let sit. This snack mix needs to hang out for at least 15 minutes so the chocolate can set and cool completely.

Break it up. If there are any large chunks, break them apart using your hands.

Serve and enjoy!

Erin’s Easy Entertaining Tips

This St. Patrick’s Day White Chocolate Chex Mix recipe would be an excellent snack item to serve at any gathering, whether you’re attending a parade with friends and need a portable snack, are hosting a school party or even just hosting friends to mark the day.

You don’t need an occasion to make this goodness, though.

Here are some things you can do if you want to serve these to a crowd:

  • Make the snack mix in advance. The beauty in this is it can be stored for up to four days at room temperature, so you can make it in advance, then set it out for guests without needing to sweat.
  • Serve it in a big bowl… or pack it up individually! You could put a serving in a small bakery box or individual to-go baggies.
  • Involve your kids. Kids can easily sort marshmallows, as well as separate out the green M&Ms. Measuring, mixing, combining, decorating and serving are all fun activities, too. Prepare to get a little messy!
