St. Patrick’s Day Popcorn
My most popular St. Patrick’s Day recipe is Leprechaun Bait, and with the holiday just around the corner, I knew I wanted to test another variation—a popcorn snack mix version. Let me tell you, it did not disappoint!
My kids are popcorn fanatics, but when you add creamy white chocolate, colorful M&M®’s, and Lucky Charms® marshmallows, they’re completely hooked.
The combination of salty popcorn and sweet, indulgent toppings makes this snack mix absolutely irresistible.
How To Make St. Patrick’s Day Popcorn:
- Use fresh popcorn: Fresh popcorn tastes the best and stays crispy; remove any unpopped kernels.
- Melt white chocolate: Microwave in 30-second steps, stirring often so it doesn’t burn.
- Use a large bowl: Mix popcorn and chocolate in a large bowl to mix without making a mess.
- Add mix-ins quickly: Stir in M&M’s, marshmallows, and sprinkles right after the chocolate, so everything gets coated.
- Let chocolate harden: Spread the mix on parchment or a baking mat to harden, or refrigerate to speed it up.
Quick Tip
To get rid of unpopped kernels, put the popcorn in a large bowl, cover with a rack, flip, and shake. The unpopped kernels will fall out. Scoop out the rest of the popcorn and continue with the recipe.
St. Patrick’s Day Popcorn Ingredients
- Popcorn: Pre-popped popcorn saves time. If you prefer to pop your own, use these packets, kernels in a popcorn machine, or stovetop.
- White Chocolate: Use melting wafers or white chocolate chips for a better melt and flavor.
- Oil: Add a bit of oil or shortening to the chocolate before melting to smooth it out.
- M&M’s: I use 3-different kinds of M&Ms, you can use one or two types. Or pick greens out of a regular bag.
- Lucky Charms Marshmallows: You can pick these out of the cereal or buy just the marshmallows online.
- Sprinkles: Optional, but green sprinkles add a fun crunch and color!
Storage
St. Patrick’s Day Popcorn Storage
For the best flavor, enjoy this popcorn fresh within 1-2 days.
Store it in a sealed container at room temp.
The white chocolate makes it soggy over time, so it’s best to eat it soon. To keep it crispy longer, put it in the freezer.

St. Patrick’s Day Popcorn
Ingredients
- 10 cups popped popcorn unbuttered (Note 1)
- 2 cups white chocolate chips (or white chocolate melts)
- 1½ teaspoons vegetable (or canola) oil
- ½ cup regular M&M's (pull out the greens) (Note 2)
- ½ cup pretzel or crunchy cookie M&M's (pull out the greens)
- ⅓ cup miniature M&M's (pull out the greens)
- 1 cup Lucky Charms marshmallows (Note 3)
- 1-2 tablespoons green sprinkles, optional
Instructions
- PREP: Line an extra-large sheet pan with foil, parchment paper, or a silicone liner. Set aside. In a very large bowl, measure and add the popped popcorn. Separate out all the green M&M's and marshmallows from the cereal. Measure and set aside.
- WHITE CHOCOLATE: Place the white chocolate chips and oil in a microwave-safe bowl. Microwave in bursts of 30 seconds stirring in between each burst until the chocolate is melted and smooth. Be patient to avoid burning the chocolate. Once the white chocolate is smooth and fully melted, use a spatula to scrape it out and over the popcorn. Working quickly, toss together to coat in the white chocolate.
- FINISH MIX: Immediately add in all the different M&M's and the Lucky Charms marshmallows. Toss again to coat in the chocolate. Dump mixture onto prepared pan, space in one layer, and immediately sprinkle with sprinkles (if using).
- HARDEN: Let the popcorn harden at room temperature or in the fridge until it becomes solid. Once solid, break it into pieces and enjoy! Store any leftovers in an airtight container at room temperature. For the best flavor, eat within 1-2 days.
