Why You Will Love This Festive Popcorn Mix
There are a million Christmas cookie recipes out there, but sometimes you need a break from the oven. Here is why this popcorn mix deserves a spot in your holiday rotation:
- Visual Impact: The bright green color against the red M&Ms creates a stunning, festive look that pops on any dessert table.
- Sweet & Salty Balance: The combination of salted butter, plain popcorn, and sweet marshmallow glaze strikes that addictive cravings balance.
- Kid-Friendly: This is a fantastic recipe for little helpers. They can help mix in the marshmallows and candies (and sneak a few bites along the way).
- Customizable: While we love the classic M&M and marshmallow combo, you can easily swap in other festive treats.

Ingredients Needed
To make this gooey green masterpiece, you will need just a few simple ingredients. The magic here is in the technique of melting the coating to ensure every kernel gets that signature “Grinch” green glow.
- Popped Popcorn – You will need about 10-12 cups. You can use microwave popcorn (choose a plain or lightly salted variety, avoid heavy yellow butter flavors as they mess with the green color) or air-popped corn.
- Butter – Unsalted sweet cream butter works best to control the saltiness, but salted works if you love that savory contrast.
- Mini Marshmallows – You will need a bag for melting down into the sauce, plus extra handfuls to toss in whole at the end.
- Green Food Coloring – Gel food coloring is superior here as it provides a vibrant neon color without watering down your marshmallow mixture.
- Vanilla Extract – A splash brings a bakery-style flavor to the simple sugar glaze.
- Red M&Ms – To represent the Grinch’s heart! You can pick out the red ones from a holiday bag.
- Extra Mini Marshmallows – For texture variety in the final bowl.
Step-by-Step Instructions
Follow these simple steps to create the perfect batch of Grinch Popcorn. Work relatively quickly once the marshmallow mixture is melted, as it gets stickier as it cools!
1. Prepare the Popcorn
Pop your popcorn according to package directions or use an air popper. Make sure to sift through the popcorn and remove any unpopped kernels (also known as “old maids”)—nobody wants to bite into a rock-hard kernel! Place the popped corn in a very large mixing bowl.
2. Melt the Marshmallow Mixture
In a medium saucepan over medium-low heat, melt the butter completely. Once melted, add the bag of mini marshmallows. Stir constantly with a silicone spatula until the marshmallows are completely melted and the mixture is smooth. Remove from heat immediately.
3. Add Color and Flavor
Stir in the vanilla extract and several drops of green food coloring. Start with a few drops and add more until you reach a vibrant, slime-green color. Remember, the color will look slightly lighter once spread over the white popcorn, so go a shade darker than you think you need.
4. Coat the Popcorn
Pour the green marshmallow mixture over the popcorn in the large bowl. Using a greased spatula (spray it with a little non-stick spray first!), gently fold the mixture into the popcorn. Toss until the kernels are evenly coated in green.
5. Add Mix-ins and Cool
Spread the sticky green popcorn out onto a baking sheet lined with parchment paper. While it is still tacky, sprinkle the Red M&Ms and the extra fresh mini marshmallows over the top. Press them down slightly so they stick to the popcorn. Let it cool and set for about 10 minutes.
6. Serve
Break the popcorn into chunks and serve in a large bowl. Enjoy your movie night!
Tips for the Perfect Green Popcorn
Avoid Burnt Popcorn: If using microwave bags, listen carefully. Burnt popcorn has a strong flavor that even marshmallows can’t hide.
The “Sticky” Factor: This is a marshmallow-based treat, so it will be sticky like a popcorn ball! If you prefer a dry, candy-shell crunch, you would need to boil sugar and corn syrup to the hard-crack stage, but the marshmallow version is softer and more kid-friendly.
Work Fast: Marshmallow cools quickly. Have your M&Ms and extra marshmallows ready in a bowl before you start melting the butter.
Gel vs. Liquid Dye: We highly recommend gel food coloring. Liquid drops can seize up chocolate (if you use white chocolate instead of marshmallow) and often result in a pastel mint green rather than a deep Grinch green.
Variations to Try
Want to switch things up? Here are a few ways to customize your batch:
- The “White Chocolate” Method: Instead of marshmallows and butter, melt white chocolate chips or green candy melts. This results in a crunchier, less sticky coating.
- Minty Twist: Add a drop of peppermint extract along with the vanilla for a cool, wintry flavor profile.
- Extra Hearts: Use large red heart sprinkles instead of M&Ms to really emphasize the “heart grew three sizes” theme.
- Pretzel Crunch: Add pretzels to the bowl before pouring the green mixture for an extra salty crunch.
Serving Suggestions
This popcorn looks amazing served in a large black cauldron-style bowl or clear glass jars to show off the colors. For parties, you can scoop portions into clear cellophane bags and tie them with red ribbon for an adorable edible party favor. It also makes a great addition to a “Christmas Charcuterie Board” alongside gingerbread men and candy canes.

Frequently Asked Questions
How long does this keep?
It is best eaten the same day, as the popcorn can soften over time due to the moisture in the marshmallows. However, stored in an airtight container, it will stay tasty for up to 2 days.
Can I freeze it?
We do not recommend freezing this popcorn. The texture of the popcorn will become chewy and the marshmallows may get soggy upon thawing.
Why is my popcorn soggy?
This usually happens if the butter/marshmallow ratio is off, or if it’s stored in a humid environment. Ensure you let it cool completely on the baking sheet before putting it in a container.
