This Grinch Popcorn started as a simple treat for our family's Christmas movie gathering but quickly turned into our most cherished holiday custom. The little ones beam with excitement when they spot the vibrant green kernels dotted with those cute red M&M hearts. Nowadays, whenever I prepare it, I can't stop grinning as I think back on all the wonderful moments we've shared around this festive snack.
Beloved Holiday Treat
The magic of this popcorn lies in how it embodies the fun spirit of Christmas time. That irresistible mix of salty and sweet with the sticky marshmallow layer gets everyone coming back for more. And it's so quick to make that I can throw a batch together anytime we're craving a holiday munchie.
Ingredients List
- Popcorn: 8 cups already popped with a touch of salt for that sweet-salty magic.
- Butter: 3 tablespoons to add smoothness and help everything stick together.
- Mini Marshmallows: 4 cups melted down for coating plus extra scattered on top.
- Food Coloring: Yellow and blue drops combined to create that signature Grinch shade.
- Red M&Ms: ½ cup to add festive color pops throughout.
Creating The Wonder
- Begin With Hot Popcorn
- Get your popcorn ready and add just a bit of salt to bring out that amazing flavor contrast.
- Mix Your Grinch Color
- Slowly melt the butter with marshmallows then stir in coloring. The secret is adding the yellow drops first followed by blue until you reach that perfect Grinchy tone.
- Combine Everything
- Drizzle your green marshmallow mix over the popcorn and fold it all together until every kernel gets covered.
- Sprinkle The Extras
- Toss in those bonus marshmallows and red candies while everything's still sticky so they'll cling better.
- Cool It Down
- Wait a few moments for it to harden slightly before digging in.
Custom Variations
I'll throw in smashed candy canes for extra Christmas cheer sometimes or dribble melted white chocolate across the top. My kids go crazy when I add holiday sprinkles to the mix. The adults tend to like when I toss in some salty peanuts or crunchy pretzel pieces.

Storage Tips
Your batch will stay crunchy for several days when kept in a sealed container though it usually disappears much faster in our home. If it starts getting a little soft just warm it briefly in the oven and it'll crisp right up. It makes an adorable Christmas gift when packed in transparent bags tied with colorful ribbons.
Festive Memories
Each handful of Grinch Popcorn brings loads of happiness to our Christmas gatherings. It's become such an important part of our family customs and watching everyone's delight when that bright green snack appears always makes me feel so warm inside.
