Marshmallow Caramel Popcorn
If you’re a fan of my microwave caramel corn and caramel candy, you’re going to love this gooey marshmallow popcorn version even more. I normally just add popcorn seasoning to my favorite salty popcorn, but my grandma gave me this recipe and after one bite, I was hooked.
The marshmallow mixture almost reminds me of Rice Krispie treats, but the brown sugar takes it over the top. It’s seriously so addicting!
This marshmallow caramel corn makes an easy no-bake dessert to whip up in a pinch and is a great recipe to make with your little ones. Try it with homemade marshmallow fluff for something even more decadent!
It’s so easy throw together and requires only 4 ingredients. In just 15 minutes from start to finish, you’ll have an amazing dessert that your family can’t get enough of!

Tips + Variations
- Popcorn: To make it easier, I bought a bag of pre-popped popcorn (Skinny Pop is my favorite). You can also make your own stovetop popcorn or cook microwave popcorn if preferred.
- Extras: Once you spread the marshmallow popcorn out on a piece of wax paper, feel free to sprinkle any favorite candies on top. We like to add mini M&M’s, mini chocolate chips or some colorful sprinkles. You can even turn this into s’mores popcorn by adding Golden Grahams and chocolate chips!
- Gifting: This popcorn would be fun served in little cups or packaged up in clear bags. They would make great party favors, neighbor gifts or just a fun mini dessert to serve at your next dinner party.
Storing Marshmallow Popcorn
This is one of those recipes that tastes best served the first day so that the marshmallow caramel mixture on the popcorn doesn’t get stale or lose it’s flavor and texture. Leftovers will keep in an airtight container or bag for about 2 days, although I recommend enjoying it the day it’s made if possible!

How do I get the popcorn to not soften? I love the flavor, but the popcorn got super soft.

Hi Lila, this marshmallow popcorn is best served right away, it does get soft in storage.
