How to Make Marshmallow Caramel Corn
Step 1: Prepare the Popcorn
Start by popping your popcorn using whichever method you prefer — whether it’s an air popper, stovetop, or even microwave bags. The goal is to get light, fluffy, and crisp popcorn that will gladly soak up the caramel-marshmallow coating. Make sure to remove any un-popped kernels to avoid any unpleasant surprises as you enjoy your snack.
Step 2: Make the Caramel
In a medium saucepan, melt the unsalted butter over medium heat. Once melted, stir in the packed brown sugar and corn syrup, bringing the mixture to a gentle simmer. Keep stirring constantly for about 5 minutes until the caramel sauce becomes thick and smooth. This step is essential to getting that perfect caramel flavor and smooth texture that will cling to the popcorn.
Step 3: Add the Marshmallows
Lower the heat slightly, then add the large marshmallows to the saucepan. Stir continuously until the marshmallows fully melt and blend seamlessly with the caramel sauce, creating a luscious, sticky coating. This is what sets Marshmallow Caramel Corn apart — the combination of ooey-gooey marshmallow with buttery caramel is pure magic.
Step 4: Coat the Popcorn
Pour the warm caramel-marshmallow mixture over your freshly popped popcorn. Gently toss everything together using a spatula or wooden spoon, ensuring every popcorn kernel gets an even, sweet coating. Be careful not to crush the popcorn as you mix to maintain that satisfying crunch in every bite.
Step 5: Bake for Crunch
Spread the coated popcorn out evenly on a baking sheet lined with parchment paper. Pop it into your oven preheated to 250°F (120°C) and bake for 30 minutes. To ensure every piece has that perfect, crunchy coating, stir the popcorn every 10 minutes. This step bakes the coating onto the popcorn, enhancing the texture and ensuring the Marshmallow Caramel Corn holds together beautifully.
Step 6: Cool and Serve
Once baked, allow the popcorn to cool completely on the baking sheet. This cooling step allows the coating to crisp up to perfection. After it cools, break the popcorn into clusters or smaller pieces and get ready to enjoy your homemade Marshmallow Caramel Corn. It’s addictive, so you might want to double the batch!
How to Serve Marshmallow Caramel Corn

Garnishes
If you want to add a little extra flair while keeping it simple, sprinkle chopped toasted nuts like pecans or almonds on top before baking. A light dusting of sea salt after baking also creates a wonderful sweet-and-salty contrast that elevates the flavor profile nicely.
Side Dishes
Marshmallow Caramel Corn pairs wonderfully with a chilled glass of milk or hot drinks like coffee or cocoa. It’s an excellent sweet counterpoint for richer desserts, and it works just as well alongside a scoop of vanilla ice cream for an indulgent treat.
Creative Ways to Present
Serve your Marshmallow Caramel Corn in festive bowls, gift bags, or even inside small mason jars tied with a ribbon for parties or holiday gifts. You can also layer it in parfait cups with yogurt and fruit for a playful dessert twist that’s sure to impress.
Make Ahead and Storage
Storing Leftovers
Store any leftover Marshmallow Caramel Corn in an airtight container at room temperature. It should stay fresh and crunchy for up to a week. Avoid humid areas as moisture can soften the crunchiness.
Freezing
If you want to keep your treat longer, freezing is possible. Place the popcorn in a sealed freezer-safe bag or container and freeze for up to 2 months. To thaw, simply leave it out at room temperature for a few hours, and it will regain much of its delightful texture.
Reheating
To refresh the crunch of any stored Marshmallow Caramel Corn, pop it in a preheated oven at 250°F (120°C) for about 5-10 minutes. Keep an eye on it so it doesn’t burn, and stir halfway through reheating to warm it evenly.
FAQs
Can I use regular marshmallows instead of large ones?
Yes, you can substitute regular-sized marshmallows; just be sure to adjust the quantity slightly so the texture remains gooey enough to coat the popcorn perfectly.
Is it better to use salted or unsalted butter?
Unsalted butter is best because it allows you to control the saltiness in your Marshmallow Caramel Corn. You can always add a pinch of salt later if you like.
Can I make this recipe vegan?
To make a vegan version, use a plant-based butter alternative and check that your marshmallows are vegan-friendly (some brands do offer vegan marshmallows).
How long does Marshmallow Caramel Corn stay fresh?
When stored properly in an airtight container at room temperature, it stays fresh for up to one week without losing its crispness.
Can I add other mix-ins to this recipe?
Absolutely! Try tossing in nuts, pretzels, or even mini chocolate chips once the popcorn has cooled slightly for delightful texture and flavor surprises.
