Ingredients You’ll Need
Getting started with Marshmallow Caramel Corn is delightfully simple, and the ingredients you’ll use each play a crucial role in creating that perfect flavor and texture harmony. Each component adds depth and richness, whether that’s the buttery smoothness, sweet caramel shine, or the classic marshmallow fluffiness that brings it all together.
- 12 cups popped popcorn: The base of your treat, providing the crunch crowd will love — use about 1/2 cup unpopped kernels for the perfect amount.
- 1/2 cup unsalted butter: Gives your caramel a rich, creamy foundation and keeps everything smooth.
- 1 cup packed brown sugar: Offers that deep, molasses-filled sweetness essential for classic caramel flavor.
- 2 tablespoons light corn syrup: Prevents the sugar from crystallizing while adding that glossy finish to your caramel coating.
- 1 package (10 oz) large marshmallows: About 35 marshmallows melt down to create the irresistibly gooey, soft caramel texture that makes this snack stand out.
- 1 teaspoon vanilla extract: A touch of warmth and complexity that enhances every bite with subtle flavor.
How to Make Marshmallow Caramel Corn
Step 1: Prepare the Popcorn
The first step is all about the popcorn base, so make sure to pop your kernels using whichever method you prefer — an air popper keeps things light, the stovetop can add a little extra flavor, and the microwave is great for convenience. Once popped, spread it out gently in a large bowl, ready to be transformed by the caramel marshmallow sauce. Freshly popped popcorn is your blank canvas for the magic ahead.
Step 2: Make the Caramel
Next, melt the butter in a medium saucepan over medium heat. Stir in the brown sugar and corn syrup, and bring the mixture to a gentle simmer. Keep stirring constantly for about 5 minutes — this step is crucial as it melts the sugar just right and develops that intense caramel flavor that’s both sweet and slightly smoky. This rich caramel forms the delicious base that will coat every kernel.
Step 3: Add Marshmallows
Now comes the fun gooey part — add the entire package of large marshmallows to your warm caramel and stir until they melt completely into a thick, smooth sauce. The marshmallow adds a luscious creaminess that sets this recipe apart from traditional caramel corn. This silky texture is what makes your Marshmallow Caramel Corn delightfully soft and chewy while still maintaining a perfect crunch.
Step 4: Coat the Popcorn
Pour your luscious caramel-marshmallow sauce over the freshly popped popcorn. Gently toss and fold the mixture together using a spatula or wooden spoon, making sure every piece gets a luscious coating. Taking the time to coat the popcorn evenly guarantees bursts of flavor in every bite, allowing that sweet, sticky goodness to cling perfectly to each kernel without overwhelming it.
Step 5: Bake for Crunch
To give your Marshmallow Caramel Corn that satisfying crunchy texture, spread the coated popcorn out evenly on a baking sheet lined with parchment paper. Bake it at a low temperature of 250°F (120°C) for 30 minutes, stirring every 10 minutes to ensure the heat distributes evenly and the coating solidifies without burning. This slow bake is what transforms the gooey coating into a perfectly crisp, addictively munchable snack.
Step 6: Cool and Serve
Once baked, allow the Marshmallow Caramel Corn to cool completely on the baking sheet. This cooling step helps the coating harden and ensures the popcorn breaks apart easily into bite-sized chunks. After cooling, break it into pieces and serve immediately or store it for later enjoyment. The aroma and texture make it impossible to wait too long to dig in!
How to Serve Marshmallow Caramel Corn

Garnishes
Want to elevate your Marshmallow Caramel Corn? Sprinkle a little sea salt before baking to add a sophisticated salt-sweet flavor contrast. You can also toss in mini chocolate chips or colorful sprinkles after baking for a fun twist or an extra pop of texture that makes this snack even more festive and inviting.
Side Dishes
Marshmallow Caramel Corn pairs wonderfully with fresh fruit platters, especially berries or apple slices, which provide a juicy balance to the sweetness. It’s also a delightful companion to warm beverages like hot chocolate or spiced tea, making it a perfect choice for cozy gatherings or holiday parties.
Creative Ways to Present
For parties or gifting, package your Marshmallow Caramel Corn in clear cellophane bags tied with colorful ribbons or place it in festive tins. Layer it in mason jars with other snacks like nuts or pretzels, creating a snack mix that looks as good as it tastes. These thoughtful presentations make the treat feel even more special.
Make Ahead and Storage
Storing Leftovers
If you have any Marshmallow Caramel Corn left (although it’s hard not to eat it all at once), store it in an airtight container at room temperature. It stays fresh and crunchy for up to a week, so you can enjoy these sweet bites anytime without losing any of that irresistible texture.
Freezing
Freezing Marshmallow Caramel Corn isn’t usually necessary, but if you want to keep it longer, you can freeze it in a tightly sealed freezer bag. When properly wrapped, it will retain quality for up to a month. Just be sure to thaw it fully at room temperature before eating to bring back that perfect crunch.
Reheating
If your popcorn softens a bit after storage, a brief reheating in a 250°F oven for 5-10 minutes will help revive the crisp factor. Spread it on a baking sheet to warm evenly and cool completely before munching for fresh-baked crunch every time.
FAQs
Can I use mini marshmallows instead of large ones?
Absolutely! Mini marshmallows will melt just as well, but you may want to check the volume since they pack differently. The end result will still be delicious, just keep an eye on melting time to avoid burning.
Is it possible to make this recipe gluten-free?
Yes, plain popcorn and these ingredients are naturally gluten-free, but always check packaging labels, especially for corn syrup and marshmallows, to ensure they don’t contain any gluten additives.
Can I substitute the corn syrup with honey or maple syrup?
You can try, but corn syrup gives the smooth, non-crystalline texture essential for caramel. Honey or maple syrup may cause the caramel to crystallize or become gritty, so it’s best to stick with corn syrup for the perfect Marshmallow Caramel Corn.
How do I avoid burning the caramel?
Keep the heat medium and stir constantly when simmering your caramel mixture. This steady attention prevents the sugar from sticking to the pan and burning while developing that deliciously rich flavor.
Can I add nuts or other mix-ins?
Definitely! Chopped pecans, almonds, or even peanuts make a great crunchy addition. Add them during the coating or toss them in just before baking to incorporate depth and variety in texture and taste.
