Every bite delivers that irresistible contrast between crunchy popcorn and soft, chewy caramel coating. It comes together with simple pantry ingredients and makes an excellent treat for movie nights, holidays, parties, bake sales, or whenever you’re craving something sweet and homemade.
Ingredients
8 cups popped popcorn – The crisp base that gives this treat its signature crunch. Use plain popcorn without heavy butter or salt for the best flavor.
½ cup butter – Creates a rich, buttery caramel base and helps coat the popcorn evenly.
1 cup brown sugar – Provides the deep, molasses-like sweetness and classic caramel flavor.
2 tablespoons corn syrup – Helps create a smooth, cohesive caramel mixture and contributes to the glossy texture.
10 ounces marshmallows – The secret ingredient that makes this caramel corn wonderfully soft, chewy, and gooey.
1 teaspoon vanilla extract – Enhances the buttery caramel flavor and adds a warm, aromatic finish.
How to Make Marshmallow Caramel Corn
1. Prepare the popcorn
Pop enough popcorn to measure 8 cups. Place it in a very large mixing bowl, removing any unpopped kernels as you go.
2. Make the caramel base
Add the butter and brown sugar to a saucepan over medium heat. Stir constantly until the butter has melted and the brown sugar is thoroughly combined.
3. Add the corn syrup
Pour in the corn syrup and continue stirring until the mixture becomes smooth and well incorporated.
4. Melt in the marshmallows
Cut the marshmallows into smaller pieces if desired. Add them to the saucepan and stir gently until completely melted into the caramel mixture.
The mixture should be smooth, thick, and glossy.
5. Add vanilla
Remove the saucepan from the heat and immediately stir in the vanilla extract.
6. Coat the popcorn
Pour the warm marshmallow caramel mixture over the popcorn. Using a large spatula or wooden spoon, gently toss everything together until the popcorn is evenly coated.
Work fairly quickly because the coating will become thicker as it cools.
7. Let it cool
Spread the coated popcorn over a large parchment-lined baking sheet. Separate large clumps slightly if you prefer smaller pieces.
Allow it to cool for about 10–15 minutes, or until the coating has set enough to handle.
8. Break and serve
Break the cooled caramel corn into bite-sized clusters and serve.
For storage, place it in an airtight container and enjoy within about 5 days.

Pro Tips for the Best Caramel Corn
Use fresh popcorn. Freshly popped popcorn gives you the best texture and prevents the finished treat from becoming stale.
Remove unpopped kernels. Nobody wants to bite into a hard kernel hiding beneath the caramel coating.
Use a large bowl. You’ll have much more room to toss the popcorn without spilling caramel everywhere.
Stir constantly while making the caramel. This helps the butter and sugar combine evenly.
Don’t overcook the marshmallow mixture. Once the marshmallows are melted and incorporated, take the mixture off the heat.
Add vanilla off the heat. This preserves its fragrant flavor.
Coat the popcorn while warm. The caramel mixture spreads much more easily before it begins to cool and thicken.
Line your baking sheet with parchment paper. It makes cleanup dramatically easier and helps prevent the caramel corn from sticking.
Let it cool completely before storing. Trapping warmth in an airtight container can create condensation and make the popcorn less crisp.
Serving Ideas
Serve Marshmallow Caramel Corn by itself as an afternoon snack or movie-night treat. For parties, place it in small paper bags or decorative cups for individual servings.
You can also turn it into a festive dessert by mixing in pretzels, chocolate chips, M&M-style candies, peanuts, or holiday sprinkles after the caramel coating has cooled slightly.
For gifting, package cooled caramel corn in clear treat bags tied with ribbon—it makes an inexpensive homemade gift that looks just as good as it tastes.
