Marshmallow caramel popcorn is the kind of snack that never sticks around long in my house. It is crunchy but sticky in the best way and just the thing to whip up for a party or movie night when you want something sweeter than regular popcorn.
I remember making this for a holiday party one snowy afternoon and my friends still ask for it every time we get together now
Ingredients
- Popped popcorn: Gives the base crunch and volume so choose freshly made popcorn and sift out any unpopped kernels
- Unsalted butter: Adds rich flavor and keeps the coating smooth always pick real butter for best results
- Brown sugar: Gives the caramel flavor and extra chew look for a soft and moist texture in your sugar
- Light corn syrup: Keeps the caramel glossy and helps everything stick together opt for fresh syrup with no crystals
- Large marshmallows: Melt into a gooey binder classic size works best just count out about thirty five or use a kitchen scale
- Vanilla extract: Brings warmth and aroma use pure vanilla for full rich taste and aroma
Step-by-Step Instructions
- Pop the Popcorn:
- Pop your corn using an air popper or stovetop method for the best flavor and largest kernels Remove any unpopped pieces so you don’t bite into any unexpected crunch
- Melt the Butter and Start the Caramel:
- In a large heavy-bottomed saucepan melt your butter slowly over medium heat until fully liquid and fragrant Watch closely so it doesn’t brown or burn
- Add Brown Sugar and Corn Syrup:
- Pour in the brown sugar and drizzle in the corn syrup Stir thoroughly with a wooden spoon until the sugar dissolves into the butter The mixture should look homogenous and glossy
- Melt the Marshmallows:
- Lower the heat to medium low Add all the marshmallows at once Stir constantly as they begin to lose shape and melt into the sugar butter base Continue until the mixture is totally smooth with no marshmallow lumps
- Finish the Caramel:
- Move the pot off the heat and add in the vanilla extract Stir it in well to distribute that aromatic sweetness throughout the mixture
- Coat the Popcorn:
- Pour the hot caramel marshmallow mixture over your bowl of popped popcorn Use a silicone spatula or wooden spoon to gently toss and fold the corn so every piece is coated Take your time to avoid crushing the popcorn
- Set the Popcorn Clusters:
- Spread the coated popcorn out on a large baking sheet lined with foil and misted with nonstick spray Let it cool for about ten to fifteen minutes so the coating sets and the clusters firm up
- Serve and Store:
- Once cool break into large clusters and serve immediately or pack into airtight containers to keep fresh for up to three days

My favorite ingredient is the marshmallow because it melts so smooth giving you that sticky but soft bite My nephew and I once teamed up to add roasted peanuts and everyone agreed it was even better than kettle corn movie nights just are not the same without a giant bowl of this on the coffee table
Storage Tips
Store the popcorn in airtight containers at room temperature to keep it from going stale For longer freshness pack it into zip top bags and squeeze out as much air as possible Avoid the fridge as it makes the popcorn chewy
Ingredient Substitutions
Try honey or maple syrup in place of the corn syrup for a slightly different flavor and natural sweetness If you are dairy free use a vegan butter substitute There are even plant based marshmallows that work just fine

Serving Suggestions
Pile this popcorn high in a big decorative bowl for parties Give as a sweet edible gift in cellophane bags tied with ribbons For movie nights I love adding a handful of mini pretzels or tossing in chocolate candies for a treat that disappears fast
Cultural and Historical Context
Caramel popcorn has its roots with old fashioned cracker jack but this version swaps out the classic cooked caramel for the stretchy soft comfort of marshmallow It is a distinctly American creation popping up at county fairs and home kitchens alike My grandma always said if you have marshmallows and popcorn you will never be bored
