Prep: 10 min
Cook: 10 min
Servings: 8
Ingredients
- 8 cups freshly popped popcorn (plain, unsalted)
- ½ cup (1 stick) unsalted butter
- 1 cup packed light brown sugar
- 3 cups mini marshmallows
- ¼ cup light corn syrup
- 1 teaspoon pure vanilla extract
- ¼ teaspoon salt
- ½ teaspoon baking soda (optional, for a lighter caramel coating)
Optional Additions
- ½ cup white chocolate chips
- ½ cup chopped pecans or peanuts
- Extra mini marshmallows
- A pinch of flaky sea salt
Step-by-Step Instructions
Step 1: Prepare the Popcorn
Pop enough popcorn to make approximately 8 cups.
Transfer the popcorn to a large mixing bowl, removing any unpopped kernels.
If using microwave popcorn, choose plain or lightly salted popcorn without extra butter flavoring.
Line a large baking sheet with parchment paper and set aside.
Step 2: Melt the Butter
Place a medium saucepan over medium-low heat.
Add the unsalted butter and allow it to melt completely, stirring occasionally.
Avoid browning or burning the butter.
Step 3: Make the Caramel Base
Add the packed brown sugar, light corn syrup, and salt to the melted butter.
Stir continuously until the sugar dissolves and the mixture becomes smooth.
Bring the mixture to a gentle simmer and cook for approximately 2 minutes, stirring frequently.
The caramel should become glossy and slightly thickened.
Step 4: Add the Marshmallows
Reduce the heat to low.
Add the mini marshmallows to the warm caramel mixture.
Stir slowly and continuously until the marshmallows melt completely and blend into the caramel.
The mixture should become thick, creamy, smooth, and glossy.
Remove the saucepan from the heat.
Step 5: Add Vanilla
Stir in the vanilla extract.
If using baking soda, add it now and stir gently. The mixture will foam slightly, producing a lighter coating.
Be careful when handling the hot caramel, as it can cause burns.
Step 6: Coat the Popcorn
Immediately pour the warm marshmallow caramel mixture over the prepared popcorn.
Using a silicone spatula or large wooden spoon, gently fold the popcorn into the coating.
Continue mixing until the popcorn is evenly covered with the creamy caramel-marshmallow glaze.
Work quickly because the mixture will begin to thicken as it cools.
Step 7: Spread and Cool
Transfer the coated popcorn onto the prepared parchment-lined baking sheet.
Spread it gently into an even layer.
Allow the caramel corn to cool for approximately 15–20 minutes.
For a softer, gooier texture, serve while slightly warm.
For a firmer, chewier texture, allow it to cool completely.
Step 8: Serve and Enjoy
Gently break the caramel corn into bite-sized clusters.
Transfer it to a large serving bowl.
If desired, drizzle with melted white chocolate or sprinkle with a little flaky sea salt.
Serve and enjoy your delicious homemade Marshmallow Caramel Corn!
Tips for Perfect Marshmallow Caramel Corn
1. Use Fresh Popcorn
Freshly popped popcorn produces the best flavor and texture. Avoid stale popcorn because it can become chewy after coating.
2. Melt Marshmallows Slowly
Always reduce the heat before adding marshmallows. High heat can scorch them or make the mixture overly sticky.
3. Don’t Overcook the Caramel
A short, gentle simmer is enough. Cooking the caramel too long may create a harder coating instead of a soft, chewy one.
4. Work Quickly
The marshmallow caramel thickens as it cools. Pour and stir immediately for even coverage.
5. Adjust the Sweetness
Add a small pinch of sea salt to balance the rich sweetness of the brown sugar and marshmallows.
6. Use a Large Mixing Bowl
A large bowl makes it much easier to mix the popcorn without crushing it.
Delicious Variations
Chocolate Marshmallow Caramel Corn
Drizzle melted milk chocolate or dark chocolate over the cooled popcorn.
Salted Caramel Popcorn
Sprinkle flaky sea salt over the popcorn immediately after coating.
Peanut Butter Marshmallow Popcorn
Stir ¼ cup creamy peanut butter into the warm caramel before adding the marshmallows.
Holiday Marshmallow Popcorn
Add red and green sprinkles after the coating has cooled slightly for a festive Christmas treat.
Nutty Caramel Corn
Mix in chopped pecans, almonds, or peanuts for extra crunch.
Storage Instructions
Room Temperature: Store cooled popcorn in an airtight container for up to 3 days for the best texture.
Refrigerator: Not recommended because refrigeration can make the popcorn damp and sticky.
Freezer: Freezing is not recommended for this soft marshmallow version.
Best Serving Time: Enjoy within the first 24 hours for the freshest, softest texture.

Frequently Asked Questions
Can I make Marshmallow Caramel Corn without corn syrup?
Yes. You can substitute honey, although it will slightly change the flavor and texture. Corn syrup helps keep the caramel smooth and reduces crystallization.
Can I use large marshmallows instead of mini marshmallows?
Absolutely! Use approximately 150 g of regular marshmallows, cutting them into smaller pieces so they melt evenly.
Why is my caramel corn too sticky?
This recipe is designed to have a soft, gooey coating. If it is excessively sticky, allow it to cool longer before serving.
Can I bake this caramel corn?
This version is intended to remain soft and chewy, so baking isn’t necessary. Baking would change its texture.
Can I prepare it ahead of time?
Yes! Prepare it the day before serving and store it in an airtight container at room temperature.
