How to Make Marshmallow Popcorn

Caramel Marshmallow Popcorn takes just minutes to make!

POPCORN. Pop the popcorn and place it in a large bowl, remove unpopped kernels. Set aside.

CARAMEL. Melt the unsalted butter in a medium saucepan on medium heat. Add brown sugar and corn syrup until well blended. Add marshmallows and stir continuously on low heat until all melted.

COMBINE. Pour marshmallow mixture over popcorn and mix well. Spread popcorn on parchment paper or put it on a greased baking sheet and let set.

Recipe Tips

Amount in one bag of popcorn. One 3.28 oz bag of popcorn contains 5 tablespoons of un-popped kernels or about 11 cups of popped corn. There are 3 ways to get popcorn for this recipe:

  1. Buy 11 cups of plain pre-popped popcorn.
  2. Pop 5 tablespoons of your own kernels.
  3. Pop a bag of plain microwave popcorn. 

Marshmallows. Substitute large marshmallows for mini marshmallows with a 1:10 ratio. For this recipe use 200 mini marshmallows or about 3 cups. Either way, remember old marshmallows won’t melt well.

Corn syrup substitute. There are a few options though they may alter the taste, but not by much. Substitute a 1:1 ratio of maple syrup or honey. In the UK the closest substitute is “Golden Syrup”.

  • Make your own simple syrup: In a saucepan mix ¼ cup of water with 1 cup of granulated sugar. Simmer until the sugar has melted and makes a syrup. 

Popcorn. Use any flavor of popcorn, but I prefer plain popcorn for this recipe. Kettle corn, salted popcorn, or lightly buttered popcorn work as well.

Don’t add extra popcorn or there won’t be enough caramel to hold them together. However, if you don’t add enough popcorn, the caramel will “melt” and it won’t hold its shape. 

Easy cleanup. Grease your hands with cooking spray before forming the balls to prevent sticking. 

Toppings. This popcorn really speaks for itself, but it can be fun to mix in a few colored sprinkles, little candies, chopped nuts, or mini chocolate chips. Do not add too many extras or the ratios will be off and the popcorn ball won’t stick together.

Storing Info

STORE all Marshmallow Popcorn together in an airtight container or wrap individual balls tightly with plastic wrap. The popcorn should last for 7-10 days at room temperature.

    1. A bag of un-popped popcorn is close to 3 ounces (around that). I’m not quite sure how much it is, popped.

    I used 1/2 unpopped kernels in my air popper and added a tablespoon of kosher salt, but I love the caramel and marshmallows together!

  5. Hi Kristyn, could I use marshmallow fluff? If so any idea how much? This looks sooo yummy, going to make & give as gifts for Christmas. Thank you! Have a wonderful holiday season!
