Marshmallow Popcorn Treat

Featured in Appetizers & Snacks.

This easy marshmallow popcorn snack uses melted marshmallows with brown sugar and butter to create a soft, chewy coating. Unlike crunchy caramel corn that gets baked, this no-bake version is faster and simpler. Corn syrup keeps the caramel smooth, while vanilla gives it a rich taste. Great for snacks, parties, or whenever you're craving something sweet. It’s beginner-friendly and needs only a few basic ingredients.

When making the best marshmallow caramel popcorn, getting the timing and heat just right is everything. After tweaking this snack through countless family gatherings, I've found that the trick is in how you blend the caramel with those marshmallows. What you'll get is a stretchy, sweet snack that perfectly balances the gooey marshmallow with rich buttery caramel notes.

I whipped this up during our movie night last week, and seeing everyone's fingers get all sticky as they couldn't stop grabbing more reminded me what makes this treat so fun. I found out that cooking the sugar just right - long enough for flavor but not so long it gets hard - was the game-changer.

Key Ingredients

  • Popcorn: Pop it fresh for the crunchiest results.
  • Brown Sugar: Go with dark for extra flavor or light for a milder touch.
  • Corn Syrup: This gives you that perfect gooey consistency.
  • Butter: Pick unsalted so you can manage how salty it turns out.
  • Vanilla Extract: The real stuff works way better than imitation.
  • Marshmallows: Big or small ones work great - your choice.

Step-by-Step Cooking Guide

Getting Your Popcorn Ready
Pop your kernels however you like to do it. Take out any unpopped ones so nobody breaks a tooth. Put your popcorn in a big bowl that won't melt when hot stuff goes in. You'll need plenty of room for mixing. Keep it nearby.
Making Your Caramel Mix
Put butter in a pot over medium heat until it melts. Throw in your brown sugar and corn syrup. Keep stirring until all the sugar melts away. Let it bubble for about 3-4 minutes. Don't let it get too dark. Keep the heat steady the whole time.
Adding The Marshmallows
Turn the heat down low. Dump in all your marshmallows at once. Use a wooden spoon and keep stirring. Melt them completely into the caramel mix. Splash in some vanilla and stir it up. You want it smooth and shiny.
Mixing It All Together
Pour your gooey mixture over the popcorn right away. Grab two big spoons and start folding it all together. Work fast before it cools down. Keep turning the popcorn until every piece gets coated. Break up any big chunks you see.
Letting It Set
Spread everything out on a baking sheet lined with parchment. Pull apart any clusters if you want smaller bits. Let it cool just sitting out. Don't stick it in the fridge or it'll get too hard. Give it about half an hour to firm up.

After making this sticky snack so many times, I can tell you that getting all your stuff ready beforehand really helps you nail that perfect stretchy texture every time.

Tasty Twists To Consider

Toss in some nuts, broken pretzels, or chocolate chips with your coated popcorn for extra crunch and flavor. A sprinkle of sea salt right after mixing gives you that amazing sweet-salty combo.

Keeping It Fresh

Keep it in a sealed container at room temp for up to 3 days. Put some parchment between layers so they don't stick together. Skip the fridge - it'll just make your popcorn too hard to enjoy.

Serving At Gatherings

For your next get-together, roll some paper into cones for personal portions, or set up a fun popcorn station where friends can add their own favorite toppings.

This marshmallow caramel popcorn has turned into my go-to snack for movie nights. It shows that sometimes the best treats are just clever twists on snacks we already love.
