Gooey Marshmallow Caramel Popcorn: The Ultimate Sweet Snack Obsession

Few snacks capture pure joy quite like Gooey Marshmallow Caramel Popcorn. It’s sticky, buttery, sweet, and unapologetically indulgent. Every handful delivers a perfect balance of crunchy popcorn, rich homemade caramel, and soft, stretchy marshmallow that pulls into irresistible strands. This is not your average movie-night popcorn. This is the kind of treat that disappears from the bowl faster than you expect and leaves everyone asking for the recipe.

Whether you’re making it for a cozy night in, a holiday party, a bake sale, or gifting in cute jars, this marshmallow caramel popcorn checks all the boxes. It’s nostalgic yet elevated, simple yet impressive, and endlessly customizable. Best of all, it’s made entirely at home with pantry-friendly ingredients, no candy thermometer required.

This recipe focuses on gooey texture, not hard caramel crunch. The marshmallows melt directly into the warm caramel, creating a soft, chewy coating that clings lovingly to each kernel. The result is popcorn that stays tender for days instead of turning tooth-breakingly hard.

Let’s dive deep into everything you need to know to master this crowd-pleasing snack.


Why Gooey Marshmallow Caramel Popcorn Is So Addictive

There’s actual food science behind why this popcorn is impossible to stop eating. Caramel alone provides sweetness and richness, but when marshmallows are introduced, they add elasticity and moisture. The sugars in the marshmallows prevent the caramel from fully hardening, keeping the coating soft and chewy.

Texturally, you get:

  • Crunch from freshly popped popcorn
  • Creaminess from butter
  • Deep sweetness from brown sugar
  • Stretchy gooeyness from marshmallows

Flavor-wise, vanilla enhances everything, while a touch of salt keeps the sweetness balanced and sophisticated.

This combination is why marshmallow caramel popcorn feels luxurious despite being incredibly easy to make.


Ingredients You’ll Need

  • Popcorn kernels – freshly popped for best texture
  • Unsalted butter – adds richness and smooth mouthfeel
  • Brown sugar – provides deep caramel flavor
  • Light corn syrup – ensures glossy, smooth caramel
  • Salt – balances sweetness
  • Baking soda – creates lightness in the caramel
  • Vanilla extract – enhances overall flavor
  • Mini marshmallows – melt quickly and evenly

Step-by-Step Instructions

  1. Pop popcorn using your preferred method and remove all unpopped kernels. Place popcorn in a very large heatproof bowl.
  2. In a saucepan over medium heat, melt butter completely.
  3. Add brown sugar, corn syrup, and salt. Stir until combined.
  4. Bring mixture to a gentle boil and cook for 4–5 minutes, stirring occasionally, until thickened and glossy.
  5. Remove from heat and immediately stir in baking soda and vanilla extract. The caramel will foam slightly.
  6. Add marshmallows to the hot caramel and stir until partially melted and gooey.
  7. Pour the caramel-marshmallow mixture over the popcorn.
  8. Gently fold until every kernel is evenly coated.
  9. Let cool slightly before serving for maximum gooeyness.

Pro Tips for Perfect Gooey Popcorn

  • Use fresh popcorn, not pre-bagged
  • Stir gently to avoid crushing kernels
  • Work quickly once marshmallows are added
  • Store loosely covered to maintain softness

Delicious Variations

  • Chocolate Drizzle: Add melted chocolate on top

Storage & Shelf Life

Store in an airtight container at room temperature for up to 3 days. Avoid refrigeration, as it hardens the caramel.
