This marshmallow caramel popcorn brings together the best of sweet and salty in a quick 15-minute recipe.

The addition of corn syrup helps prevent crystallization, while vanilla extract adds depth of flavor. The result is a soft, chewy caramel corn that's perfect for movie nights, parties, or whenever you're craving a sweet treat.

Creating the perfect marshmallow caramel popcorn is all about timing and temperature. After perfecting this recipe through many movie nights and gatherings, I've discovered that the secret lies in how you melt and combine the caramel with the marshmallows. The result is a gooey, sweet treat that finds the perfect balance between sticky marshmallow and buttery caramel flavors.

Last weekend, I made this for a family movie night, and watching everyone's fingers get delightfully sticky as they reached for more reminded me why this treat is so special. The key was cooking the sugar mixture just long enough to develop flavor without hardening.

Essential Ingredients

  • Popcorn: Freshly popped gives the best texture and flavor.
  • Brown Sugar: Light or dark both work; dark gives a more robust flavor.
  • Corn Syrup: Creates the perfect sticky texture.
  • Butter: Unsalted gives you better control over flavor.
  • Vanilla Extract: Pure extract provides the best flavor.
  • Marshmallows: Regular size or mini both work well.

Detailed Cooking Instructions

Popcorn Preparation
Pop kernels using your preferred method. Remove all unpopped kernels carefully. Place popcorn in large bowl with room for mixing. Make sure bowl is heat-resistant. Set aside while preparing caramel mixture.
Caramel Base Creation
Melt butter in medium saucepan over medium heat. Add brown sugar and corn syrup. Stir continuously until sugar dissolves. Cook for 3-4 minutes until mixture bubbles. Don't let mixture darken too much. Maintain medium heat throughout process.
Marshmallow Integration
Reduce heat to low. Add marshmallows all at once. Stir continuously with wooden spoon. Melt marshmallows completely into caramel. Add vanilla extract and stir. Look for smooth, glossy consistency.
Coating Technique
Pour marshmallow caramel over popcorn immediately. Use two large spoons to fold and coat. Work quickly before mixture cools. Keep turning popcorn until evenly coated. Break up any large clumps.
Setting and Cooling
Spread on parchment-lined baking sheet. Separate into smaller clusters if desired. Let cool at room temperature. Don't refrigerate as it can become too hard. Allow to set for about 30 minutes.

Through many batches of this sticky treat, I've learned that having everything prepared before starting makes all the difference in achieving that perfect gooey texture.

Variations to Try

Add a cup of nuts, pretzel pieces, or chocolate chips to the coated popcorn for extra flavor and texture. Sprinkle with sea salt right after coating for a sweet-salty contrast.

Storage Solutions

Store in an airtight container at room temperature for up to 3 days. Place parchment paper between layers to prevent sticking. Don't refrigerate as it will become too hard.

Party Presentation

For gatherings, serve in paper cones for easy individual portions, or create a popcorn bar with different mix-ins guests can add themselves.

This marshmallow caramel popcorn has become my signature movie night treat. It proves that sometimes the most beloved recipes are those that bring a new twist to familiar favorites.
