Ingredients

• 10 cups freshly popped popcorn plain, unsalted

• ¼ cup light corn syrup
• ¼ cup sweetened condensed milk
• ½–1½ tsp cotton candy flavoring to taste
• a pinch of salt

Instructions

Prepare the popcorn

• Place popcorn in a large bowl and remove any unpopped kernels.

Melt the coating

• In a saucepan over low heat, melt butter.
• Add 4 cups marshmallows + corn syrup.
• Stir constantly until fully melted and smooth.
• Whisk in sweetened condensed milk.

Flavor it

• Remove from heat. Stir in cotton candy flavoring and salt.
• Divide mixture into two bowls if using food coloring, tint one pink and one blue.

Coat the popcorn

• Drizzle the coating over the popcorn, alternating colors if desired. Toss gently until evenly coated.

Cool slightly

• Let popcorn cool for 5–10 minutes so it’s no longer hot.

Add marshmallows & mix-ins

• Fold in mini marshmallows and any optional add-ins.

Set (optional)

• Spread onto a parchment-lined baking sheet and let set for 15–20 minutes before serving.

Notes

• Use plain popcorn: Start with unsalted, unbuttered popcorn so the cotton candy flavor shines without becoming overly salty.
• Low heat is key: Melt the coating gently to prevent scorching.
• Flavor gradually: Cotton candy flavoring can be strong, so add a little at a time and taste before adding more.
• Cool before marshmallows: If adding extra marhsmallows, let the popcorn cool slightly so the marshmallows don’t melt completely when mixed in.
• Color is optional: Pastel pink and blue add visual charm, but the popcorn tastes just as good without food coloring.
• Add cotton candy last: If using real cotton candy, sprinkle it on right before serving since it melts quickly.
• Storage tip: Store in an airtight container at room temperature for up to 2 days for best texture and flavor.

❓ FAQ – Cotton Candy Popcorn with Marshmallows

Can I make this popcorn without food coloring?
Yes. The popcorn will still have cotton candy flavor without coloring; it just won’t have the pastel pink-and-blue look.

What kind of cotton candy flavoring works best?
Clear cotton candy flavoring designed for baking or candy-making works best because it won’t discolor the coating.

Will the marshmallows get hard?
They stay soft if added after the popcorn has cooled slightly. If added too early, they may melt into the coating.

Can I package this for gifts?
Absolutely. Once fully set, portion into cellophane bags or jars and seal tightly for gifting or party favors.

How long does cotton candy popcorn stay fresh?
It’s best enjoyed within 1–2 days, but it can stay fresh up to 3 days when stored in an airtight container.

Can I add other candies or mix-ins?
Yes. White chocolate chips, pastel candies, sprinkles, or cereal pieces all pair well with the cotton candy flavor.

Is this recipe safe for kids to help make?
Yes, with supervision during the melting step. Kids can help toss the popcorn and add marshmallows and decorations.
