Cotton candy marshmallows are a whimsical twist on a classic treat, blending the fluffy texture of marshmallows with the nostalgic flavor of cotton candy. Perfect for parties, movie nights, or simply satisfying a sweet craving, these homemade marshmallows are as fun to make as they are to eat. With their vibrant colors and playful taste, they’re sure to bring a smile to anyone’s face.

I’ve made these marshmallows several times, and they never fail to impress. The first time I served them at a family gathering, the kids couldn’t get enough, and the adults were equally delighted by the nostalgic flavor.

Key Ingredients and Their Roles

  • Unflavored Gelatin: This is the backbone of the recipe, giving the marshmallows their signature fluffy and airy texture.
  • Granulated Sugar: Adds sweetness and helps create the structure of the marshmallows.
  • Corn Syrup: Keeps the marshmallows smooth and prevents crystallization, ensuring a perfect consistency.
  • Water: Used to dissolve the gelatin and sugar, creating the base for the marshmallow mixture.
  • Cotton Candy Flavoring: This is what gives the marshmallows their signature carnival-inspired taste. Look for high-quality flavoring for the best results.
  • Powdered Sugar and Cornstarch: A dusting of this mixture prevents the marshmallows from sticking together and adds a light, sweet finish.

Crafting Your Cotton Candy Marshmallows

Bloom the Gelatin

Start by sprinkling unflavored gelatin over 1/2 cup of water in a large bowl. Let it sit for about 5 minutes to bloom. This step is crucial because it allows the gelatin to absorb the water and swell, which is essential for achieving the right texture.

Cook the Sugar Syrup

In a medium saucepan, combine granulated sugar, corn syrup, and water. Heat the mixture over medium-high heat until it reaches 240°F (115°C) on a candy thermometer. This temperature is key to creating the perfect marshmallow consistency.

Combine and Whip

Once the sugar syrup is ready, carefully pour it into the bloomed gelatin while stirring continuously. Use a stand mixer or hand mixer to beat the mixture on medium speed for 10-15 minutes until it becomes thick, glossy, and fluffy. This step is where the magic happens, transforming the liquid into a light, airy marshmallow base.

Add Flavor and Color

When the mixture reaches the right consistency, add the cotton candy flavoring. If you want to make the marshmallows visually appealing, add a few drops of food coloring to match the cotton candy theme.

Set and Shape

Pour the marshmallow mixture into a greased 9x9-inch baking pan. Smooth the top with a spatula and let it set at room temperature for at least 4 hours, or until firm.

Cut and Dust

Once set, dust the marshmallows with a mixture of powdered sugar and cornstarch. Cut them into squares or fun shapes using a knife or kitchen scissors.

I personally love using pink cotton candy flavoring because it reminds me of childhood fairs. My family adores these marshmallows, and they’ve become a staple at our summer gatherings.

Serving Ideas

Sweet Pairings

Serve these marshmallows alongside other nostalgic treats like popcorn, chocolate, or even as a topping for hot cocoa. They also make a delightful addition to ice cream sundaes or milkshakes.

Party Perfect

Create a cotton candy-themed dessert table by arranging the marshmallows in decorative jars or bowls. For a fun twist, skewer them onto sticks for a carnival-inspired treat.

On-the-Go Snacks

Pack individual marshmallow squares in small bags or containers for a quick and easy party favor or snack.

Creative Variations

Dietary Tweaks

For a vegan version, swap the gelatin for agar-agar and use a plant-based cotton candy flavoring.

Flavor Experiments

Try mixing different cotton candy flavors, like blue raspberry and vanilla, for a unique taste. You can also add a hint of vanilla extract for extra depth.

Color Play

Use natural food coloring to create pastel shades or go bold with vibrant hues for a rainbow effect.

Storing and Reheating

Airtight Storage

Keep your marshmallows fresh by storing them in an airtight container. A glass jar or resealable plastic bag works well.

Avoid Humidity

Store them in a cool, dry place to prevent them from becoming sticky.

Freezing Option

For longer storage, freeze the marshmallows in a single layer on a baking sheet, then transfer them to an airtight container. Thaw at room temperature before serving.

Cotton candy marshmallows are more than just a treat—they’re a nostalgic experience that brings joy to every bite. Whether you’re making them for a party, a gift, or simply to indulge your sweet tooth, these marshmallows are a delightful way to add a touch of whimsy to your day. Give this recipe a try, and let the magic of cotton candy take you back to simpler, sweeter times.

Ingredients

01 3/4 cup (180 ml) cold water, divided
02 3 envelopes (7 g each) unflavored gelatin
03 2 cups (400 g) granulated sugar
04 1/2 cup (120 ml) light corn syrup
05 1/4 teaspoon salt
06 1 teaspoon cotton candy flavoring (available online or in baking stores)
07 Gel food coloring (pink, blue, or any color of your choice)
08 1/2 cup (65 g) powdered sugar
09 1/4 cup (30 g) cornstarch

Instructions

Step 01

Line a 9×9-inch (23×23 cm) baking pan with parchment paper. Lightly grease it with cooking spray or a thin layer of oil.

Step 02

In the bowl of a stand mixer, combine 1/2 cup of cold water and the gelatin. Let it sit for 5–10 minutes to bloom.

Step 03

In a medium saucepan, combine the granulated sugar, corn syrup, salt, and the remaining 1/4 cup of water. Heat over medium heat, stirring until the sugar dissolves. Increase the heat to medium-high and bring to a boil. Cook until the mixture reaches 240°F (115°C) on a candy thermometer.

Step 04

Turn the mixer on low speed and carefully pour the hot sugar syrup into the bloomed gelatin. Gradually increase the speed to high and beat for 10–12 minutes, or until the mixture is thick, fluffy, and slightly cooled. Add the cotton candy flavoring and a few drops of food coloring. Mix until evenly combined.

Step 05

Pour the marshmallow mixture into the prepared pan. Smooth the top with a greased spatula. Let the marshmallows sit at room temperature for 6–8 hours, or overnight, to set.

Step 06

In a small bowl, mix the powdered sugar and cornstarch. Dust a work surface with the mixture. Turn the marshmallow slab out onto the surface, peel off the parchment paper, and dust the top with the powdered sugar mixture. Use a greased knife or cookie cutters to cut the marshmallows into squares or shapes. Toss the cut marshmallows in the powdered sugar mixture to coat.

Step 07

Store in an airtight container at room temperature for up to 1 week.
