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.
