There’s something magical about homemade marshmallows—they’re soft, pillowy, and melt-in-your-mouth delicious. But when you add cotton candy flavor? That’s when the real fun begins! These Cotton Candy Marshmallows are a whimsical twist on the classic treat, bringing back childhood memories of carnival treats and sticky-sweet happiness.
I love making these because they’re surprisingly simple (no fancy equipment needed!) and the pastel colors make them perfect for parties, gifts, or just a fun baking project. The cotton candy flavor adds a nostalgic touch, while the light, airy texture keeps you coming back for more. Trust me, once you try these, store-bought marshmallows will never compare!
What You Need To Make This Recipe
Gelatin: This is the key ingredient that gives marshmallows their signature bounce. Unlike regular gelatin sheets, powdered gelatin dissolves easily and sets perfectly for that fluffy texture.
Granulated sugar: Sugar sweetens the marshmallows and helps create a stable structure when whipped with the gelatin. It also gives them that classic marshmallow chewiness.
Corn syrup: This prevents the sugar from crystallizing, ensuring smooth, glossy marshmallows. Light corn syrup works best, but you can also use golden syrup as a substitute.
Cotton candy flavoring: This is what gives the marshmallows their nostalgic carnival taste. A few drops go a long way—look for high-quality flavoring oils (not extracts) for the best results.
Food coloring (optional): Pastel pink and blue are classic cotton candy colors, but you can use any shade you like. Gel food coloring works best since it won’t thin out the mixture.
Powdered sugar & cornstarch: This combo keeps the marshmallows from sticking when you cut them. A light dusting is all you need for perfectly shaped treats.
Ingredients List
- 3 packets (21g) unflavored powdered gelatin
- 1 cup (240ml) cold water, divided
- 1 ½ cups (300g) granulated sugar
- 1 cup (240ml) light corn syrup
- ¼ tsp salt
- 1 tsp cotton candy flavoring
- Pink and blue gel food coloring (optional)
- ½ cup (60g) powdered sugar
- ½ cup (60g) cornstarch
How to Make Cotton Candy Marshmallows
Step 1: Bloom the Gelatin
In a large mixing bowl, sprinkle the gelatin over ½ cup of cold water. Let it sit for 5-10 minutes until it becomes thick and spongy. This process, called “blooming,” helps the gelatin dissolve smoothly later.
Step 2: Cook the Sugar Syrup
In a saucepan, combine the remaining ½ cup water, granulated sugar, corn syrup, and salt. Cook over medium heat, stirring until the sugar dissolves. Then, stop stirring and let it boil until it reaches 240°F (115°C) on a candy thermometer.
Step 3: Whip the Marshmallow Base
Carefully pour the hot syrup into the bloomed gelatin while mixing on low speed. Once combined, increase speed to high and whip for 10-12 minutes until thick, glossy, and tripled in volume.
Step 4: Add Flavor & Color
Mix in the cotton candy flavoring. If using food coloring, divide the mixture into two bowls and tint one pink and one blue (or swirl them together for a marbled effect).
Step 5: Set & Cut
Pour the marshmallow mixture into a parchment-lined pan dusted with powdered sugar and cornstarch. Let it set at room temperature for 4-6 hours (or overnight). Once firm, cut into squares and coat each piece in more powdered sugar mixture.
Tips for Making This Recipe
- Use a stand mixer if possible—the marshmallow fluff gets very thick!
- For extra flavor, add a pinch of vanilla extract along with the cotton candy flavoring.
- If the marshmallow is too sticky when cutting, lightly oil your knife.
- Store in an airtight container for up to 2 weeks.
- For fun variations, try rolling the marshmallows in sprinkles or dipping them in chocolate.
FAQs
Can I use marshmallow fluff instead?
No, this recipe requires making marshmallows from scratch for the right texture.
What if I don’t have a candy thermometer?
You can test the syrup by dropping a small amount in cold water—if it forms a soft ball, it’s ready.
Can I make these vegan?
Yes! Substitute gelatin with agar-agar (use 2 tsp dissolved in water) and replace corn syrup with rice syrup.
Why are my marshmallows sticky?
This usually means they need more setting time or weren’t coated enough in powdered sugar.
Can I freeze marshmallows?
Yes! Freeze in an airtight container for up to a month, but they’re best enjoyed fresh.
These Cotton Candy Marshmallows are a delightful, fluffy treat that’s sure to impress. Whether you’re making them for a party or just because, they’re a fun, sweet project with delicious results! 🍬✨
