Ingredients for Cotton Candy Marshmallows
To make the best cotton candy marshmallows, gather the following ingredients:
- 3 envelopes unflavored gelatin (about 2 1/2 tablespoons)
- 1/2 cup cold water (for blooming gelatin)
- 1 1/2 cups granulated sugar
- 1/2 cup corn syrup
- 1/2 cup water (for sugar syrup)
- 1 teaspoon cotton candy flavoring (available at specialty baking stores or online)
- Food coloring (optional for vibrant marshmallows)
- 1/2 cup powdered sugar (for dusting)
- 1/4 cup cornstarch (for dusting)
Step-by-Step Guide to Making Cotton Candy Marshmallows
1: Prepare the Gelatin
In a large mixing bowl, sprinkle the unflavored gelatin over 1/2 cup of cold water. Let it bloom for 5 minutes to absorb the liquid fully.
2: Cook the Sugar Syrup
In a saucepan, combine 1 1/2 cups granulated sugar, 1/2 cup corn syrup, and 1/2 cup water. Heat the mixture over medium-high heat until it reaches 240°F (115°C) on a candy thermometer. This step ensures the right marshmallow texture.
3: Combine and Whip
Carefully pour the hot sugar syrup into the bloomed gelatin while mixing on low speed. Increase to medium-high and whip for 10-15 minutes until the mixture becomes thick, glossy, and tripled in volume.
4: Add Cotton Candy Flavor
Add 1 teaspoon of cotton candy flavoring and a few drops of food coloring (if desired). Continue whipping until fully incorporated.
5: Set the Marshmallows
Grease a 9×9-inch baking pan and line it with parchment paper. Pour in the marshmallow mixture, smoothing the top with a spatula. Let it set at room temperature for at least 4 hours (or overnight) until firm.
6: Cut and Dust
Mix 1/2 cup powdered sugar and 1/4 cup cornstarch in a bowl. Dust the marshmallow surface, then cut into squares using a greased knife or scissors. Toss the pieces in the sugar mixture to prevent sticking.
Tips for Perfect Cotton Candy Marshmallows
- Bloom the Gelatin Properly: Allowing the gelatin to bloom fully ensures the marshmallows will set correctly.
- Use a Candy Thermometer: Precision is key! Ensure the sugar syrup reaches exactly 240°F.
- Customize the Colors: Experiment with different food colorings for a playful, cotton candy-inspired look.
- Storage Matters: Keep your marshmallows in an airtight container at room temperature for up to 2 weeks.

Frequently Asked Questions (FAQs)
1. Can I make cotton candy marshmallows without corn syrup?
Yes, but corn syrup helps prevent sugar crystallization. As an alternative, you can use honey or golden syrup, though the texture may vary.
2. How do I keep marshmallows from sticking together?
Coat the marshmallows with a powdered sugar and cornstarch blend after cutting to avoid stickiness.
3. Can I freeze cotton candy marshmallows?
Absolutely! Freeze marshmallows in a single layer, then transfer to an airtight container. Allow to thaw at room temperature before serving.
4. Can I make these marshmallows without a candy thermometer?
It’s possible, but using a thermometer ensures accuracy. Without one, test the syrup by dropping it into cold water; it should form a soft ball.
