Ingredients
- 3/4 cup (180 ml) cold water, divided
- 3 envelopes (7 g each) unflavored gelatin
- 2 cups (400 g) granulated sugar
- 1/2 cup (120 ml) light corn syrup
- 1/4 teaspoon salt
- 1 teaspoon cotton candy flavoring
- Gel food coloring (optional)
- 1/2 cup (65 g) powdered sugar
- 1/4 cup (30 g) cornstarch
Instructions
1. Prepare the Pan
Line a 9×9-inch (23×23 cm) baking pan with parchment paper and lightly grease it.
2. Bloom the Gelatin
In the bowl of a stand mixer, combine 1/2 cup of cold water with the gelatin. Let it sit for 5–10 minutes to bloom.
3. Make the Sugar Syrup
In a saucepan, combine sugar, corn syrup, salt, and the remaining 1/4 cup of water. Stir over medium heat until dissolved. Increase to medium-high and cook until it reaches 240°F (115°C) on a candy thermometer.
4. Whip the Marshmallow Base
With the mixer on low, slowly pour the hot syrup into the gelatin. Increase speed to high and beat for 10–12 minutes until thick, fluffy, and glossy. Mix in cotton candy flavoring and food coloring if using.
5. Set the Marshmallows
Pour the mixture into the prepared pan and smooth the top. Let sit uncovered at room temperature for 6–8 hours, or overnight.
6. Cut and Dust
Mix powdered sugar and cornstarch in a bowl. Turn the marshmallow slab onto a surface dusted with the mixture. Cut into squares or shapes, then toss in the sugar mixture to coat.

Can I use cotton candy syrup instead of flavoring?
Yes, but the texture may vary. Adjust sugar and water as needed.
Can I skip corn syrup?
Corn syrup helps with smoothness. You can substitute with honey or golden syrup, but the result may differ.
How do I add color?
Add gel food coloring during mixing. Swirl two colors for a tie-dye look.
