Step‑by‑Step Instructions for Cotton Candy Marshmallows
Step 1: Prepare Gelatin
Begin by sprinkling three packets of unflavored gelatin over ½ cup of cold water in a large mixing bowl. Allow it to bloom for 5-10 minutes until it becomes spongy and thickens. This step is essential for achieving the soft, fluffy texture of your cotton candy marshmallows, so be patient!
Step 2: Make Sugar Syrup
In a medium saucepan, combine 1½ cups of granulated sugar, 1 cup of light corn syrup, and ½ cup of water. Heat over medium heat, stirring gently until the sugar dissolves completely. Once dissolved, increase the heat to high and bring the mixture to 240°F, using a candy thermometer for accuracy; watch for bubbling to indicate readiness.
Step 3: Mix Gelatin and Syrup
Once your sugar syrup reaches 240°F, carefully pour it over the bloomed gelatin while mixing on low speed with an electric mixer. Gradually increase the speed to high and beat for 10-12 minutes. You’ll notice the mixture transforming from liquid to a thick, fluffy marshmallow-like texture—this is the key moment to add in your cotton candy flavoring!
Step 4: Set the Marshmallows
Prepare a 9×9-inch pan by greasing it lightly and dusting it with a mixture of powdered sugar and cornstarch. Pour the thick marshmallow mixture into the pan, spreading it evenly with a spatula. Allow it to set at room temperature for a minimum of 6 hours, or ideally overnight, so it achieves the right firmness and flavor.
Step 5: Cut & Coat
After your marshmallows have set firmly, turn the pan onto a clean surface and cut the marshmallow into squares using a sharp knife or kitchen scissors. Dust each piece generously with additional powdered sugar and cornstarch to prevent sticking. Your delightful cotton candy marshmallows are now ready for fun and enjoyment!

Cotton Candy Marshmallows Recipe FAQs

What’s the best way to store cotton candy marshmallows?

What should I do if my marshmallow mixture doesn’t fluff up?
If the marshmallow doesn’t become fluffy, it could be due to incorrect sugar syrup temperature. Make sure the syrup reaches 240°F. Additionally, ensure you’re using a clean mixing bowl and equipment, as any grease can hinder the fluffiness.
