This homemade cotton candy marshmallow recipe transforms ordinary ingredients into pillowy, whimsical treats that capture the nostalgic flavor of fairgrounds and summer memories. The delicate sweetness and cloud-like texture make these the perfect handcrafted confection for anyone with a sweet tooth.
I first made these for my niece's birthday party, and the adults ended up enjoying them even more than the kids! Now they're requested at every family gathering, especially when we want to create something special without spending hours in the kitchen.
Ingredients
- Water: Divided into two portions provides the perfect medium for blooming gelatin and creating syrup
- Unflavored gelatin: Creates that signature bouncy marshmallow texture
- Granulated sugar: Forms the base sweetness without being overpowering
- Light corn syrup: Prevents crystallization and gives these marshmallows their silky smooth texture
- Salt: Enhances all the flavors and balances the sweetness
- Cotton candy flavoring: Delivers that authentic fairground taste you can't get any other way
- Gel food coloring: Allows for vibrant colors without thinning the mixture
- Powdered sugar: Prevents sticking and adds a delicate sweetness to the exterior
- Cornstarch: Works with the powdered sugar to create the perfect non stick coating
Step-by-Step Instructions
- Prepare the Pan:
- Line your baking pan with parchment paper and grease it lightly to ensure easy removal. The parchment should extend up the sides to create handles that will help you lift out the finished marshmallow slab. Take care to smooth out any wrinkles in the paper which could create indentations in your marshmallows.
- Bloom the Gelatin:
- Pour the cold water into your mixer bowl and sprinkle the gelatin evenly across the surface rather than dumping it in one spot. Allow it to sit undisturbed for the full 10 minutes if possible. This step is crucial as properly bloomed gelatin creates that distinctive marshmallow bounce and prevents graininess in the final product.
- Cook the Sugar Syrup:
- Combine your sugar ingredients in a heavy bottomed saucepan and stir gently only until the sugar dissolves. Once you bring it to a boil, avoid stirring which can cause crystallization. Instead, gently swirl the pan if needed. Use a pastry brush dipped in water to wash down any sugar crystals that form on the sides of the pan. The precise temperature of 240°F is essential for perfect marshmallow consistency.
- Whip the Marshmallow Mixture:
- Start your mixer on the lowest setting possible before pouring in the hot syrup to avoid splashing. Pour the syrup in a thin stream between the beater and the side of the bowl, not directly onto the beater. The transformation is magical as the mixture expands to nearly triple its original volume. You'll know it's ready when the bowl feels barely warm to the touch and the mixture forms soft peaks that hold their shape.
- Transfer to the Pan:
- Work quickly as the mixture begins setting fast. Pour all at once into the center of your prepared pan and use a greased offset spatula to gently push it into corners. For a smooth top, dip your spatula in warm water between strokes. If adding swirls of color, drizzle different shades on top and use a toothpick to create patterns before the surface sets.
- Cut and Coat the Marshmallows:
- The powdered sugar mixture is your best friend here. Be generous with it on your cutting surface, your hands, and your cutting tools. For clean cuts, rinse your knife in hot water and dry it between slices. If using cookie cutters, dip them in the powdered sugar mixture first to prevent sticking.

The cotton candy flavoring is truly what makes these special. I discovered it during a baking supply shopping spree and have been incorporating it into everything from frosting to meringues. My family particularly loves when I make these in blue and pink swirls which reminds everyone of the mixed cotton candy cones from county fairs.
Storage Tips
These homemade marshmallows stay fresh longer than you might expect. Store them in an airtight container at room temperature with parchment paper between layers to prevent sticking. They'll maintain their perfect texture for up to two weeks, though they rarely last that long in my house! Avoid refrigerating marshmallows as this can make them sweat and become sticky.
Flavor Variations
While cotton candy creates that fairground magic, this recipe works beautifully with endless flavor combinations. For a sophisticated twist, try replacing the cotton candy flavoring with 1 teaspoon of vanilla bean paste and 2 tablespoons of bourbon. For a tropical version, use coconut extract and roll the finished marshmallows in toasted coconut flakes instead of the powdered sugar mixture. Peppermint extract with red swirls makes perfect holiday treats.
Serving Suggestions
These marshmallows elevate even the simplest hot chocolate into a special occasion drink. Cut them into tiny cubes to use as an ice cream topping where they'll slowly melt into the cold cream. For an elegant dessert, dip them halfway in melted chocolate and sprinkle with edible glitter. They also make beautiful gifts when packaged in cellophane bags with colorful ribbons.
