Instructions
Make the cotton candy syrup
- In a small saucepan, combine water and sugar. Heat over medium heat, stirring until the sugar fully dissolves. Remove from heat and let cool slightly. Stir in cotton candy extract and add a tiny amount of pink and blue food coloring if desired. Set aside to cool completely.
Blend the slushy
- Add ice, cold water, and cotton candy syrup to a blender. Blend until thick and icy but still pourable.
Assemble the floats
- Add 1 scoop of vanilla ice cream to each tall glass. Pour the cotton candy slushy over the ice cream until the glass is about ¾ full.
Top & serve
- Add another scoop of vanilla ice cream on top. Finish with whipped cream and fun toppings if desired.
Serve immediately
- Enjoy right now with a straw and spoon before it melts!
Notes
- Extract strength varies: Cotton candy extract can be very potent. Start with the lower amount and add more gradually to avoid an overpowering flavor.
- Syrup cooling: Let the syrup cool completely before blending so it doesn’t melt the ice too quickly.
- Slushy texture: Blend just until thick and icy; over-blending will turn it into a drink instead of a slush.
- Sweetness control: Adjust syrup amount based on personal preference and ice quantity.
- Color tip: Use gel food coloring for vibrant pastel color without thinning the syrup.
- Layering: Adding ice cream first helps create a classic float effect with foamy bubbles.
- Serve immediately: Slushy floats melt quickly and are best enjoyed right away.
- Make-ahead option: Syrup can be made ahead and stored refrigerated for up to 1 week.
💡 Tips & Variations
- Flavor control: Cotton candy extract is strong—add gradually and taste the syrup before using.
- Extra creamy: Replace half the water in the slushy with milk or half-and-half.
- Fizzy option: Use lemon-lime soda instead of water for a bubbly float.
- Pastel swirl look: Split syrup into two bowls, tint pink and blue, and drizzle separately when blending.
- Dairy-free: Use dairy-free vanilla ice cream.
