These homemade cotton candy marshmallows will steal the show at any gathering and add a burst of nostalgia to dessert tables. Fluffy and bursting with classic carnival flavor, they are shockingly easy to make at home with just a handful of ingredients and a bit of patience for the set time. My favorite part is swirling vibrant pink and blue for a playful treat that delights both kids and adults. Whenever I serve them at birthday parties, guests can't believe they are homemade.

These were a huge success at my daughter's birthday and now they’re often requested for school celebrations and holidays. Kids love the soft texture and grownups are always wowed by the fun flavor twist.

Ingredients

  • Powdered gelatin: gives that authentic bouncy marshmallow structure Use unflavored and check it is fresh for best results
  • Cold water: is needed to bloom the gelatin Aim for cold tap that feels fresh
  • Granulated sugar: sweetens and structures the marshmallow Use fine white sugar for best dissolving
  • Light corn syrup: prevents crystallization Choose clear corn syrup for the fluffiest results
  • Kosher salt: is added for balance A pinch goes a long way and brightens flavor
  • Cotton candy flavoring: brings the signature taste Look for high quality flavoring oils for intensity I use LorAnn brand for most authentic results
  • Pink and blue food coloring: creates eye catching swirls Gel food coloring gives the brightest hue but water based will work
  • Powdered sugar: keeps marshmallows from sticking It also adds extra softness to the outside

Instructions

Bloom the Gelatin:
Whisk the powdered gelatin with half of the cold water in the bowl of a stand mixer Allow the mixture to stand about eight to ten minutes until it becomes thickened and slightly opaque This step is key for proper marshmallow texture
Cook the Syrup:
While the gelatin blooms Combine the remaining water granulated sugar corn syrup and salt in a saucepan over medium heat Whisk constantly and allow the mixture to simmer for six to eight minutes It will turn clear and look glossy Remove from the heat before it starts to color
Combine and Whip the Mixture:
Using a whisk attachment Set your mixer to low Pour the hot sugar mixture gently into the bloomed gelatin Mix for about one minute until blended then increase to high Speed matters here Whip for ten minutes until the mixture is white fluffy and nearly tripled in volume
Add Flavor and Color:
Pour in the cotton candy flavoring Continue whisking for another minute Divide the fluffy marshmallow into two bowls and add pink food coloring to one and blue to the other Gently stir for vivid swirls
Fill and Dust the Pan:
Dust a nine by thirteen inch baking pan with powdered sugar Spoon in the colored marshmallows in alternating swirls Use a spatula to smooth the top Dust with extra powdered sugar Cover with plastic wrap Let it set at room temperature for eight to twelve hours This slow set makes the texture soft
Cut and Serve:
Remove the marshmallow slab from your pan and gently transfer to a board Dust with more powdered sugar Cut into one inch squares or use cookie cutters for shapes Serve and enjoy the magic

My favorite part about these is the fun customization The first time I made these for my niece we let her choose the colors so every batch can be different I can still remember her sticky hands and bright smile while cutting the marshmallows into star shapes with cookie cutters

Ingredient Swaps

Not everyone has cotton candy flavoring on hand You can swap in vanilla extract or raspberry flavor for a twist If you do not have gelatin packets measure powdered gelatin for more precise results If you want a vegetarian option look for a quality agar agar substitute though results may be slightly denser

Ingredients You’ll Need

→ Marshmallow Base

01 2.5 tablespoons powdered gelatin
02 240 millilitres cold water, divided
03 300 grams granulated sugar
04 180 millilitres light corn syrup
05 0.5 teaspoon kosher salt
06 2 teaspoons cotton candy flavouring
07 Pink food colouring
08 Blue food colouring
09 90 grams powdered sugar

How to Make It

Step 01

In the bowl of a stand mixer, whisk powdered gelatin with half of the cold water and allow to stand for 8–10 minutes to bloom.

Step 02

Whisk together the remaining water, granulated sugar, corn syrup, and kosher salt in a medium saucepan over medium heat. Simmer for 6–8 minutes, whisking constantly, until the mixture becomes translucent. Remove from heat.

Step 03

With the mixer on low and using a whisk attachment, slowly stream the hot sugar mixture into the bloomed gelatin. Once fully combined, continue whisking on low for 1 minute.

Step 04

Increase stand mixer speed to high and whisk for 10 minutes until a thick, fluffy white mixture forms.

Step 05

Reduce the mixer speed to low, add cotton candy flavouring, and mix for 1 minute. Divide mixture evenly into two bowls and tint one pink and the other blue with food colouring.

Step 06

Dust a 23 x 33 centimetre baking pan with half of the powdered sugar. Alternately spoon coloured marshmallow mixtures into the pan. Level the top with a rubber spatula and dust the surface with remaining powdered sugar. Cover with plastic wrap and let set at room temperature for 8–12 hours.

Step 07

Once firmly set, transfer the marshmallow slab to a cutting board. Dust away excess powdered sugar and cut into 2.5 centimetre squares. Serve and enjoy.

Extra Tips

  1. For vivid colour, use gel-based pink and blue food colouring. Water-based colourings will yield paler results.
  2. Cut marshmallows into classic squares or use a cookie cutter for assorted shapes.
  3. For best freshness, store marshmallows in an airtight container at room temperature for up to 1 month or freeze for up to 3 months.
