These cotton candy marshmallows put a playful spin on regular marshmallows, combining their soft, pillowy texture with the fun taste of cotton candy. They're great for gatherings, snacking during movies, or when you just want something sweet. Making these colorful treats at home is just as enjoyable as eating them, and they'll definitely put a grin on everyone's face.
I've whipped up these marshmallows many times now, and they always wow everyone. The first time I brought them to a family party, the little ones couldn't stop eating them, and surprisingly, the adults kept coming back for more too, loving that carnival taste.
Essential Components and What They Do
- Unflavored Gelatin: This works as the foundation, creating that bouncy, light feel marshmallows are known for.
- Granulated Sugar: Brings the sweetness and helps build the marshmallow structure.
- Corn Syrup: Makes sure your marshmallows stay silky and don't get grainy, giving them just the right texture.
- Water: Helps melt the gelatin and sugar, forming the base of your marshmallow mix.
- Cotton Candy Flavoring: This gives your treats that fairground taste we all love. Try to get good quality stuff for the tastiest results.
- Powdered Sugar and Cornstarch: A light coating stops the marshmallows from sticking to each other and adds a touch of extra sweetness.
Making Your Cotton Candy Marshmallows
Get the Gelatin Ready
First, scatter the unflavored gelatin over 1/2 cup of water in a big bowl. Let it sit for about 5 minutes so it can swell up. Don't skip this part - it lets the gelatin drink up the water which gives you the right texture later on.
Prepare the Sugar Mix
In a pot, mix your granulated sugar, corn syrup, and water together. Heat it up over medium-high until it hits 240°F (115°C) on a candy thermometer. Getting this temperature just right is super important for perfect marshmallows.
Mix Everything Together
After your sugar mix reaches the right temp, slowly pour it into the bowl with the gelatin while stirring it constantly. Then beat the mixture with a mixer for 10-15 minutes until it gets really thick, shiny, and fluffy. This is the cool part where your liquid turns into that awesome marshmallow stuff.
Put In Taste and Look
When your mix looks right, add in the cotton candy flavoring. If you want them to look pretty too, drop in some food coloring that matches your cotton candy theme.
Let It Firm Up
Pour all your marshmallow goo into a greased 9x9-inch baking dish. Use a spatula to even out the top, then leave it alone at room temperature for at least 4 hours until it's completely firm.
Finish Them Off
After they're set, sprinkle them with a mix of powdered sugar and cornstarch. Then cut them into cubes or fun shapes using a knife or scissors.

I really love using the pink cotton candy flavor because it takes me back to going to fairs as a kid. My family can't get enough of these marshmallows, and now we make them for all our summer get-togethers.
Ways to Enjoy
Tasty Combinations
Enjoy these marshmallows with other fun treats like popcorn and chocolate, or float them on top of hot chocolate. They're also amazing on ice cream or blended into milkshakes.
Great for Gatherings
Make a cotton candy-themed snack table by putting the marshmallows in pretty containers. For a carnival feel, stick them on skewers like lollipops.
Grab and Go Treats
Put some marshmallow squares in small bags for easy party favors or snacks on the move.
Different Ways to Make Them
Special Diet Options
If you need a vegan version, use agar-agar instead of gelatin and make sure your cotton candy flavoring is plant-based.
Try New Flavors
Mix different cotton candy flavors together, like blue raspberry with vanilla, for something really special. A tiny bit of vanilla extract can also add more depth to the taste.
Play with Colors
Use natural food dyes for soft pastel colors or go all out with bright colors to make rainbow marshmallows.
Keeping Them Fresh
Seal Them Up
Keep your marshmallows fresh by storing them in containers that don't let air in. A glass jar or ziplock bag works great.
Keep Them Dry
Store them somewhere cool and dry so they don't get sticky from moisture.
Saving for Later
To keep them longer, freeze the marshmallows in a single layer on a baking sheet first, then put them in an airtight container. Let them warm up to room temperature before eating.
Cotton candy marshmallows aren't just tasty—they're like a trip down memory lane in each bite. Whether you're making them for friends, as gifts, or just because you want something sweet, these marshmallows add a bit of fun to your day. Try making them and let the cotton candy magic take you back to carefree, sweeter days.
