Super fluffy marshmallows packed with cotton candy flavor will send you right back to summers spent at the fair. Their pretty blue and pink swirls make every bite feel extra special and sweet. Once you try these soft pillowy treats, you'll see why they're gone in no time—nobody can resist the nostalgia mixed with that irresistible cotton candy taste.
I gave these a shot for my niece's birthday bash last summer, a little nervous since I'd never made marshmallows myself. Turns out, the kids kept coming back for more—big smiles all around! Even the adults couldn't stay away, sharing stories about fairground nights and sneaking extra bites just like the kids. Looks like I've found my new specialty.
Dreamy Marshmallow Basics
- Cornstarch: Keeps them from sticking and balances the softness; mix with powdered sugar for best texture
- Powdered sugar: Makes them even sweeter and coats them perfectly without lumps—give it a quick sift first
- Food coloring: Puts the wow factor in; gel gives you vibrant color with no mess
- Cotton candy flavoring: Brings in that classic fair vibe—grab oil-based if you can for extra oomph and no extra water
- Corn syrup: Stops sugar from getting gritty and makes it suuuper smooth—pick the light kind to let flavors shine through
- Granulated sugar: Sweetness you can’t skip; pure cane keeps it clean-tasting with no weird molasses flavor
- Unflavored gelatin: Gives your marshmallows their signature squishy bounce—bloom it properly and don’t use old packets for best results
Chill Prep Flow
Let’s get that gelatin going: pour cold water into your mixing bowl, sprinkle gelatin all around, then walk away for five minutes while it soaks in and turns jelly-like.
Now make the sugar mix: stir together your sugar, corn syrup, and some water in a sturdy pan until clear, then let it bubble—don’t touch it after it’s boiling.
Watch the temp! Pop a candy thermometer on the side and wait for it to hit 240°F, also called soft-ball stage. This step is super important for the right texture.
Mix it up: With the mixer going on medium, pour hot syrup right along the side of your bowl into the gelatin—aim for the edge, not the whisk, to skip splashing.
Pump up the volume: Crank the mixer to high and see it turn from see-through to a bright white fluff that gets huge fast.
Mix in flavors: When it holds soft peaks and isn't too hot to touch, squirt in your cotton candy flavor and food coloring, then watch the swirls pop!
Get it set: Grease your pan well, then spread your fluffy mix with an oiled spatula (trust me, it’s sticky).
Chop it up: Once it’s set nice and firm, dust a board with the sugar-starch mix, flip it out, and slice it using a knife dipped in hot water each time.

Found out the hard way what humidity can do—my batch wouldn't set on a rainy day. My grandma told me to toss in one more spoonful of gelatin when the weather is wet. Total life-saver! Now anytime it looks stormy, I use her little trick, and my marshmallows always turn out just right with that unmistakable cotton candy happiness in each chew.
Yummy Serving Mixups
Pair these marshmallows with rich hot chocolate and watch them melt into a sweet cotton candy cloud on top. When it’s hot outside, slap one between graham crackers and a thin layer of white chocolate—you get the ultimate carnival s’more. They also look awesome piled onto a snack board with vanilla wafers and fresh strawberries for a party tray everyone digs into.
Fun Remix Ideas
Change up the flavor by using blue raspberry cotton candy oil instead of the regular pink kind. Sweet but tangy! Try stacking different colored batches one on top of another when pouring into your pan for a wild striped effect when you slice them up. If you want to feel fancy, a tiny bit of champagne extract with your cotton candy flavor makes these perfect for dessert wine pairings or floating in party cocktails.
Long-Lasting Goodness
Keep these marshmallows soft by layering parchment between them in a sealed container hidden away from heat and sunlight. They’ll stay perfect for up to two weeks if you keep things dry. Giving them as gifts? Pop one into a little baggie with a ribbon and toss on a bit more powdered sugar to stop them sticking. Got a slightly stale batch? Lightly spray with water and dust with fresh powdered sugar—they’ll perk right up.
After making hundreds of marshmallows, these cotton candy ones are a crowd favorite every single time. People light up when they realize they're getting that fairground taste instead of boring vanilla. Sharing these at family events means I always go home with empty trays and lots of happy memories. Sometimes the treats that bring the most joy are also the easiest to share with everyone you love.

Recipe FAQs
- → What if I don’t own a stand mixer?
- You can absolutely use a hand mixer, but it’ll take some effort! Plan to whip it for about 10-12 minutes to get that thick, fluffy texture. A stand mixer just keeps things simpler.
- → Where can I buy cotton candy flavoring?
- Check out baking specialty shops, craft stores like Michael’s, or browse online platforms like Amazon. If you're in a pinch, vanilla extract can work instead, though the flavor will differ.
- → Can I switch up the colors?
- Of course! While pink and blue are the classic choices, feel free to go with purple, yellow, or even try mixing shades for a fun swirl effect.
- → How long can I store these marshmallows?
- Keep them in a sealed container at room temperature, and they’ll stay good for around a week. Don’t refrigerate, as the texture can become sticky and unpleasant.
- → Can I use these for s’mores?
- Absolutely! They toast wonderfully over a flame. The cotton candy flavor adds a cool twist that kids (and adults) will think is awesome.
- → Are these suitable for vegetarians?
- They’re not vegetarian-friendly because gelatin, a key ingredient, is derived from animals. You could try using agar-agar to make them plant-based, though you might need to tweak the method.
