Fluffy carnival-inspired marshmallows bring fairground magic straight to your home kitchen. These airy, cloud-like treats mix the fun flavor of spun sugar with homemade marshmallow softness, making something truly unique. Their soft pastel shades and sweet smell will take you back to fun-filled fair days with just one taste.
When I first whipped these up for my nephew's party, kids couldn't believe their eyes when they spotted the baby blue and pink treats on the sweets table. The grown-ups couldn't help grabbing some too, and they vanished quicker than any store candy. There's something totally magical about soft, bouncy texture mixed with carnival-sweet taste that makes everyone feel like a kid again.
Delightful Ingredient Breakdown
- Unflavored gelatin: Gives that perfect bounce; make sure it's fully soaked for smooth setting without any grainy bits
- Granulated sugar: Forms the main sweetness and framework; grab cane sugar for top-notch results
- Light corn syrup: Stops sugar crystals forming and helps create that dreamy, soft feel
- Cotton candy flavoring: The key item that turns plain marshmallows into fair treats; you can find it at cake shops or websites
- Food coloring: The thick gel type works way better for bright colors without making your mix too wet
- Powdered sugar: Combined with cornstarch, it makes the perfect dust coat to keep things from getting sticky
When picking cotton candy flavor, I go for LorAnn or Amoretti brands because their strong flavor won't water down your marshmallow mix. Spending a bit more on good flavoring really pays off when you want that real spun sugar taste.
Set Up Your Workspace
Get a 9×9-inch baking dish ready with parchment paper and sprinkle lots of the sugar-cornstarch mix all over. This stops everything from sticking and helps you pull out your treats easily once they've set.
Soften The Gelatin
Put unflavored gelatin on top of cold water in your stand mixer bowl. Let it sit without touching for a full 5 minutes until it looks like a thick, see-through jelly.
Make The Hot Syrup
Mix your regular sugar, corn syrup, salt, and water in a sturdy pot. Warm it slowly till sugar melts away, then let it bubble hard until it hits exactly 240°F on your candy thermometer.

Beat Until Fluffy
While your mixer runs slowly, carefully pour the hot sugar mix into the soft gelatin. Once it's all in, turn speed to high and whip for 12-15 minutes until everything gets super thick, shiny, and grows three times bigger.
Mix In The Magic
During the last minute of mixing, drop in your carnival flavoring and food colors. For extra fun, split the fluffy stuff and make half pink, half blue before putting them in layers in your pan.
Rest And Cut
Dump the puffy mixture into your ready pan, flatten the top, and sprinkle more coating mix over it. Let it sit undisturbed at room temp for at least 4 hours before cutting into cubes.
My kid and I make these treats every summer as a nod to our carnival visits. She loves watching the stuff grow huge during mixing. To her it's like kitchen wizardry, and truthfully, I still feel amazed even after making tons of batches.
Festive Serving Suggestions
These pastel goodies taste amazing floating in hot cocoa for a playful twist on an old favorite. For get-togethers, build a fairground sweets station with the marshmallows next to real spun sugar, puffy cupcakes, and bright cookies. Stick them on wooden skewers with fresh berries and brownie chunks for grab-and-go sweet kebabs that everyone will go crazy for.
Taste Adventures
Change things up by trying new flavor and color combos. Maybe make blue raspberry fairground marshmallows with a bit of lemon for tang. If you love chocolate, toss tiny chips into the mix right before pouring. You can even create stripes by adding different colored batches to your pan in layers for treats that look fancy but taste way better than anything from a store.

Storage Tips
Keep your finished treats in sealed containers with baking paper between each layer so they don't stick together. They'll stay good at room temp for about two weeks if kept somewhere cool and dry. For gifts, wrap them in clear bags tied with bright ribbons or put them in pretty tins lined with paper. If your marshmallows start sticking to each other after sitting awhile, just dust them with more of your sugar-cornstarch mix before serving.
I've found through countless tries that taking your time leads to perfect marshmallows. The full beating time might seem too long, but those extra minutes turn ordinary fluff into something amazing. My grandma always told me good stuff takes time, and these spun-sugar puffs of sweetness prove she was right with every soft, tasty bite.
