Step-by-Step Instructions
- Decorate With Cotton Candy and Sprinkles:
- Ready to show off? Pop on clouds of cotton candy over the top and around the sides. Finish with sprinkles for extra fun. Decorate right before eating so the cotton candy stays fluffy.
- Assemble and Frost:
- Set down the first layer and scoop on some frosting. Stack the next layers on top, more frosting in between. Smother the outside in icing so it looks super smooth and covered.
- Whip the Frosting:
- Soften your butter and whip it in a big bowl. Toss in powdered sugar gradually—sift it as you go. Add heavy cream or milk as needed. Beat until you get a fluffy spread. Mix in vanilla and cotton candy flavor, color if you like.
- Cool the Cakes:
- Let baked layers chill for ten minutes in the pans before flipping onto a rack. Wait for them to be completely cool before you add icing or it’ll melt right off.
- Bake the Cakes:
- Spoon the tinted batters evenly into pans. Smooth the top and bake about 25–30 minutes—poke with a toothpick to check for crumbs. Filling each pan evenly gives nice layers.
- Color the Batter:
- Split batter into a couple bowls, one for each shade you want. Add your food coloring and gently stir to get those dreamy pastels.
- Alternate Adding Dry Ingredients and Milk:
- Add dry mix and milk to your bowl, a little at a time. Start and finish with flour mix. Stir gently—overmixing makes things dense instead of soft.
- Incorporate the Eggs and Extracts:
- Crack in the eggs one at a time, mixing while you go. Once they’re all mixed in, splash in your vanilla and cotton candy extracts so flavor’s everywhere.
- Cream the Butter and Sugar:
- Beat soft butter and sugar together until the mix looks pale and fluffy—use an electric mixer for about two or three minutes. This makes your cake nice and tender.
- Whisk the Dry Ingredients:
- Combine flour, baking powder, and salt in a mixing bowl. Mixing now keeps things even and fluffy later with no clumps.
- Prepare the Cake Pans:
- Get your oven hot at 175°C. Grease three round pans (20 cm) and stick parchment on the bottom so nothing sticks later.

Swirling food coloring with my niece is my favorite. We always hope for swirls when we peek into the oven. Tasting icing with her while we decorate makes baking together so much fun every single time.
Keeping It Fresh
Seal your cake in an airtight container on the counter for a couple days so it keeps soft. Only stick cotton candy decorations on right before serving—otherwise they'll collapse into the frosting. For longer storage pop it in the fridge but let it warm up before eating so the layers stay pillowy.
Swaps and Switches
No cotton candy extract? Use almond or raspberry for a cool twist. Gel coloring is tops for bright even color, but regular liquid food coloring works if that’s all you’ve got. You can use non-dairy milk instead of whole milk, though the cake might be a little less rich.
How to Serve
This showstopper makes any event brighter, like birthdays, baby showers, or big tea parties. Put a puff of cotton candy on each slice for full carnival vibes. Team it up with some sparkling lemonade or berry punch to make your dessert table sparkle.

The Sweet Story Behind It
This treat comes straight from childhood memories of sticky fairground fingers and laughing with siblings. Pouring those pastel batters into pans reminds me of classic blue and pink clouds on carnival sticks. Whenever I cut into this cake, I think of carousel rides and that good old candy floss magic.
