What You Need to Make Cotton Candy Cake
Let’s start with the ingredients and tools.
For the Cake:
- All-purpose flour
- Sugar
- Eggs
- Butter
- Baking powder
- Milk
- Cotton candy flavoring (you can find this online or in baking stores)
- Pink and blue food coloring (gel colors work best)
For the Frosting:
- Butter
- Powdered sugar
- Cotton candy flavoring
- Pink and blue food coloring
Tools:
- 2 or 3 round cake pans
- Parchment paper
- Mixing bowls
- Electric mixer
- Piping bags (optional for decoration)
- Cake stand or plate
How to Make the Cake Step by Step
- Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease your cake pans with butter or spray, and line the bottoms with parchment paper.
- Make the Batter
In a large bowl, beat butter and sugar together until fluffy. Add the eggs one at a time, mixing well. In another bowl, mix the flour and baking powder. Slowly add the dry mix to the butter mixture, alternating with the milk. Now add a few drops of cotton candy flavoring and mix again.
Split the batter into two bowls. Add pink food coloring to one and blue to the other. Stir until the colors are even. - Bake the Cake
Pour the batter into the cake pans. Bake for about 25–30 minutes, or until a toothpick in the center comes out clean. Let the cakes cool completely.
- Make the Frosting
Beat softened butter until smooth. Slowly add powdered sugar and keep mixing. Add cotton candy flavoring and stir. Divide the frosting into two bowls and color them pink and blue.
- Assemble and Decorate
Place one cake layer on your stand or plate. Spread frosting on top, then add the next layer. Frost the whole cake with the pink and blue frosting. You can mix the colors for a fun swirl effect. Decorate with extra frosting swirls, sprinkles, or real cotton candy on top. Add the cotton candy right before serving so it doesn’t melt.
Easy Tips for a Great Cake
- Use good cotton candy flavoring for the best taste.
- Gel food coloring gives bright colors without making the batter too thin.
- Only add real cotton candy on top just before serving — it melts fast!
- You can make the cake layers a day ahead and frost them the next day.
- Store the cake in a container at room temperature for up to 3 days (without cotton candy on top).
Frequently Asked Questions
This cake stays fresh for about 3 days at room temperature in an airtight container. Keep it away from heat and moisture. Don’t store it with cotton candy on top — it will melt.

Yes! It looks fun and adds a party feel. Just make sure to put it on right before serving, because it melts when it touches frosting or air for too long.
