Cotton candy flavoring is usually sold in the baking aisle of grocery or craft stores. If you can’t find it locally, I recommend ordering some from LorAnn.
If your cakes are a bit flat, that’s most likely because you didn’t add enough baking powder. Also, be sure to check the expiration date on your baking powder! If it’s expired, it just won’t do the trick.
A dry cake can be caused by 2 things. You may have measured the ingredients incorrectly, or you might have overmixed the batter. It’s important to scoop and level your ingredients if you’re not using a scale, and it’s important to have a light hand when mixing the batter.
If your buttercream frosting is too thin, chill it for 10-20 minutes, then whip again. If it is still too thin, add powdered sugar, 1 tablespoon at a time, until it reaches the desired consistency. If your buttercream is too thick, add milk, 1 tablespoon at a time, until it reaches the desired consistency.
If your buttercream looks curdled, it is likely too cold. Place the buttercream in a heat-proof bowl set over a pot of simmering water until the edges begin to melt, then whip again until it comes together.
Recipe Tips and Tricks
- Your butter should be softened before mixing it. It will combine much easier and you will have an even texture throughout.
- Make sure the cake is fully cooled before frosting it. I like to bake the cake the day before and decorate it the next day so I know it’s fully cooled.
- This cake is perfect for bridal and baby showers too!
This candy cotton cake is so fun to both make and serve. You’ll be sure to impress with this, and make someone’s day super special!

Cotton Candy Cake Recipe
Ingredients
For the Cake
- 4 cups cake flour 480 grams, see note
- 1 tablespoon baking powder 12 grams
- 1¼ teaspoons kosher salt 4 grams
- 1 teaspoon baking soda 6 grams
- 1 cup unsalted butter 226 grams, room temperature (2 sticks)
- 3 cups granulated sugar 600 grams
- 5 large eggs 250 grams, room temperature
- 1¾ cups milk 398 grams, room temperature
- 1½ teaspoons cotton candy flavoring 8 grams (2 drams LorAnn)
- Blue and pink food coloring optional
For the Buttercream
- 2 cups unsalted butter 452 grams, room temperature (4 sticks)
- 7 cups powdered sugar 791 grams
- ⅛ teaspoon kosher salt
- ¾ teaspoon cotton candy flavoring 4 grams (1 dram LorAnn)
- Pink and blue food coloring optional
Equipment
- Kitchen Scale (optional)
- Piping Tip Set (optional)
Instructions
- Preheat oven to 350°F. Line 3 8-inch cake pans with parchment paper and spray them with nonstick spray. Set aside.
- In a large mixing bowl, combine the flour, baking powder, salt, and baking soda. Set aside.4 cups cake flour, 1 tablespoon baking powder, 1¼ teaspoons kosher salt, 1 teaspoon baking soda
- In the bowl of a stand mixer fitted with a paddle or whisk attachment, beat the butter and sugar together on medium-high for about 1 minute. Add in the eggs, milk, and cotton candy flavoring. Beat on high for another 1 minute. Add in the flour mixture and stir just until the flour has been incorporated. Divide evenly into 2 smaller bowls and color with blue and pink food coloring if desired.1 cup unsalted butter, 3 cups granulated sugar, 5 large eggs, 1¾ cups milk, 1½ teaspoons cotton candy flavoring, Blue and pink food coloring
- Alternately spoon blue and pink batter into the cake pans and gently swirl them together. Don’t swirl too much as the batter will turn purple and bake into a brown color. Place into the oven to bake for 20-23 minutes, or until a toothpick inserted comes out clean or with moist crumbs. Once baked, remove from the oven, place onto a cooling rack, and let cool to room temperature.
- While the cakes are cooling, make the buttercream. In the bowl of a stand mixer fitted with the paddle attachment, beat the butter, powdered sugar, salt, and cotton candy flavoring together. Beat first on low for about 2 minutes, or until the powdered sugar is almost completely incorporated, to avoid it from flying out of the bowl. Increase speed to high and let it whip for 4 minutes to create a smooth buttercream.2 cups unsalted butter, 7 cups powdered sugar, ⅛ teaspoon kosher salt, ¾ teaspoon cotton candy flavoring
- Separate the frosting evenly into 3 bowls. Color 1 bowl pink, 1 bowl blue, and leave the last bowl white.Pink and blue food coloring
- Once the cakes are cooled, place 1 layer onto a cake stand or plate. Top with about ¼ cup of buttercream and spread to the edges. Place a second layer of cake on top and frost. Place the last layer of cake on top. Frost the top and sides of the cake with buttercream. Alternate between white, blue, and pink frosting for a cotton candy, rainbow effect.
- For neat multi-colored frosting swirls, alternately spread some pink and blue buttercream onto the sides of a piping bag fitted with your choice of tip. Once you are happy with the mix of colors, fill the remainder of the bag with white buttercream. Pipe in a clock formating, piping 1 swirl each at 12:00, 6:00, 3:00, and 9:00. Continue in that fashion around the perimeter of the cake.
- If desired, top with clouds or pieces of cotton candy.
- Once the cake is frosted, slice and serve!
Notes
- Cake Flour: If you don’t have cake flour, you can make your own by measuring 1 cup of all-purpose flour, removing 2 tablespoons from the cup, and adding 2 tablespoons of cornstarch. Whisk together and sift well before using.
- Your butter should be softened before mixing it. It will combine much easier and you will have an even texture throughout.
- Make sure the cake is fully cooled before frosting it. I like to bake the cake the day before and decorate it the next day so I know it’s fully cooled.
- This cake is perfect for bridal and baby showers too!
I really enjoyed your article. Congrats on the content.
Thanks so much, Emanuel!
I am a baker, use to work professionally baking cakes. This recipe didn’t seem right to me but I went ahead & made it. After all you have a website & pictures of the cake.
The blue turned out green because of the yellow from the eggs. No way did it cook in the 30 minutes the recipe said. It took more like 35 minutes. When I put the eggs & milk in the butter immediately got cold & chunky. Overall it’s not a good cake recipe. Would not recommend it.
The batter was good with the taste of cotton candy from the oil you recommended.
Hi Debbi, I’m sorry this recipe didn’t work out for you! I’d love to help you troubleshoot.
I’m surprised that the blue came out green! I haven’t had that happen before. Did you use gel or liquid? The gel is usually much stronger in color!
As for the bake time, all ovens are different, so the bake time can vary! I recommend getting an oven thermometer to be sure that your oven is at the right temperature.
Were your eggs and milk also at room temperature? Cold milk and eggs can cause the butter to clump, so make sure that all of your eggs and dairy products are at room temperature!
