Whipped Cotton Candy Cake Recipe for Celebratory Parties

I can’t believe the comments here— I followed the exact directions and my cake came out perfectly! I used gel food coloring.

–

For the Cake

• 4 cups cake flour
• 1 tablespoon baking powder
• 1¼ teaspoons kosher salt
• 1 teaspoon baking soda
• 1 cup unsalted butter room temperature (2 sticks)
• 3 cups granulated sugar
• 5 large eggs room temperature
• 1¾ cups milk room temperature*
• 1½ teaspoons cotton candy flavoring
• Blue and pink food coloring optional

For the Buttercream

• 2 cups unsalted butter room temperature (4 sticks)
• 7 cups powdered sugar
• ⅛ teaspoon kosher salt
• ¾ teaspoon cotton candy flavoring
• Pink and blue food coloring optional

Bake the Cakes:

• Preheat oven to 350°F. Line three 8-inch cake pans with parchment and spray with nonstick spray. Set aside.
• Whisk together flour, baking powder, salt, and baking soda in a large bowl. Set aside.
  
• In a stand mixer fitted with the paddle or whisk, beat butter and sugar on medium-high about 1 minute until combined and slightly fluffy.
  
• Add eggs, milk, and cotton candy flavoring. Beat on high for 1 minute to combine.
  
• Fold in the flour mixture until just incorporated. Divide batter into two bowls and tint one blue and one pink if desired.
  
• Alternate spoonfuls of blue and pink batter into the pans and gently swirl. Take care not to over-swirl or the colors will mix and darken. Bake 20–23 minutes, or until a toothpick comes out clean or with moist crumbs. Cool completely on a rack.
  

Make the Buttercream:

• While the cakes cool, prepare the frosting. In a stand mixer with the paddle attachment, combine butter, powdered sugar, salt, and cotton candy flavoring. Start on low for about 2 minutes so the powdered sugar doesn’t puff out, then increase to high and whip 4 minutes until smooth and fluffy.
  
• Divide the frosting into three bowls. Tint one pink, one blue, and leave one white for a multi-colored buttercream.
  

Decorate the Cake:

• Place one cooled cake layer on a stand and spread about ¼ cup buttercream to the edges.
• Top with the second layer, add more buttercream, then place the final layer on top.
• Frost the top and sides, alternating white, blue, and pink to create a cotton candy effect.
• For neat multi-colored swirls, place small amounts of blue and pink into a piping bag, add white, then pipe swirls around the cake in a clock pattern (12:00, 3:00, 6:00, 9:00) and continue until complete.
• If desired, finish with small clouds or pieces of cotton candy just before serving. Slice and enjoy.

**If you can’t find cotton candy flavoring locally, it’s commonly available from specialty flavor suppliers.

***Pink and blue food coloring make both the cake and frosting extra vibrant, but they’re optional.

Tips:

• If you prefer a shortcut, use two boxes of white or yellow cake mix in place of the homemade cake ingredients (instructions below).
• Always make sure the cakes are fully cooled before frosting, or the buttercream can melt.
• Bake layers a day ahead and assemble the next day for easier decorating.
• Check the expiration date on baking powder and baking soda to ensure proper rise.
• Measure dry ingredients using the spoon-and-level method or a kitchen scale for consistency.
• Use room-temperature dairy ingredients to avoid a lumpy batter.
• If topping with cotton candy, add it right before serving to prevent it from dissolving in the frosting.

Storage: Store the cake in an airtight container at room temperature up to 2 days or refrigerate up to 4 days.
