For the Cake:

  • 2 1/2 cups all-purpose flour
  • 2 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1 cup unsalted butter, softened
  • 1 3/4 cups granulated sugar
  • 5 large egg whites
  • 2 tsp vanilla extract
  • 1 cup milk
  • 1 cup cotton candy, chopped (plus more for garnish)
  • Pink food coloring
  • Blue food coloring

For the Frosting:

  • 4 cups powdered sugar
  • 1/2 cup unsalted butter (room temperature)
  • 2–3 tbsp milk (as needed for consistency)

Step-by-Step Instructions: How to Make Cotton Candy Cake

Creating this cake is surprisingly simple, even for beginner bakers. Follow these easy steps to bake and decorate your cotton candy masterpiece.

1. Prep Your Pans and Preheat the Oven

  • Preheat your oven to 350°F (175°C).
  • Grease and flour two 9-inch round cake pans, or line them with parchment paper for easy release.

2. Combine Dry Ingredients

In a medium mixing bowl, whisk together:

  • Flour
  • Baking powder
  • Salt

Set this bowl aside — it’s your dry base for the batter.

3. Cream Butter and Sugar

In a large bowl, beat:

  • 1 cup softened unsalted butter
  • 1 3/4 cups granulated sugar

…until the mixture is light and fluffy — this usually takes about 3–5 minutes on medium-high speed. This step is crucial for a soft cake texture.

4. Add Egg Whites and Vanilla

  • Add egg whites one at a time, beating well after each addition.
  • Stir in 2 tsp of vanilla extract.

This creates a fluffy, white base — perfect for marbling with color later.

5. Alternate Wet and Dry Ingredients

Alternate adding:

  • The dry flour mixture
  • 1 cup of milk

Begin and end with the flour mixture. Mix just until everything is combined — don’t overmix.

6. Fold in Cotton Candy

Now, gently fold in 1 cup of chopped cotton candy. The goal is to distribute it evenly without melting it too much. This gives the cake a sweet, mysterious texture that surprises with each bite.

7. Tint and Swirl the Batter

Divide the batter into two bowls. Tint one with pink food coloring and the other with blue.

In your prepared cake pans, alternate spoonfuls of pink and blue batter, then swirl lightly with a toothpick or knife for a marbled effect.

8. Bake and Cool

  • Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.

9. Make the Frosting

While the cakes cool, beat:

  • 1/2 cup unsalted butter until creamy
  • Gradually add 4 cups powdered sugar
  • Add 2–3 tbsp milk, one tablespoon at a time, until frosting is smooth and spreadable.

You’re aiming for a thick, fluffy frosting that holds its shape.

10. Assemble and Decorate

  • Once cakes are fully cooled, frost the top of one layer, then place the second layer on top.
  • Frost the entire cake evenly.
  • Just before serving, garnish with extra cotton candy for a magical, cloud-like finish.

Tips for Success

Want your cotton candy cake to turn out picture-perfect every time? Here are some expert tips:

✅ Use Fresh Cotton Candy

Cotton candy begins to melt when exposed to moisture, so only fold it into the batter right before baking, and add garnish just before serving.

✅ Don’t Overmix the Batter

Mix just until the ingredients are incorporated to keep your cake light and airy.

✅ Chill Before Slicing

If you have time, chill the cake for 30 minutes before slicing. This makes for cleaner cuts and more defined swirls.

✅ Add a Flavor Boost

For extra cotton candy flavor, you can use cotton candy flavoring (available online) in place of or in addition to the vanilla extract.

Creative Twists and Variations

Want to put your own spin on this recipe? Here are a few fun ideas:

  • Rainbow Swirl Cake: Add more colors like purple and teal for a full unicorn effect.
  • Filled Cake: Spread a layer of cotton candy-flavored buttercream or marshmallow fluff between the cake layers.
  • Mini Cakes: Use the same batter in cupcake tins or mini cake molds for individual servings.
  • Drip Effect: Add a pink or blue white chocolate drip for that trendy cake shop look.

When to Serve Cotton Candy Cake

This cake is a guaranteed showstopper at:

  • Birthday parties (especially for kids and tweens)
  • Carnival or fair-themed events
  • Baby showers (use pink or blue to hint at gender)
  • Bridal showers
  • Sleepovers or movie nights

Or, simply whip it up on a weekend when you’re craving something magical and different.

How to Store Your Cotton Candy Cake

Keep your cotton candy cake looking and tasting fresh with these storage tips:

  • Without garnish: Store frosted cake in an airtight container at room temperature for up to 2 days.
  • With cotton candy garnish: Always add the cotton candy right before serving, as it will dissolve if left on the frosting too long.
  • To freeze: Wrap unfrosted cake layers tightly in plastic wrap and freeze for up to 2 months. Thaw before frosting.
