Ingredients

2 1/2 cups (265g) sifted cake flour
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 1/2 cups (300g) granulated sugar
1/2 cup (113g) unsalted butter, room temperature
4 large egg whites, room temperature
1/2 cup (120ml) vegetable oil
1 tablespoon Amoretti Natural Cotton Candy Artisan Flavor
1 1/4 cups (300ml) full-fat buttermilk, room temperature
1 drop blue food coloring (optional)
1 drop pink food coloring (optional)
2 cups (452g) unsalted butter, room temperature (for buttercream)
7 cups (840g) powdered sugar
1 teaspoon Amoretti Natural Cotton Candy Artisan Flavor (for buttercream)
4 tablespoons whole milk, room temperature
1/4 teaspoon salt
1 small drop blue food color gel
1 small drop purple food color gel
1 cup cotton candy (for topping)

Instructions

Step 1: Preheat the oven to 350°F (177°C). Prepare three 6-inch or two 8-inch cake pans by spraying them with baking spray and lining the bottoms with parchment paper circles.
Step 2: In a medium bowl, whisk together the sifted cake flour, baking powder, baking soda, and salt. Set aside.
Step 3: Using a stand mixer fitted with the paddle attachment, beat the butter on high speed until creamy, about 2 minutes. Add the granulated sugar and beat on medium-high until light and fluffy, scraping down the bowl as needed.
Step 4: Reduce mixer speed to low. Add egg whites one at a time, mixing until just combined. Scrape the bowl, then add vegetable oil and cotton candy flavor. Beat on high for 1 minute.
Step 5: Turn off the mixer. Add the dry ingredients and mix on low speed until just combined. Gradually pour in the buttermilk and mix until the batter is uniform and slightly thin.
Step 6: Divide the batter evenly into two bowls. Add pink food coloring to one bowl and blue to the other, stirring until colors are uniform.
Step 7: Alternately layer pink and blue batter into the prepared pans using a 1/2 cup measuring cup. Bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean.
Step 8: Let the cakes cool in the pans for 5 minutes, then transfer to a wire rack to cool completely.
Step 9: To prepare the buttercream, beat the 2 cups of unsalted butter on medium-high speed for about 7 minutes until light and fluffy. Gradually add powdered sugar at low speed, scraping down the bowl as needed.
Step 10: Add milk and salt, mix until smooth. Reserve 1 cup of buttercream for pastel colors.
Step 11: Mix 1 teaspoon cotton candy flavor into the remaining buttercream. Divide the reserved buttercream into two bowls and tint with blue and purple food color gels as desired.
Step 12: Level the cooled cake layers. Stack them with about 3/4 cup of buttercream between each layer. Apply a crumb coat and refrigerate for 30 minutes.
Step 13: Frost the cake using the pastel and pink buttercream for a watercolor effect. Create decorative swirls with a piping bag if desired.
Step 14: Just before serving, top the cake with a generous amount of cotton candy. Serve promptly, as cotton candy will begin to shrink after about one hour.

Tips & Variations

For best results, use room temperature ingredients to ensure even mixing and a tender crumb.
Adjust the food coloring amount to achieve your preferred intensity of pastel shades.
Substitute Amoretti Natural Cotton Candy Artisan Flavor with any cotton candy flavoring available or omit for a more subtle taste.
If you don’t have buttermilk, mix 1 1/4 cups milk with 1 tablespoon lemon juice or white vinegar and let it sit for 5 minutes.
Try adding edible glitter or sprinkles for extra festivity on top of the frosting.

Storage

Store the frosted cake covered in the refrigerator for up to 3 days. Because of the delicate cotton candy topping, add it only just before serving to maintain its fluffiness. Leftover cake layers can be wrapped tightly and frozen for up to 1 month; thaw overnight in the refrigerator before frosting and serving.

How to Serve

Each layer is separated by a thin, even layer of smooth white cream. The outside cake surface is covered in swirled pastel blue, pink, and purple frosting creating a soft, cloud-like texture. The top edge of the cake is decorated with high, ruffled swirls of the same pastel colors, sprinkled lightly with tiny pink sugar bits. The cake sits on a clean white plate on a white marbled surface with some crumbs scattered around. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make this cake without food coloring?

Yes, the cake will still taste delicious without food coloring, but it will lack the signature cotton candy pastel look. You can leave the batter natural or add other subtle natural colorings if preferred.

What is the best way to serve cotton candy cake?

Serve the cake at room temperature for the best flavor and texture. Add the cotton candy topping right before serving as it will dissolve or shrink if left out too long.
