→ Decoration

# Directions:
01 - Preheat the oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
03 - In a large bowl, beat the softened butter and granulated sugar with an electric mixer until light and fluffy, about 3–4 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in the cotton candy flavoring and vanilla extract until evenly distributed.
05 - With the mixer on low speed, add the flour mixture in three parts, alternating with the milk, beginning and ending with the flour. Mix until just combined.
06 - Divide the batter evenly into two bowls. Tint one portion pink and the other blue with food coloring. Drop spoonfuls of each color alternately into the prepared pans for a marbled effect, then swirl gently with a skewer or knife.
07 - Bake for 25–28 minutes, or until a toothpick inserted in the center comes out clean. Cool the cakes in the pans for 10 minutes, then turn out onto a wire rack to cool completely.
08 - Beat the butter until creamy. Gradually add the powdered sugar on low speed, then mix in the cotton candy flavoring and milk until smooth and fluffy. Divide the buttercream and tint pink and blue as desired.
09 - Once the cake layers are completely cool, stack and frost with the buttercream. Swirl the pink and blue frosting together for a cotton candy effect.
10 - Just before serving, arrange fluffy pieces of fresh cotton candy on top of the cake. Serve immediately.
# Expert Tips:
01 -
- The marbled pink and blue batter looks like a sunset inside every slice, and guests always gasp when they see it.
- Cotton candy flavoring gives the cake a sweet, whimsical taste that feels like childhood without being overwhelmingly artificial.
- The buttercream is velvety and pipes beautifully, so even rookie decorators can pull off a showstopper.
02 -
- Fresh cotton candy begins dissolving the instant it touches moisture, so never place it on the cake until you are literally carrying the cake to the table.
- Overmixing the batter after adding flour is the fastest path to a tough, rubbery cake. Stop the mixer when you still see a few faint streaks of flour and finish by hand.
03 -
- Gel food coloring gives you vivid pastels without watering down your batter or buttercream, and a little goes a very long way.
- Chill your frosted cake in the fridge for 20 minutes before adding the cotton candy garnish because a cold surface slows the melting process and buys you precious extra minutes.
