Step-by-Step Instructions
1. Prepare the Cake Layers
Preheat your oven to 350°F (175°C). Grease and line three 6-inch pans with parchment paper.
In a bowl, whisk together the flour, baking powder, and salt.
In a separate large bowl, beat the butter and sugar until pale and fluffy. Add eggs one at a time, mixing thoroughly after each addition. Stir in the cotton candy flavoring.
Alternate adding the dry ingredients and milk, starting and ending with the dry mixture. Mix until smooth—do not overmix.
2. Color the Batter
Divide the batter evenly into three bowls. Add different gel colors to each and gently mix until evenly tinted.
Pour each colored batter into prepared pans.
3. Bake to Perfection
Bake for about 35 minutes, or until a toothpick inserted in the center comes out clean.
Let cakes cool completely before removing from pans.
4. Make the Buttercream
Place egg whites and sugar in a heatproof bowl over simmering water. Whisk continuously until sugar dissolves and mixture is warm.
Transfer to a mixer and whip until stiff, glossy peaks form and the mixture cools.
Gradually add butter, mixing until smooth and creamy. Add cotton candy flavoring and blend.
5. Assemble the Cake
Level the cooled layers.
Place the first layer on a serving plate and spread buttercream evenly. Repeat with remaining layers.
Apply a thin crumb coat and chill briefly.
6. Decorate Like a Pro
Color remaining buttercream in pastel shades and apply in patches. Smooth gently for a blended watercolor effect.
Top with cotton candy just before serving for maximum visual impact.
