Step-by-Step Instructions
- Prepare the Cake Pans:
- Preheat your oven to 175 degrees Celsius. Grease three 20 centimeter round cake pans and line each one with a round of parchment paper. This prevents sticking and helps your cake release cleanly.
- Whisk the Dry Ingredients:
- In a medium bowl thoroughly whisk together your flour baking powder and salt. Mixing these well now ensures your cake will rise evenly and have no clumps.
- Cream the Butter and Sugar:
- Using an electric mixer in a large bowl beat your softened butter with the granulated sugar. Mix for two to three minutes until the mixture is pale and fluffy the creaming step creates the foundation for a tender cake crumb.
- Incorporate the Eggs and Extracts:
- Add eggs one by one into the butter mixture mixing thoroughly after each addition. Once eggs are in mix in the vanilla and cotton candy extracts to evenly distribute the flavors.
- Alternate Adding Dry Ingredients and Milk:
- Gradually add the dry mix and whole milk to the butter mixture alternating between the two and beginning and ending with the dry mix. Stir gently after each addition to keep the batter smooth but not overworked this preserves tenderness.
- Color the Batter:
- Split the batter evenly into two or more bowls depending on how many colors you wish to create. Add desired food coloring to each bowl and gently mix to get vivid even tints.
- Bake the Cakes:
- Pour the colored batters into the prepared pans smoothing the tops with a spatula. Bake for twenty five to thirty minutes until a toothpick inserted into the center comes out clean. Evenly filling the pans ensures uniform layers.
- Cool the Cakes:
- Allow the cakes to cool for ten minutes still in their pans before inverting onto a wire rack. Let them cool completely before decorating to keep the frosting from melting.
- Whip the Frosting:
- In a large bowl beat the softened butter until creamy. Gradually add the powdered sugar sifting as you go alternating with heavy cream or milk. Beat until the frosting is light and fluffy then mix in both extracts and add more coloring if you like.
- Assemble and Frost:
- Place the first cake layer on a serving plate and spread a thin even layer of frosting on top. Repeat with remaining cake layers then coat the entire outside in a generous blanket of frosting for a smooth finish.
- Decorate With Cotton Candy and Sprinkles:
- When ready to serve top and coat the cake sides with pieces of cotton candy and add sprinkles if desired. Add the cotton candy at the last moment to keep it fluffy and prevent it from wilting.

My favorite part is swirling the food coloring into the batter with my niece and waiting to see what kind of marbled effect comes out of the oven. Sneaking tastes of the frosting together while decorating made the kitchen a very sweet place.
Storage Tips
Keep the cake in an airtight container at room temperature for up to two days to maintain freshness. Only add cotton candy decorations right before serving or they will melt into the icing. If you need to store it longer refrigerate but allow the cake to come to room temperature before eating so the layers stay soft.
Ingredient Substitutions
If cotton candy extract is hard to find a splash of almond or raspberry extract gives a delicious twist. Gel food colorings work best for vibrant layers without thinning the batter but regular liquid coloring will work in a pinch. Non dairy milk can substitute for whole milk though the crumb will be slightly less rich.
Serving Suggestions
This cake makes a magical birthday centerpiece but is equally delightful for baby showers tea parties or any event that calls for a pop of color. Serve each slice with a small tuft of fresh cotton candy on top for the full carnival effect. Pair with sparkling lemonade or berry punch for a festive treat platter.
