For the Cotton Candy Cake Layers:

  • 1 ½ cups (180g) all-purpose flour

  • 1 cup (200g) granulated sugar
    • Reduce to ¾ cup if using cotton candy syrup instead of extract
  • ½ cup (113g) unsalted butter, room temperature
    • Vegan option: Use plant-based butter sticks
  • 2 large eggs, separated
    • Egg-free: 2 flax eggs (2 tbsp ground flaxseed + 5 tbsp water)
  • ½ cup (120ml) whole milk
    • Dairy-free: Almond or oat milk work well
  • 1 ½ tsp cotton candy extract(or ¼ cup reduced cotton candy syrup)
    • Find this near vanilla extract in baking aisles
  • 1 tsp vanilla extract (enhances flavor depth)
  • Gel food coloring (pink, blue, purple)
    • Why gel? More vibrant colors without thinning batter
Precisely two eggs with cotton candy cake ingredients: pink bowl of flour, blue sugar bowl, butter cubes, milk bottle, extracts, and pink/blue/purple food coloring tubes arranged on marble surface with sprinkles

For the Cotton Candy Buttercream:

  • 1 cup (226g) unsalted butter, softened
  • 3 cups (360g) powdered sugar
  • 2 tbsp heavy cream (or milk for lighter texture)

📝 Step-by-Step Instructions

STEP1 : Prep Work

  • Preheat oven to 350°F (175°C)
  • Prepare pans:
    • Grease two 6-inch round pans (or one 9-inch)
    • Line bottoms with parchment paper
    • Lightly dust sides with flour

STEP2 : Mix Dry Ingredients

  • In a medium bowl, whisk together:
    • 1 ½ cups (180g) all-purpose flour
    • 1 ½ tsp baking powder
    • ¼ tsp salt
  • Set aside

STEP3 : Cream Butter & Sugar

  • In a large bowl, beat until light and fluffy (~2-3 mins):
    • ½ cup (113g) room-temperature butter
    • 1 cup (200g) granulated sugar
  • Scrape bowl halfway

STEP4 : Add Wet Ingredients

  • Mix in one at a time:
    • 2 large egg yolks (reserve whites!)
    • 1 ½ tsp cotton candy extract
    • 1 tsp vanilla extract

STEP5 : Alternate Dry/Wet Mixes

  • Add ⅓ of dry ingredients, mix until just combined
  • Pour in ½ of milk (¼ cup), mix gently
  • Repeat, ending with dry ingredients
  • Do not overmix – small lumps are okay

STEP6 : Fold in Whipped Egg Whites 

  • In a clean bowl, beat until stiff peaks:
    • 2 reserved egg whites
    • ¼ tsp cream of tartar (stabilizer)
  • Gently fold into batter with rubber spatula

STEP7: Color & Pour Batter

  • Divide batter into 2-3 bowls
  • Tint with toothpick-dipped gel colors
  • Layer colors in pans or swirl gently
  • Fill pans ¾ full

STEP8: Bake & Cool

  • Bake 25-30 mins (6-inch) or 30-35 mins (9-inch)
  • Test doneness:
    • Toothpick comes out clean
    • Cake springs back when lightly pressed
  • Cool in pans 10 mins, then transfer to wire rack
  • Cool completely before frosting

Frosting & Assembly: Building Your Cotton Candy Masterpiece

1. Make the Cotton Candy Buttercream

  • Beat butter (1 cup/226g) until creamy and pale (~3 mins)
  • Gradually add powdered sugar (3 cups/360g) on low speed (to avoid clouds!)
  • Mix in:
    • 2 tbsp heavy cream (or milk for lighter texture)
    • 1 tsp cotton candy extract
    • Pinch of salt (cuts sweetness)
  • Tint frosting with gel colors to match cake layers

2. Prep Cake Layers

  • Level cakes if needed: Use a serrated knife to trim domed tops
  • Brush layers with simple syrup (optional):
    • Mix 2 tbsp water + 1 tbsp sugar, brush lightly for extra moisture

3. Assemble Layers

  • Anchor the base: Spread a dab of frosting on cake board to prevent sliding
  • First layer: Place on turntable, spread ½ cup frosting with offset spatula
  • Second layer: Add upside-down for a flat top
  • Crumb coat: Apply thin frosting layer, chill 15 mins (seals in crumbs!)

🔥 Troubleshooting:

  • “Frosting too soft?” Chill 10 mins before piping
  • “Crumbs in frosting?” Wipe spatula between strokes

4. Frost Smoothly

  • Final coat: Apply thick frosting, spin turntable while smoothing sides
  • Two-tone effect:
    1. Divide frosting into 2 bowls, tint each
    2. Alternate colors in piping bag for swirls

Storage & Make-Ahead Tips: Keeping Your Cotton Candy Cake Fresh

Ensure your masterpiece stays as magical as the day you made it with these essential storage solutions and time-saving prep tricks.

1. Short-Term Storage (0-24 Hours)

🔹 Frosted Cake:

  • Room Temp: Keep covered with a cake dome or inverted bowl for up to 1 day (ideal for parties!)
  • Fridge: Store in an airtight container if your kitchen is warm. Bring to room temp 1 hour before serving for best texture.

⚠️ Important Note:
Real cotton candy toppers will dissolve in humidity! Add them just before serving or use cotton candy-flavored decorations instead.

2. Long-Term Storage (Up to 1 Month)

🔹 Unfrosted Layers:

  • Freezer: Wrap each layer tightly in:
    1. Plastic wrap
    2. Aluminum foil
    3. Place in a ziplock bag (squeeze out air)
  • Thawing: Transfer to fridge overnight, then frost as usual

🔹 Frosted Cake:

  • Freezer: Flash-freeze uncovered for 1 hour until frosting is firm, then wrap as above
  • Thaw: Unwrap and refrigerate for 4+ hours to prevent condensation

3. Make-Ahead Timeline

🎂 For Stress-Free Parties:

WhenTask
3 Days BeforeBake & freeze layers
1 Day BeforeThaw layers, make frosting

4. Reviving Stale Cake

  • Steamer Method: Hold slices over simmering water for 3 seconds to refresh crumb
  • Microwave Trick: Dampen a paper towel, cover cake, and heat for 8 seconds

5. What NOT to Do

❌Don’t refrigerate unfrosted cakes uncovered (they’ll dry out)
❌Avoid freezing cakes with fresh fruit fillings (becomes mushy)
❌Never thaw frozen cake at room temp (causes soggy layers)
