Step-by-Step Instructions

Prepare the Cake Batter:

Preheat your oven thoroughly to ensure even baking. Grease and line two eight-inch round cake pans with parchment paper pressed flat to the bottom.

Whisk the dry ingredients together in a large bowl by sifting cake flour baking powder and baking soda until evenly blended. This prevents lumps and ensures a tender crumb.

Cream the butter and sugar together for four to five minutes on medium speed until pale and fluffy. This incorporates air for a lighter texture.

Add eggs to the mixture one at a time making sure each is fully blended before the next. Drizzle in cotton candy flavoring right after the eggs.

Alternate adding the dry mixture and whole milk to the butter mixture starting and finishing with the dry ingredients. Blend gently until just combined so the batter stays tender.

Divide the batter between the two pans and swirl pastel gel food coloring through each one with a toothpick for a marbled effect if you like.

Bake the Cake:

Place both pans in the center of your preheated oven and bake for twenty five to thirty minutes. The cakes are done when a toothpick inserted in the center emerges clean.

Let cakes cool in the pans for ten minutes then turn out onto wire racks to cool completely. This prevents soggy bottoms.

Make the Buttercream Frosting:

Beat unsalted butter on medium speed until smooth and creamy. This can take three to four minutes.

Gradually work in the powdered sugar a cup at a time with the mixer on low so you do not create clouds of sugar.

Add vanilla extract and if using a dash of cotton candy flavoring. Pour in heavy cream bit by bit until you reach a soft spreadable texture.

Assemble the Cake:

Set one cake layer on a serving plate. Cover the top with a thick layer of frosting using an offset spatula for even spreading.

Position the second cake layer on top. Apply a thin crumb coat of frosting over the entire cake and chill for twenty minutes to help seal in crumbs.

Finish with a final coat of frosting smoothing it carefully for a polished surface.

Decorate with Cotton Candy:

Hold off adding cotton candy until just before serving to keep it fluffy. Arrange clouds of candy on top and around the edges.

Add sprinkles edible glitter or pastel candies at the base for extra festive sparkle.

Save

Cotton candy flavoring is my secret for a true carnival taste. I love how my family gathers in the kitchen to watch as I swirl pastel colors into the batter—everyone wants to help decorate with the candy floss at the finish.

Storage Tips

Wrap the cake tightly and refrigerate if making more than one day ahead. The cake stays moist for two to three days in the fridge. Store leftover decorated pieces in an airtight container to keep the cotton candy from absorbing moisture and melting.

Ingredient Substitutions

If you cannot find cake flour blend two and a quarter cups all purpose flour with a quarter cup cornstarch for a similar result. Almond or oat milk can replace whole milk for a lighter texture. Swap store bought cotton candy for homemade if you have a cotton candy machine and want extra freshness.

Serving Suggestions

Serve this cake alongside fruit punch or pastel drinks for a whimsical dessert table. For a dramatic slice use a hot dry knife to cut and show off the marbled interior. Add small cupcakes topped with the same frosting and cotton candy for extra variety and a playful touch.
