This Cotton Candy Pound Cake is ultra-buttery, tender, and delicately sweet with a nostalgic cotton candy flavor. Soft pastel swirls make every slice whimsical and eye-catching—perfect for birthdays, baby showers, and kawaii dessert tables.
Preheat oven to 325°F (165°C). Line a 9×5-inch loaf pan with parchment paper, leaving overhang, and lightly grease.
Cream Butter & Sugar
Beat butter and sugar on medium-high speed for 4–5 minutes, until very pale, fluffy, and aerated. This step is key for a light crumb.
Add Eggs
Add eggs one at a time, mixing well after each addition and scraping down the bowl as needed.
Combine Dry Ingredients
In a separate bowl, whisk together cake flour, baking powder, and salt.
Build the Batter
Add dry ingredients to the butter mixture in three additions, alternating with the milk. Begin and end with dry ingredients. Mix just until combined—do not overmix.
Flavor the Batter
Mix in cotton candy extract and vanilla extract until evenly incorporated.
Create the Pastel Swirl
Divide batter evenly into two bowls. Tint one pink and one blue using gel food coloring.
Spoon alternating dollops into the prepared loaf pan, then gently swirl with a skewer or knife.
Bake
Bake for 75–85 minutes, tenting loosely with foil after 50 minutes if the top browns too quickly.
The cake is done when a toothpick inserted into the center comes out clean or with a few moist crumbs.
Cool Completely
Cool in the pan for 15 minutes, then lift out and transfer to a wire rack. Allow to cool completely before glazing.
Make the Cotton Candy Glaze
Prepare the Glaze
In a bowl, whisk powdered sugar, 2 tablespoons cream, cotton candy extract, and salt until smooth.
Add remaining cream a little at a time until a thick but pourable glaze forms. Tint lightly with pink or blue if desired.
Glaze the Cake
Drizzle glaze over the cooled pound cake, allowing it to drip naturally down the sides. Let set for 15–20 minutes before slicing.
Notes
Cake flour is essential for a soft, bakery-style crumb. All-purpose flour will make the pound cake noticeably denser.
Fully cream the butter and sugar until very pale and fluffy—this step creates lift in an otherwise heavy batter.
Room-temperature ingredients (butter, eggs, milk) ensure a smooth batter and prevent curdling.
Cotton candy extract strength varies by brand. Start with the listed amount and adjust slightly to taste if yours is especially strong or mild.
Use gel food coloring only. Liquid food coloring can thin the batter and muddy the pastel swirls.
Swirl gently. One or two passes with a skewer is enough—over-swirling will blend the colors instead of marbling.
Tent with foil if needed. Pound cakes bake long; loosely cover after about 50 minutes to prevent over-browning.
Cool completely before glazing. A warm cake will absorb the glaze instead of allowing it to set on top.
For extra nostalgia, sprinkle pastel sanding sugar or cotton-candy-colored sprinkles over the glaze before it sets.
Flavor improves overnight. Store tightly wrapped at room temperature and enjoy the next day for the best texture and flavor.
