• 3 cups 375 g cake flour

Instructions

Make the Pound Cake

Prepare the Pan

• 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.

FAQ

Can I make this pound cake without food coloring?
Yes. The cake will still taste like cotton candy without the pastel swirls. It will bake up a soft, creamy vanilla color instead.

What brand of cotton candy extract works best?
Clear extracts designed for baking work best. Avoid oil-based candy flavorings, which don’t blend evenly into the batter or glaze.

Why does this recipe use both cotton candy extract and vanilla?
Vanilla rounds out the sweetness and keeps the cotton candy flavor from tasting sharp or artificial.

Can I turn this recipe into cupcakes or a sheet cake?
Yes. For cupcakes, bake at 325°F for 20–25 minutes. For a 9×13-inch cake, bake 55–65 minutes and glaze once cooled.

How long does the glaze take to set?
The glaze will set to a soft finish in about 15–20 minutes at room temperature but will remain slightly glossy and tender.

Is this cake overly sweet?
No. Despite the playful flavor, the buttery pound cake balances the sweetness so it’s rich without being cloying.

Can I serve this at room temperature?
Yes. This cake is best served at room temperature, when the crumb is soft and the flavors are fully developed.
