Fluffy Castella Cake Recipe

Castella cake is a hallmark of Japanese baking: soft, airy, and subtly sweet, yet deceptively simple in appearance. Achieving its signature texture requires precision,whipped eggs, gentle folding, and low-and-slow baking. This recipe transforms classic ingredients into a cloud-like sponge with a golden crust, demonstrating how technique elevates humble components into a sophisticated dessert.

Ingredients List

• 6 large eggs, room temperature
• 3/4 cup granulated sugar
• 1/4 cup honey
• 1/4 cup whole milk
• 1 cup all-purpose flour, sifted
• 2 tablespoons unsalted butter, melted
• 1/4 teaspoon fine salt

Step-by-Step Instructions

Step 1: Prepare Pan

Preheat oven to 320°F (160°C). Line a 9×5-inch loaf pan with parchment paper, ensuring the sides extend above the pan for easy release.

Step 2: Whip Eggs and Sugar

In a large bowl, beat eggs on medium speed. Gradually add sugar and continue whipping until mixture triples in volume and forms ribbons when the whisk is lifted.

Step 3: Incorporate Honey and Milk

Warm honey and milk slightly and fold gently into the egg mixture. Use a spatula and gentle strokes to maintain aeration.

Step 4: Fold in Flour

Sift flour and salt over the mixture. Carefully fold in small batches, turning the bowl and using a gentle cutting motion to avoid deflating the batter.

Step 5: Add Melted Butter

Drizzle melted butter along the side of the bowl and fold just until combined. Avoid overmixing.

Step 6: Bake Slowly

Pour batter into the prepared pan. Tap gently to remove large air bubbles. Bake for 50–60 minutes, until a skewer inserted in the center comes out clean and the top is golden.

Step 7: Cool Gradually

Remove from oven and immediately lower the oven temperature to 150°F (65°C), leaving the cake inside for 5 minutes to prevent shrinkage. Remove from pan and cool on a wire rack.

FAQs

1. Can I use cake flour instead of all-purpose flour?
Yes. Cake flour will produce an even lighter, more delicate crumb, ideal for an airy Castella.

2. Why does my Castella cake shrink after baking?
Overbaking or rapid cooling can cause shrinkage. Slow cooling and gentle oven temperature adjustments prevent this.

3. Can I make Castella in a round pan instead of a loaf pan?
Yes, but adjust baking time slightly and monitor the center for doneness to maintain its soft texture.
