Castella Cake: Fluffy Japanese Honey Sponge Cake 🍯🍰

by

1. Prep the Pan

  • Line a 9×5-inch loaf pan with parchment paper, leaving overhang on the sides. Lightly grease with oil.

2. Whip Eggs & Sugar

  • In a large bowl, beat eggs and sugar with a mixer on high speed for 8–10 mins until pale, thick, and ribbon-like (when you lift the whisk, the batter should fall slowly and leave a trail).

3. Fold in Flour

  • Sift flour into the egg mixture in 3 batches, gently folding with a spatula after each addition (don’t overmix!).

4. Add Honey Syrup

  • Drizzle in honey-water mixture, folding gently until just combined.

5. Bake Low & Slow

  • Pour batter into the pan. Drop the pan lightly on the counter 2–3 times to remove air bubbles.

  • Bake at 320°F (160°C) for 50–60 mins until golden and a toothpick comes out clean.

  • Optional: After 15 mins of baking, quickly score the top with a knife for a flat surface.

6. Cool & Wrap

  • Immediately after baking, cover with plastic wrap (to retain moisture) and cool upside-down on a rack for 1 hour.

  • Slice with a serrated knife the next day for clean cuts.

💡 Pro Tips

đŸ”„Â Room-temp eggs whip better for maximum fluffiness.
đŸ”„Â Bread flour gives structure; cake flour makes it softer.
đŸ”„Â For extra moisture, brush the top with more honey syrup after baking.

❓ FAQs

Why did my cake sink?

  • Overmixed batter or underbaking. Ensure the toothpick test is clean!

Can I reduce the sugar?

Yes, but the texture may be denser (sugar helps stabilize the eggs).

How to store?

  • Room temp (wrapped): 2 days

  • Fridge: 1 week (microwave 10 secs to soften)

  • Freeze: 1 month
