🍰 Japanese Castella Cake Recipe (Honey Sponge Cake)
Introduction
Japanese Castella cake is a soft, moist, and slightly sweet sponge cake that originated from Portugal but became a beloved dessert in Japan. Known for its delicate texture and rich honey flavor, Castella is made using simple ingredients: eggs, sugar, flour, and honey. What makes it unique is its smooth crumb, golden top, and slightly chewy bottom.
This cake is popular for tea time, gifts, and special occasions. With the right technique, you can recreate this bakery-style cake at home.
🧾 Ingredients
- 6 large eggs (room temperature)
- 1 cup (200g) granulated sugar
- 2 tablespoons honey 🍯
- 2 tablespoons warm milk 🥛
- 1 cup (120g) bread flour (or all-purpose flour, sifted)
- 1 teaspoon vanilla extract (optional)
🍳 Equipment
- Mixing bowls
- Electric hand mixer or stand mixer
- Sifter
- 8-inch (20 cm) square or rectangular cake pan
- Parchment paper
- Spatula
🔪 Preparation Steps
Step 1: Prepare the Pan
Line your cake pan with parchment paper. Make sure the paper extends above the edges of the pan. This helps the cake rise evenly and prevents sticking.
Step 2: Warm the Eggs and Sugar
Crack the eggs into a mixing bowl and add the sugar. Place the bowl over a warm water bath (not boiling) and whisk gently until the mixture becomes slightly warm (around body temperature).
This step helps the eggs whip better and creates a fluffy texture.
Step 3: Whip the Egg Mixture
Using a mixer, beat the eggs and sugar on high speed for about 5–7 minutes until the mixture becomes thick, pale, and triples in volume.
You should reach the “ribbon stage” — when you lift the whisk, the batter falls slowly like a ribbon.
Step 4: Add Honey and Milk
Mix the honey with warm milk, then gently add it to the batter. Fold carefully using a spatula to keep the air in the mixture.
Step 5: Add the Flour
Sift the flour into the batter in small portions. Fold gently after each addition. Do not overmix, as this can deflate the batter.
Step 6: Pour into the Pan
Pour the batter into the prepared pan. Tap the pan lightly on the counter to remove large air bubbles.
Step 7: Bake the Cake
Preheat your oven to 160°C (320°F). Bake for 45–55 minutes.
The top should be golden brown, and a toothpick inserted should come out clean.
Step 8: Remove Air Bubbles
During baking (around 10 minutes in), you can quickly open the oven and gently tap the pan to release air bubbles. This helps achieve the classic smooth texture.
Step 9: Cooling
Once baked, remove the cake from the pan immediately and drop it gently from a small height (about 20 cm) to prevent shrinking.
Wrap the cake while still warm with plastic wrap to retain moisture.
Step 10: Rest the Cake
For best results, let the cake rest overnight. This allows the flavor and texture to improve significantly.
