Let’s get baking!
- Prep Time: 20 minutes
- Baking Time: 50 minutes
- Total Time: 1 hour 10 minutes
Main Ingredients
- 6 large eggs
- 1 cup bread flour or cake flour
- ¾ cup sugar
- 2 tablespoons honey
- 2 tablespoons warm milk
- 1 teaspoon vanilla extract
Optional Additions
- A pinch of salt
- Lemon zest for a refreshing twist
Baking Steps
1: Prepare the Baking Pan
Preheat your oven to 160°C (320°F). Line a loaf pan or square cake tin with parchment paper, ensuring the sides are fully covered.
2: Mix Honey and Milk
In a small bowl, combine warm milk and honey. Stir well until the honey dissolves completely. Set aside.
3: Beat the Eggs and Sugar
Crack the eggs into a large mixing bowl and add sugar. Using an electric mixer, beat the mixture until it becomes pale, thick, and fluffy. This step is essential for creating the airy sponge texture.
4: Add Dry Ingredients
Sift the flour to remove lumps. Gently fold it into the egg mixture using a spatula. Be careful not to overmix, as this can deflate the batter.
5: Add Honey Mixture
Slowly pour in the honey and milk mixture along with vanilla extract. Fold gently until everything is fully combined.
6: Bake the Cake
Pour the batter into the prepared pan and lightly tap the pan on the counter to remove air bubbles.
Bake for about 45–50 minutes or until the top turns golden brown and a skewer inserted in the center comes out clean.
7: Cool and Serve
Allow the cake to cool completely before slicing. For the best texture, wrap the cake and let it rest for a few hours before serving.
Slice into neat pieces and enjoy your homemade Japanese Castella cake!
Tips for the Perfect Castella Cake
Want your sponge cake to turn out bakery-perfect? Follow these simple tips:
- Beat the eggs properly: This creates the signature fluffy texture.
- Fold gently: Overmixing can make the cake dense.
- Use room-temperature eggs: They whip better and create more volume.
- Line the pan well: Castella cakes are delicate and can stick easily.
- Bake at a lower temperature: Slow baking ensures an even rise and soft texture.
