This isn’t your average sponge cake the method is part of what gives Castella its signature bounce and cotton soft bite. Here are tips I follow every time:
- Use room temperature eggs: They whip better and give more volume.
- Don’t overheat the oil: Just warm enough to blend the flour, but not hot enough to scramble the yolks.
- Always sift your flour: Even a few lumps can weigh the cake down or cause streaks.
- Fold, don’t stir: Keep your motions slow and careful to avoid deflating the airy meringue.
- Bake low and slow: High heat causes cracking 150°C and steam creates that smooth, glossy top.

Creative Castella Cake Twists
This cake is stunning in its simplicity, but here’s how I love to experiment with flavors without compromising texture:
- Matcha Castella: Add 1 teaspoon of sifted matcha powder with the flour for a subtle earthy twist.
- Honey infused: Swap out 1 tablespoon of sugar for honey for a deeper golden crust and natural sweetness.
- Lemon version: Add 1 teaspoon of lemon zest and a tiny splash of lemon juice for a bright finish.
- Layered with jam: Slice the cake horizontally and add a thin spread of fruit jam or citrus marmalade between layers.
- Mini Castella bites: Bake the batter in cupcake molds using the same water bath method for adorable, single serve treats.
