There’s no wonder why castella cake is so popular in Japan. It’s got a moist and fluffy texture that makes you want to have a slice every day.

Cooking: 50 minutes
Total: 1 hour 10 minutes

  • 5egg yolks


  1. Stir instant coffee powder into warm milk until dissolved, then mix in your vegetable oil and vanilla extract.

  2. In a separate bowl, whip egg whites and add the sugar in three parts until it forms a stiff meringue. To get the stiff meringue, slowly add the egg yolks, one at a time, while mixing with a whisk.

  3. Sift the flour and cocoa powder into the bowl and fold/mix the batter with a rubber spatula until fully incorporated.

  4. Rub the insides of a rice cooker with cold butter or oil and add batter. Stir with a chopstick to release any big air bubbles.

  5. Cook the batter in the rice cooker for 50 minutes, or until cooked through.

  6. Cool and serve.
