Japanese Cotton Sponge Cake

Japanese Cotton Sponge Cake


This cake is so good that it’s hard to stop eating. The process of making the Japanese cotton sponge cake is similar to most of the sponge cake recipes. The recommended temperature and baking time is one of the most unreliable measurements in any recipes for cakes. Most of the ovens do not have a very accurate temperature indicator.


  • 60g butter, melted
  • 80g flour, sifted
  • 80ml full cream milk
  • 1 whole egg
  • 5 egg yolks
  • 5 egg whites
  • 120g caster sugar


  1. Line a baking pan and set aside.
  2. Melt butter ( you can use a microwave) and pour it into a mixing bowl.
  3. Add sifted flour and use a spatula to mix the flour and butter until well blended.
  4. Add milk and continue to mix.
  5. Add egg yolks, one by one, mixing as you go along, followed by the whole egg. Set aside.
  6. Using a handheld mixer, beat egg whites until foamy and add sugar.
  7. Continue to beat until stiff peaks.
  8. Pour the egg yolk mixture into the egg whites and fold to mix  until you do not see any streaks.
  9. Pour batter into the lined pan and bake at 150°C for 1 hour 50
    minutes in the middle rack  until a skewer inserted into the centre of
    the cake comes out clean.
  10. Remove the cake from the oven immediately and drop it from a height (about 12 inches ) onto your tabletop.
  11. Unmould the cake and leave it to cool completely before serving.
