This extra moist and extra soft Sponge Cake is almost a Soufflé. It’s not a very sweet cake. Enjoy it cold or warm, with or without whipped cream and fresh berries. Lemon Curd would be nice, too. You would definitely wish to have a cup of tea.

Cake Tin

20cm Round Cake Tin


70g (120ml) Plain Flour *OR Self-Raising Flour
20g (2 tablespoons) Corn Starch Flour
90ml Milk
60g Butter
5 Egg Yolks *room temperature

  2. Place the cake tin in a roasting pan. *Note: If you use a springform cake tin, cover the bottom of the cake tin with foil so that water won’t get in.

  4. Combine Flour and Corn Starch in a large bowl. Add the hot Milk & Butter mixture and use a whisk to mix well. Add Egg Yolks and Vanilla, and mix well.

  6. Pour the mixture into the prepared cake tin. Pour boiling water into the roasting pan about 1-2cm deep. Bake for 60 minutes or until cooked through.
  7. Take out to a wire rack to cool, or enjoy it while it is still warm.
