The other day, I needed to use up Coconut Yoghurt which I had bought for my Vegan friends. I tried to make Yoghurt Soufflé Cake based on my Japanese Soufflé Cheesecake. I added whole 500g Coconut Yoghurt and the cake was too soggy. Today I tried gain, but used my homemade Greek Yoghurt and I added 1 cup only. It rose well and I liked the flavour. But I made a big mistake. I took out the cake straight away and it sank!!! You should leave the cake in the oven and cool it slowly. I knew that. Why did I take it out?

Cake Tin

18cm Round Cake Tin


Bowl 1
4 Egg Whites *at room temperature
1/4 cup Caster Sugar *DO NOT add yet

Bowl 2
1 cup Unsweetened Greek Yoghurt
1/4 cup Caster Sugar
1 pinch Salt
Zest of 1 Lemon
1 tablespoon Lemon Juice
4 Egg Yolks *at room temperature
1/4 cup Plain Flour
1 tablespoon Corn Starch

  1. Preheat oven to 150°C. Line the base and sides of a 18cm round cake tin with baking paper. The baking paper on the sides need to be at least 10cm in height.
  2. To help the cake to rise well, butter the baking paper on the sides. Add a small amount of Caster Sugar to coat the sides, shaking out any excess. *Note: This can help to avoid the cracked cake top.
  3. Place the cake tin in a roasting pan. *Note: If you use a springform cake tin, tightly cover the bottom of the cake tin with foil so that water won’t get in.
  4. Bowl 1: Beat Egg Whites, using an electric mixer, until soft peaks form. Gradually add Caster Sugar, beating well, until thick and glossy and Sugar is well dissolved.
  5. Bowl 2: Using the electric mixer you used to beat Egg Whites, beat the mixture until smooth and creamy. Gradually fold in the Egg White and gently combine.
  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. Turn off the oven. Leave the cake in the oven, with the door ajar for 1 hour, and cool slowly. When it is cool enough (room temperature), place in the fridge to chill in the tin. *Note: When you take out the cake straight away, the cake sinks just like the cake in the above photo. 😓 It was supposed to look like the cake below.
  8. Once the cake is chilled, it should be firm enough to flip using your hand. Gently peel the baking paper on the bottom, place it on the plate, then remove the paper on the sides.
