How to make:

1. Preheat the oven to 160°C (320°F). Place a baking tray with 1 cm of water in it in the oven.
2. Whisk all the ingredients in part A until smooth and well combined, then set aside.
3. Beat the ingredients in part B until stiff peaks form.
4. Gradually fold the part B mixture into the part A mixture using a spatula.
5. Pour the batter into a 20 cm diameter cake pan lined with parchment paper.
6. Bake using the au bain-marie technique (place the cake pan in a larger pan filled with water) for 60 minutes or until cooked through.
7. Remove from the oven, cool, and serve.
