Ingredients:
6 large eggs
100g (1/2 cup) granulated sugar
60ml (1/4 cup) milk
60g (1/4 cup) unsalted butter
100g (3/4 cup) cake flour (or all-purpose flour sifted well)
1 tsp vanilla extract
1/2 tsp lemon juice (optional)
A pinch of salt
Instructions:
1. Preheat Oven:
Preheat your oven to 160°C (320°F). Line a square or round cake pan with parchment paper.
2. Prepare Egg Mixture:
Separate the egg whites and yolks into two large bowls.
In the yolk bowl, add sugar (half), vanilla extract, milk, and melted butter. Mix well.
Gradually sift in the flour and mix until smooth.
3. Whip Egg Whites:
Add lemon juice (optional) and salt to the egg whites.
Beat using an electric mixer until foamy. Gradually add the remaining sugar and beat until stiff peaks form.
4. Combine:
Gently fold the whipped egg whites into the yolk mixture in 3 parts. Use a spatula and fold carefully to avoid deflating the batter.
5. Bake:
Pour the batter into the pan. Tap the pan lightly to remove air bubbles.
Place the pan in a larger tray filled with hot water (water bath).
Bake for about 50-60 minutes or until the top is golden and a toothpick comes out clean.
6. Cool:
Remove from the oven and let the cake cool completely in the pan.
