Directions
1. Step
Separate the eggs, placing the yolks in a bowl.
2. Step
In a saucepan, gently heat milk (85 g) and vegetable oil (65 g) over low heat for about 1 minute. Gradually whisk in cake flour (50 g), cocoa powder (25 g), and vanilla extract (4 g) until smooth. Add the egg yolks and mix until fully combined.
3. Step
In a separate bowl, beat the egg whites with sugar (75 g) using an electric mixer until stiff peaks form. Gently fold the yolk mixture into the whipped egg whites, ensuring it is evenly combined.
4. Step
Pour the batter into a 16.5 cm x 16.5 cm square baking pan (no. 2).
5. Step
Place the baking pan inside a larger pan filled with hot water to create a water bath. Bake in the microwave oven at 150°C (300°F) for 60 minutes.
