First, preheat the oven to 180 °C, prepare a baking tray (20 cm × 30 cm) and line it with baking paper.

Separate the eggs into whites and yolks. Whisk the egg whites in a tall bowl until stiff peaks form (2–3 minutes) and whisk the yolks with sugar in a larger bowl until foamy (2–3 minutes). Then add oil, flour, baking powder, and cocoa to the yolks. Mix until smooth, then carefully fold in the egg white snow with a wooden spoon.

Pour the finished batter onto the baking tray and bake for 15–20 minutes at 175–180 °C. Then remove it from the oven and let it cool to room temperature (approx. 1 hour).
