- Why did it collapse in the oven?
- You opened the door too soon, and the sudden drop in temperature caused the still weak structure to collapse.
- Why is it flat and dense?
- You mixed the flour into the foam for too long or too roughly, knocking out all the air.

Instructions
Preheat the oven to 180°C (conventional top/bottom heat). Line the bottom of a baking tin with baking parchment, but DO NOT butter the sides.
Separate the eggs. Not a single drop of yolk must get into the whites! Whisk the yolks with one-third of the sugar and the vanilla sugar until pale.
Whisk the egg whites with a pinch of salt into stiff peaks. When it starts to hold its shape, gradually add the remaining sugar and continue whisking until glossy and firm.
Using a spatula, gently fold the yolk cream into the egg white foam. Do not stir; instead, use large motions to lift the bottom over the top.
Sift the flour onto the mixture in several batches, and fold it in with the same gentle motions.
Pour the batter into the tin, smooth the top, and place immediately in the oven. Bake for approx. 20-25 minutes. Do not open the door for the first 15 minutes!
Test with a skewer. If clean, remove and let cool on a wire rack.
