|Preheat the oven to 180°C (356°F).
Place the flour, margarine, egg yolks, vanilla sugar and 2 tablespoons of sugar in a medium mixing bowl, and mix until a crumbly dough is formed.
Pour the crumbles into a 26cm spring pan and use your fingers to press the dough, until it covers the bottom of the pan evenly.
Bake in the center of the oven until the crust is golden, about 15 minutes.
While the crust is baking, whip the egg whites and the remaining 2 tablespoons of sugar, to a soft pick, and set aside.
Also prepare the apple filling and set aside.
When the crust is golden, remove it from the oven.
Pour the apple filling on top of the crust and spread evenly.
Pour the whipped egg whites on top of the apple filling and use a spatula to spread it evenly.
Place the cake pan on a parchment lined baking sheet, place it back in the center of the oven and bake for 20 minutes.
Rotate the pan and bake until the top is golden brown, about 20 more minutes.
Remove the pan from the oven and let cool to room temperature.
Refrigerate for at least 4 hours before serving.
The cake can be served at room temperature. However, it tastes better when it is cold.
