Crush cookies into very small pieces

Preheat oven to 175 degrees celsius

Butter a cake pan

Mix cookies with a pinch of salt and melted butter

Put the mix into the cake pan and press into the pan using something flat like a jar

Bake for 15min, then take it out and let it cool off a bit

While waiting prepare the filling

Whisk the cream cheese for 2-3min until it‘s creamy

Add sugar, vanilla sugar, vanilla pulp from the vanilla pod, lemon juice, lemon zest and crème fraîche and mix well

Beat the eggs separately in another bowl

Carefully mix the eggs with the other ingredients

Add filling to the cake pan

Bake for 45min and add an oven-safe pan filled with water into the oven (so the cake doesn‘t dry out and/or get too much colour)

When you take out the cake the middle still needs to be jiggely

Add flour and mix well
