Preheat the oven to 200 °C.
Put the cream cheese, cane sugar, and cream in a bowl or food processor. Add a pinch of salt, the lemon zest, and the vanilla seeds. Mix together until a homogeneous smooth mass is formed. Stir in the eggs one by one and finally add the sifted flour.
Grease a cake pan and line it with baking paper. Press it well into the edges.
Pour the mixture in. Push and fold the baking paper well against the baking pan so it doesn't bake into the cake later.
Place in the oven for 1 hour at 200 °C. After 30 minutes, lower to 175 °C.
Let it set in the refrigerator for at least 2 hours (but can also be overnight).
