Mix all the ingredients listed in the filling to make the filling.
For the dough, mix the butter, flour and sugar with your hands. Add vanilla and lemon, make a well and add two eggs in the middle. Add a little bit of warm water until the dough becomes solid.
The dough should be soft, so be gentle. Add a layer of dough on the bottom, make sure it covers the edges. Then add the filling, and add a top layer of dough to cover the cake. Make sure the cake is sealed. Paint with one egg.
Bake it in the oven at 180°C fan forced for approximately 30-35 minutes or until brown.
