For the dough, sieve the flour into a bowl. Add sour cream, salt, butter and dry yeast and work with the dough hook to a smooth dough. If necessary knead again briefly with your hands on a work surface. This yeast shortbread can be processed straight away.
Cut the camembert, zucchini and ham into very small cubes. Fry the ham in the oil a little and then let it cool down a little. Then put everything together in a bowl. Mix in the sour cream and eggs and season with salt and pepper. (If you have to go quickly, you can use the ham without searing it.)
Roll out 2/3 of the dough in a greased springform pan (24 cm) and pull up one edge. Pour in the mixture and put the rest of the dough on a grid.
Bake the cake in the preheated oven at 175 degrees for about 40 minutes.
