Grease the springform pan with a little butter - distribute the breadcrumbs in the pan
Mix the butter and sugar until frothy and gradually add the 6 egg yolks. Then stir in the drained quark mixture, the semolina and the other ingredients.
Beat the 6 egg whites with a pinch of salt until stiff and fold into the mixture with a wide spoon - do not stir.
Pour the mixture into the mold, smooth it out and bake in the preheated oven at 175 degrees for 30 minutes.
Then take the cake out of the oven and carefully detach it from the edge of the pan with a long, flexible knife - this way the cake won`t collapse later!
Bake for another 30 minutes and cover the last 10 minutes with baking paper - so that the cake stays golden yellow and doesn`t get too dark.
Then open the oven and let it cool down slowly in the pan.
