There are obviously regional differences for Käsekuche. I tend to make one that stems from the Gruyére region.
Blatterteig- round to fit a 24cm pie pan
5dl doppel rahm (créme double de Gruyére- can be found in Migros by the creams in the dairy case)
1dl milk
1 tablespoon Flour
2 egg yolks
4 eggs
250g Gruyére Cheese- the sharper the better

salt, pepper & nutmeg
Beat the creme, egg yolks & eggs together. Add in flour & milk . Mix in some salt, pepper & nutmeg for taste.
Butter the pie pan and lay in the blatterteig. With a fork seer the blatterteig a couple of times. Spread evenly over the blatterteig the cheese. Pour the egg mixture on top. In a pre heated oven, bake for 40 minutes at 200°. The top of the käsekuchen may brown a bit, but that is normal.
