Is it whipped cream based? I always stayed away from it before I was afraid of the heavy butter based cream on it.

Is your princesstårta the same as the swedish one? Whipped cream mixed with vanilla cream (or custard, not sure what the accurate English word is for it) and possibly one layer with usually strawberry jam, covered in whipped cream with a sheet of marzipan covering the entire thing? With normal vanilla cake layers between.

We don't have it in Czechia, maybe in Ikea😅 Loads of similar cakes of course, but we had this one only on vacation. 😊
