Q. What is Horav Miller’s opinion on the correct brocho on cheese cake?
A. Much has been written by different Poskim in regards to what brocho or brochos should be recited on cheesecake. Mishna Berura (212: 1) rules that usually the dough is considered the primary ingredient and only mezonos should be recited even if there more cheese than dough, or if the cake is eaten mainly because of the cheese. However, if there is only a thin strip of crust, just to permit one to handle the cheese, the crust becomes secondary to the cheese and Shehakol should be recited.
Laws of Brachos (7: p. 219) writes in general the crust also adds flavor so the Bracha is Mezonos. However, if the crust is only meant to hold the cheese, the brocho should be Shehakol. See also Vezos HaBrocho (11: p. 92) and others.
Horav Shlomo Miller’s Shlit’a opinion is that due to the many different and changing factors involved and the different variations of this cake, preferably one should recite a brocho on a separate piece of certain mezonos and then on a certain shehakol, before eating the cheesecake.
