Hi Rabbi Bartfeld,
Hope all is well. A few questions:
1) What is the beracha on chocolate that has wafer in it (like Klil or Kit Kat) is it mezonos or shehakol?

A. 1) The general rule in brochos is that whenever there is an ikar or primary food, and with it a tofel  or subordinate food, we make the blessing on the ikar and exempt the tofel (Brochos 44a, Shulchan Aruch O.H. 212:1.)
Most often when mezonos is eaten together with another food, we consider it to be primary and the other only as an enhancer. (Mishna Berura ibid. 6)
Horav Shlomo Miller’s Shlit’a opinion is that on chocolate bars that contain a layer of mezonos, like a wafer either on the inside or as a significant cover on the outside, a single mezonos brocho is recited.
