So, here's the concept of this particular treat. Take a Kit Kat bar; now take away one layer of wafer and one layer of that icing stuff between the wafers. Now replace the stuff you took away with a tiny thin cookie. I can't really imagine this being a bad idea; on the other hand, I also can't imagine it really changing the bar that much.
The thing is it really doesn't change the bar that much. The wafer is already a form of cookie, so to replace it with another cookie seems a little strange. It could work if the cookie that is replacing it has a distinct flavour or texture that was vastly different than the wafer and icing it's replacing, but in this case it's not. I mean it is a little different, but the chocolate and wafer that remain from the old Kit Kat really cover up this new cookie flavour.
The texture is a little noticeable if you think about it, but I had to eat at least three fingers before I could really tell. Now don't let this review lead you to believe that I didn't like the Kit Kat Cookies, in fact I loved it. The chocolate was great; the ratio of both cookies to chocolate was great as always. It's just it wasn't anything bold or different enough to make me want to buy this box of Kit Kat Cookies over just a regular Kit Kat.
