The Kit Kat bar, as far as I know, is the chocolate bar with the widest variety of any candy bar in the world. Most of these variations come from the Japanese version of the Kit Kat. This one however has its origins in Europe, and as a Kit Kat variation goes the addition of Hazelnut Cream is not that creative. One might simply call this particular bar Kit Kat's take on Nutella or a Ferrero Roche.
Although I don't really find this bar to be that creative, I do find it pretty tasty. After first biting into the bar the texture of the wafers mixed with the chocolate dominated everything. It dominates so much at first that I doubted that I would taste the hazelnut at all. But after a few chews the hazelnut flavour works its way into the mix, eventually leaving you with a really nice hazelnut aftertaste.
I think the key to this bar working so well is a great ratio of every single element. Although they did pull out a wafer in order to fit in the Hazelnut, it didn't change the nice texture one expects from a Kit Kat bar. The chocolate pretty much stayed the same, and the flavour of the hazelnut is nicely balanced to not destroy the Kit Kat-ness of the bar.
If you're a fan of chocolate and hazelnut together, and also a Kit Kat fan, this could be the bar for you. Sure putting hazelnut in chocolate isn’t a brand new idea, but it’s an idea that does work.
