Mmm, Tiramisu! I love the flavors of real Tiramisu so I basically knew that this Kit Kat flavor was going to be a winner, haha. As you can see this Japanese Kit Kat is white chocolate based, which makes sense for a dessert like this one, where the Mascarpone cheese is a big component. I have no idea how they do it, but there really was a coffee-soaked-vanilla-ish element in both the smell and the taste. This was definitely one of the better Japanese Kit Kats I've tried, and would love to have this flavor again!
