Tiramisu really isn't one of my favorite desserts. I love coffee, but I don't like coffee-flavored desserts and candies very much. But when I ordered the Matcha Tiramisu bars, I figured I might as well order a couple normal Tiramisu bars, too.
The package boasts a "harmony of coffee and cheese" and says that it was made with 0.4% coffee. The last coffee flavored KitKat that I tried was pretty bad, so I was a little worried, but I was pleasantly surprised.
The bar had a strong coffee scent, and when I broke it apart, it was stronger. The chocolate was very creamy, and by itself was mild. The wafers by themselves, however, tasted very strongly of coffee, suggesting that the cream between the wafers was the main source.
It actually did taste like tiramisu! I didn't even mind the coffee flavor for once, because it wasn't overpowering. Maybe it's just because the pack only had one bar, but it wasn't sickeningly sweet, either. Much better than the Caramel Macchiato McFlurry flavor from last year.
