Saw this at the supermarket the other day and decided to give it a go. It’s not a full bag of sweet potato ones, but rather half-and-half split with normal kit kat. (shrug)
There’s not a very strong sweet potato flavour from these, actually. They taste like a generic white chocolate type. They’re kind of like the kinako flavoured kit kat in that way. Though the taste isn’t strong, if you take a big whiff of it before chowing down, there is a definite baked sweet potato fragrance.
All in all, nice to try just so you can say HAW! I ATE SWEET POTATO KIT KAT, but don’t expect a whole lot.
