This doesn't scream peanut and it's even less distinct than in the treat, but it does seem to make the difference in cutting the sweetness of the Bar. The finish is still sweet, but it's just ever so much more interesting getting there.
Thin, only lightly sweet, but with a nutty finish and some mellow cacao. It doesn't really make me think of a candy bar, but it seems all the more drinkable for it.
