Kat Duos Dark Chocolate and Mint are a flavour combination that was simply "mint" to be! The Dark Chocolate and Mint creme flavours make a sensational pairing in this new version of the crunchy break-time snack you know and love. Kit Kat's crispy wafers have been dipped in decadent dark chocolate on the bottom and dipped in a refreshing mint creme on top resulting in a striking two-tone Kit Kat.
