As of December 2015, no diet hot chocolate K-Cups exists. Keurig offers four different types of cocoa K-Cups. Swiss Miss produces a milk chocolate K-Cup; Cafe Escapes produces both dark and milk chocolate drinks; and, Starbucks produces a unique, salted-caramel, hot cocoa option.
There are a number of additional off-brands that produce hot chocolate K-Cup pods, including Dunkin Donuts, Coffee For Less, Grove Square and Big Kat Coffees. However, these hot cocoa options do not include diet, fat-free or sugar-free selections.
Hot chocolate K-Cups were first introduced in late 2014. Depending upon the version of the Keurig, a user must select a specific mode for hot chocolate.
