The range includes Caramelised Almonds, Spiced Biscuit and Coconut Macaroons, available in 100g bars from Bestway and Dhamecha, retailing at £1.
Each bar also features a new matte film packaging.
Katy Clark, head of marketing at Ritter Sport, said: “Despite footfall down 30% over last year’s Christmas period due to COVID-19, the Winter Edition bars still saw a 95% total sell-through within a major high street retailer.
“A promising indicator of their performance and consumer demand.”
