The confectioner is introducing Cadbury Wishes (rsp: 59p), star-shaped milk chocolates with aerated centres, which will roll out in September.
The NPD was created to celebrate Cadbury's partnership with Make-A-Wish Foundation, and 10% of all Wishes profits will be donated to the charity.
This year's festive line-up will also feature Koko by Cadbury Assorted Truffles (rsp: £3.99) and "warmer, more traditional" packaging updates for the Selection box range and Snow Bites.
"Innovation and excitement are key in this segment, as consumers expect new news every season," said a Cadbury spokeswoman.
Cadbury has pledged to donate £400,000 to Make-a-Wish Foundation over a three-year period.
