Also joining them will be EastEnders' Natalie Cassidy and Coronation Street and Emmerdale star Chris Bisson.
Meanwhile, the line-up has also been announced for the Great New Year's Bake Off for 2025, with a host of former contestants returning to the tent.
These include Kevin, Norman, Nicky, James, Lea and Peter.
News of the soap-themed Christmas special was first reported by The Mirror, with an insider telling the publication: "For the Signature challenge the bakers will be asked to put their own spin on the traditional yule log, and for the Technical they need to make delicate Christmas trees out of meringue.
"But as ever, the biggest challenge will come with the Showstopper, which will see them having to re-create one of their favourite festive soap storylines - in biscuit form. Will Wellard make an appearance? Could Sonia’s trumpet pop up? Perhaps we’ll see rum'n'raisin versions of the Woolpack or the Rovers. Absolutely anything is possible."
