Celebrity Great British Bake-off stars Bolton's Sara Cox

Other big names include soap star Danny Dyer, former Doctor Who Jodie Whittaker and Spice Girl Mel B.

Hosts Alison Hammond and Noel Fielding will welcome 20 stars into the tent, where their efforts will be appraised by judges Paul Hollywood and Dame Prue Leith.

Sara will be entering the famous tent with fellow broadcaster The Reverend Richard Coles, Heartstopper star Joe Locke and The Last Leg’s Adam Hills.

She follows in the footsteps of fellow Boltonian Paddy McGuinness who has previously starred in the show.

Also among the hopefuls will be TV presenter Dermot O’Leary, broadcaster Gabby Logan, singer Paloma Faith and former Strictly Come Dancing star Oti Mabuse.

Whittaker and Faith will take on comedian Munya Chawawa and reality star Spencer Matthews in their episode.

Dyer will face off against comedian Rhod Gilbert, documentary maker Yinka Bokinni, and TV star Leigh Francis.

Mabuse and Logan’s episode will also feature comedians David O’Doherty and Suzi Ruffell, while O’Leary and Mel B will be joined by Radio 1’s Greg James and comedian Fern Brady.

Over two days the celebrities will face signature, technical and showstopper challenges as they compete in a bid to be crowned Star Baker at the end of their episode.

Adam said: “Walking into the tent feels like it should be accompanied by a choir of angels all singing.

“But to walk into it with the big S and the arrow and the 2 and the C at the front, which has now become an iconic image in and of itself, those two combined make you walk a couple of inches taller, I think.”

Taskmaster star Fern added: “I’m insanely competitive. I badly want to win. I was telling my boyfriend last night ‘You know the prize for this is rubbish, you just get an apron that says ‘Star Baker’’.

“He was like: ‘Are you joking, Fern? You would wear that all the time around the house."

Hammond previously appeared on the celebrity version of the show before joining as host alongside Fielding.

She said: “I’m totally in awe of this year’s celebrity bakers, all putting their baking skills, or in some cases lack of, under nationwide scrutiny to raise money for Stand Up To Cancer.

“As someone who proved to be something of a baking genius when I baked in the tent a few years ago, I was delighted to be able to show them the ropes and where the oven doors were.

“On your mark, get set, Bake for Stand Up To Cancer.”

Dame Prue Leith said, “I'm absolutely thrilled to share that we're serving up another delightful season of The Great Celebrity Bake Off for Stand Up To Cancer this spring on Channel 4. Brace yourself for a delectable lineup of bakers, each with their own unique flair in the kitchen – some are, admittedly, a bit more flour-savvy than others! Filming this show was a delicious dose of fun, sprinkled with some unforgettable baking moments. I can't wait for everyone to see it.”

Stand Up To Cancer UK, the joint national fundraising campaign between Channel 4 and Cancer Research UK, has raised millions of pounds to fund life-saving cancer research.

All the money raised by Stand Up To Cancer funds translational research, to help take discoveries from the lab and turn them into tests and treatments to benefit patients.

The Great Celebrity Bake Off for Stand Up To Cancer will be available to watch and stream on Channel 4 later this year.
