The Great British Bake Off will run for 75-minute episodes when it is shown on Channel 4, giving audiences an hour of content plus ad breaks.
Fans had feared that regular breaks would mean the show ended up being much shorter than the BBC version.
But Channel 4, keen to keep the audience happy after the programme lost three-quarters of its original line-up, have ensured the running time remains the same.
The show is keeping its old format of signature, technical and showstopper bakes, and the famous tent will remain unchanged.
But Mel Giedroyc and Sue Perkins are being replaced by Sandi Toksvig and Noel Fielding, with Prue Leith in place of Mary Berry.
It was also confirmed today that Jo Brand has followed the show to Channel 4, and will present the spin-off programme The Great British Bake Off: An Extra Slice.
“As a completely mediocre baker myself, but lover of all things spongey and tarty, I am really looking forward to another Extra Slice and all the fun and frolics it brings,” she said.
Paul Hollywood, the only member of the original team to stay loyal to programme-makers Love Productions, has been rewarded with a new five-part baking series of his own.
A Baker’s Life “will allow viewers to get to know the real Paul Hollywood”.
Hollywood will visit the kitchens that inspired him and the chefs who taught him as the programme traces his life story from his father’s bakery business to the five-star hotels where he worked before joining Bake Off.
Kelly Webb-Lamb, head of factual entertainment at Channel 4, said: “The new series will feature Paul’s irresistible recipes and offer insight into the man from Merseyside whose baps and bloomers have made headlines.
“Love and Paul are already a tasty combination but we are delighted to be able to give the audience a fresh insight into Paul’s life before Bake Off, and how he became the brilliant judge he is today.”
