Here we round up all the latest news and spoilers about the Great British Bake Off 2017 on Channel 4 this year.
Great British Bake Off start date and time
Channel 4 has now officially confirmed when The Great British Bake Off starts this year.
And a shift from the previous Wednesday night slot on BBC One, Channel 4's version will air on Tuesday nights.
The fifth episode begins tonight on Tuesday, September 26 at 8PM, running for 75 minutes which is longer than the typical hour on BBC but of course there will be adverts.
Meanwhile, The Great British Bake Off: An Extra Slice is returning with Jo Brand staying as host, airing on Thursday nights on Channel 4.
This week for it's time for puddings and Prue Leith and Paul Hollywood are looking for perfection.
The signature challenge is a steamed favourite. There's a staggering technical challenge where timing is everything and a multi-layered showstopper that's not to be trifled with.
Great British Bake Off 2017 judges
Restaurateur, food writer and novelist Prue Leith will be joining Paul Hollywood as judge of The Great British Bake Off when it returns to screens tonight on Channel 4.
Paul Hollywood said: “I could not be more delighted by who will be joining me on the show. Prue is a hugely respected culinary legend and Sandi and Noel are warm and utterly hilarious. I cannot wait to get back in the tent with the bakers.”
Prue Leith said: “I am just so thrilled to be joining Paul, Sandi and Noel on the biggest show on TV and I cannot wait to see what the real stars of the show – the bakers – are going to create for us. It is such an honour to be part of The Great British Bake Off team. “
Great British Bake Off hosts
GBBO hosts Sandi Toksvig OBE and Noel Fielding join judges Prue Leith and Paul Hollywood.
Sandi Toksvig OBE said: “It is an extraordinary honour to part of this national treasure of a show. Noel Fielding is one of the nicest guys in show business. The first time I met him I felt like I had met a rather wayward cousin whose take on the world made me laugh. The only down side is that he has much better dress sense that I do.
"I spend my daytimes on Channel 4 already so it will be a treat to be there in the evenings. I am so delighted to be working with Love Productions and Channel 4 on this best of British show.”
Noel Fielding said: "GBBO is one of my favourite shows. I’ve always loved brightly coloured cakes and Sandi Toksvig so this is a dream come true for me! It’s basically the double."
Great British Bake Off contestants
The Great British Bake Off moves to Channel 4 from next Tuesday as a brand new set of 12 bakers battle it out in 30 challenges over 10 weeks.
Judges Paul Hollywood and Prue Leith have set the tasks and will decide the star baker - plus which unlucky contestant is sent home - each week.
