GBBO: An Extra Slice will follow the contestants behind the scenes, with exclusive footage and moments not seen in the show.

GBBO bakers who leave the show will join Brand to relive some of their best and worst moments.

She will also be joined by celebrity fans of the show who will offer their opinion on each week’s tasks (as well as getting to try some ambitious bakes).

Jo Brand said “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 that brings."

Keeping with the baking theme,Channel 4 has also commissioned Paul Hollywood's new baking show, A Baker's Life (w/t) from Love Productions.

Baking has always been in his roots and this series will allow viewers to get to know the real Paul Hollywood who, following in the footsteps of his father and grandfather, has always earned his crust through baking bread.

Hollywood will visit the kitchens that have inspired him over the years, cooking some new treats and reminiscing over the recipes that represent key moments in his life.

Channel 4's Head of Factual Entertainment Kelly Webb-Lamb 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. 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."

Broadcast has reported that the new series will run for an extra 15 minutes.
