The oven timers have dinged, the judges have deliberated, and another week of Bake Off drama has concluded. But the conversation is far from over! An Extra Slice returns for its thirteenth helping of hilarious commentary, baking triumphs, and soggy-bottomed disasters. Hosted by the magnificently dry Jo Brand, this is the ultimate post-show parlour where fans, funnypeople, and failed bakers gather to dissect every detail with a generous dollop of humour.

It’s the perfect chaser to the main event—a warm, witty, and utterly chaotic celebration of the best and worst from the tent, featuring your favourite bakers, unforgettable audience bakes, and celebrity superfans sharing their own culinary confessions. Consider it the best bakery-themed book club in Britain.

The Great British Bake Off – An Extra Slice Season 12 Complete cast guide

– Jo Brand as HOST

The incomparable Jo Brand returns to her rightful place behind the desk, presiding over the chaos with her signature blend of bone-dry wit and palpable warmth. She is the nation’s favourite baking agony aunt, offering a sympathetic sigh for every collapsed soufflé and a perfectly timed, withering one-liner for every bout of tent-based melodrama. Her hosting style is less an interview and more a series of hilarious therapy sessions for the bakers.

Brand’s genius lies in her ability to mine comedy from the gentlest of places. Whether she’s marveling at the audience’s most bizarre show-and-tell bakes, gently ribbing a celebrity guest, or sharing a world-weary anecdote from her own kitchen disasters, she makes every moment feel like a chat with your funniest, most no-nonsense friend. She is the steady, chuckling heart of the entire affair.

– Tom Allen as SELF

The brilliantly quick-witted and impeccably dressed Tom Allen returns as the show’s resident commentator and Jo’s impeccable foil. Allen’s role is to float through the audience, microphone in hand, extracting hilarious baking horror stories and delivering his gloriously camp and astute observations on the week’s events. His ability to find the absurdity in every situation is unmatched.

Allen provides the show’s metropolitan, dandyish energy, a wonderful contrast to Brand’s deadpan delivery. His interviews are masterclasses in finding the funny without being cruel, celebrating the sheer British eccentricity of people who spend their weekends crafting biscuit replicas of famous landmarks. He is the show’s effervescent sparkle.

– Jonathan Ross as GUEST

The legendary broadcaster and talk show host Jonathan Ross brings his infectious enthusiasm and larger-than-life personality to the guest sofa. A known superfan of the main show, Ross isn’t just there to promote a project; he’s there to geek out over pastry and puns. Expect him to have strong, and likely very funny, opinions on who deserved Star Baker and whose bake belonged in the bin.

Ross’s presence guarantees energy and anecdotes. He will undoubtedly share tales of his own disastrous attempts at home baking, engage in playful banter with Jo and Tom, and revel in the audience’s most outrageous creations. His sheer joy at being there is contagious, making him the perfect guest to kick off the new season.

The showstopper is over. The post-mortem is here. Catch An Extra Slice on Channel 4, Fridays from September 5, 2025.
