Due to this year's exceptional circumstances, the 12 new bakers entered a bubble for seven weeks in order to allow the competition to happen.
One of those was 31-year-old Lottie Bedlow, from West Sussex.
About Lottie, Channel 4 said: “Lottie’s Lancastrian great-grandmother was a fervent cake-baker – and for this reason Lottie believes that baking is in her blood.
“She has always had a fascination with cooking: when she was little, she watched cooking shows rather than playing with her toys and was often to be found making notes from cookery books.
“She calls herself a ‘perpetually frustrated perfectionist’ and, while her baking has become more refined over time, she hopes it retains an element of her dark sense of humour.
“When she’s not baking or busy with her job producing pantomime, Lottie will be playing computer games with her young cousins, or practising yoga.”
This year's Great British Bake Off will see the iconic tent remains the same, but there are 30 brand new challenges set by judges Paul Hollywood and Prue Leith.
Hosts Noel Fielding and Matt Lucas kick off the series with Cake Week. First, in the signature, the bakers get the opportunity to put their twist on the classic Battenberg.
Next, under the gingham cloth are the ingredients for the first technical; turning out a fruit sponge, that’s one of Paul’s favourites.
Finally, a showstopper that gives the bakers a chance to express their creativity, as they pay tribute to their heroes. An opportunity for the judges to see what inspires this year’s bakers, and whether they have the skills to translate it into cake.
Twelve bakers in the bubble. Three challenges. Only one will be crowned star baker, and sadly one will be going home.
