The Bake Off returns and for the first time ever, the tent welcomes a baker's dozen to do battle. Mel Giedroyc and Sue Perkins coax them through their baking trials, all the while under the scrutiny of the inimitable judges Mary Berry and Paul Hollywood. With a range of baking styles and personalities, the Bake Off tent is packed with the best amateur bakers from around the country; from space engineer to student, teacher to dentist, psychologist to carpenter. But after ten weeks of whisking, crimping and piping, only one can emerge victorious. This time, nobody is safe because Mary and Paul may decide to lose not one but two bakers at any time.

One week down and the remaining 12 bakers have 9 weeks and 27 gruelling challenges to get through before they can be crowned Winner of the Great British Bake Off. But having survived cake, now they battle bread.

It's week three, and the heat in the kitchen is already too much for some, as the remaining 11 bakers get ready to deal with desserts.

It's week four in the tent and the baking is getting serious, as the remaining bakers put on their pinnies to pimp up pies and tarts.

Almost halfway through the Bake Off and the remaining eight bakers are faced with biscuits and traybakes.

It is week six in the tent and time for sweet dough week - but will it prove bittersweet for the bakers?

With only six bakers left in the tent the stakes are getting higher and this week they face pastry.

It is the quarter final and there are just five bakers left. In the last seven weeks they have been tested on normal cakes, breads, pastries, pies and puddings so the judges are upping the ante. This week's challenges test them on how they cope working with unconventional flours and unusual desserts which push their creativity to the max.

It is the semi-final and there are just four bakers left. This round is the French round and the all-female semi-finalists have just three French bakes standing between them and a place in the final.

Each year thousands of people apply to The Great British Bake Off and only a handful are chosen, but what exactly is it like to take part? Talking candidly about their experience, the Class of 2012 return to the Bake Off tent to give a special insight to life inside the tent.

It's the final of The Great British Bake Off! 13,000 applicants were narrowed down to 13 of Britain's best amateur bakers, and the 13 became three. There are just three final challenges standing between the bakers and the title of winner of the Great British Bake Off. Mary and Paul have chosen the final challenges to test the bakers on the areas in which they wanted to see how far they had grown in skill and creativity.

Mary and Paul take over the tent for the ultimate baking masterclass. Mary makes a whole orange cake and angel food cake, Paul makes breakfast muffins and olive bread sticks, and together they make a chocolate cake showstopper.

Paul and Mary show what they would have done in dessert and pie challenges. Mary: 'Tipsy Trifle', floating islands and 'Wobbly Apricot Tart'. Paul: custard tarts and spanakopita.
