A dozen new bakers have entered a brand-new bubble in the nation's most famous tent. Noel Fielding and Matt Lucas lead the latest batch of bakers through 30 brand-new challenges set by judges Paul Hollywood and Prue Leith.
For our remaining bakers it's crunch time in Biscuit Week, kicking off with their twist on filled brandy snaps for the Signature.
Next, they produce a jammy childhood favourite in the Technical and finally, in the Showstopper, they put their design and engineering skills to the test to create an interactive toy made exclusively from biscuit.
Three challenges, but only one baker can be crowned star baker. Who will be top cookie and who will crumble under the pressure and leave the tent?
The Great British Bake Off continues Tuesday at 8pm on Channel 4.
