"The Great Celebrity Bake Off is a key ingredient in our Stand Up To Cancer recipe," Sarah Lazenby, head of formats and features at Channel 4, previously said. "We've seen the power of using comedy and entertainment to bring awareness and raise millions of pounds to fund pioneering cancer trials. We hope viewers will enjoy this year's line-up of famous bakers. There's never a dough moment as each bring something fresh and exciting to the tent."
