Martha Collison is the youngest ever baker on The Great British Bake Off - she made it all the way to the quarter finals whilst studying for her AS Levels! Martha is a self-taught baker who started cooking at the age of eight - the result of her brave parents letting her loose in the kitchen and enjoying the (sometimes mixed) results. Since then her baking repertoire has grown no end, and she now writes a weekly column in Waitrose Weekend as well as her own blog. Her first book Twist is a Sunday Times bestseller. She loves spending time with her family, and is passionate about helping with charitable campaigns with Tearfund.
