Former Great British Bake Off (GBBO) finalist Ruby Tandoh will release her first recipe book, Crumb, in September.

Published by Chatto & Windus, part of The Random House Group, Crumb is described as “unfussy yet delectable”, and appropriate for novice and seasoned bakers.

In a statement, Tandoh said that she wants to the book to “have the approachability and naturalness that you’d expect from a friend helping you out in the kitchen”.

She added: “I’m overjoyed to be writing this book. Although I’ve only been baking in earnest for a couple of years now, this book will be the product of a lifetime of poring through weekend recipe supplements, scrawling notes in cookbooks, sketching cakes in homework margins and stopping at the window of every bakery I’ve ever passed.”

Poppy Hampson, senior editor, said: “Ruby is astonishing: an emerging and undeniable talent as a baker, a writer and a role model. We are proud and excited to welcome her to our list.”

Tandoh entered the fourth series of the BBC2 show as a second year philosophy and art history degree student at UCL.

She quickly impressed judges Mary Berry and Paul Hollywood  with her creative approach to ingredients and flavour.

She was beaten by Francis Quinn, who is also reported to be working on her first book.

Previous winners John Whaite, Edd Kimber, Joanne Wheatley, as well as season three finalist James Morton, have all released bakery books following their success on the show.

Tandoh is now a weekly food columnist for The Guardian, and will join British ELLE magazine from April 2014 as a monthly columnist.
