If you've ever rolled your eyes at the sight of supermarkets stacking the mince pies high in September, look away now: The Great British Bake Off star Mary Berry has released a Christmas recipes app.

Published by Hachette subsidiary Headline Publishing Group, the £1.99 app promises "15 of Mary Berry's reliable, step-by-step festive recipes", from traditional roast turkey through to an aubergine five-nut roast.

Released for iPhone and iPad, the app includes shopping lists, cooking instructions and timers: up to three in the iPad app, although iPhone owners will have to make do with one.

The app is not available for Android smartphones and tablets, although an e-book version of Hachette's Mary Berry's Christmas Collection can be pre-ordered on the Google Play store for those devices.

The app is branded as Berry's rather than The Great British Bake Off, the BBC show that has won the cookery writer and broadcaster a new generation of fans with her judging and masterclasses.

The show itself has already spawned an official app released by Random House in August 2012, which offered 60 recipes drawn from two spin-off books that had already been published.

The latest series of The Great British Bake Off has been a ratings success for BBC2, attracting 5.85m viewers to its 3 September episode and regularly beating shows aired in the same slot on BBC1 and ITV.

Its app and Mary Berry's new release are part of a wider trend for cookery apps fronted by chefs and presenters.

Jamie Oliver has collaborated with British developer Zolmo on several apps, including Jamie's 20 Minute Meals and Jamie's Recipes. At the MIPTV conference in April 2013, Zolmo said the latter had been downloaded more than 8m times.

Other branded cookery apps include Nigella Lawson's Nigellissima, Gordon Ramsay's Cook With Me and Gino D'Acampo's Eating Italian.

Meanwhile, Raymond Blanc recently provided recipes for iPad app Henri Le Worm, which aims to get children interested in cooking, and also featured voice narration from Simon Pegg.
