A 12-year-old Hampstead schoolgirl is hoping to raise up to �20,000 for a specialist ward at Great Ormond Street Hospital, by selling a cookbook of celebrities’ cupcake recipes.

Georgie Sussman felt inspired to raise money for Great Ormond Street because a four-year-old family friend has been receiving treatment there for a rare brain tumour.

The little girl, identified only as Lucy, lives in St John’s Wood and has had to travel to Arizona for specialist treatment.

However, Great Ormond Street is opening a new unit in 2012 to treat children such as Lucy who suffer from neurological conditions.

Georgie, a pupil at St Margaret’s School in Kidderpore Avenue, said: “The hospital is building a new ward for her but they need money for all the little extras such as beds for mums to stay in overnight. I thought about doing cupcake sales at school but then I worked out that I’d have to sell thousands to make enough money. So then I thought about writing a cookbook. My goal is to raise between �15,000 to �20,000 for the hospital.”

Georgie, who lives in Hampstead, came up with the idea of producing a cookbook of cupcake recipes because her mother, Meg, runs a cupcake business.

She wrote to family and friends asking if they would supply cupcake recipes and was astonished at the response she received. Word soon spread and a host of celebrities offered their favourite recipes too.

Among the famous names who have contributed culinary ideas for the book are Nigella Lawson, Raymond Blanc, Antony Worrall Thompson, Sophie Dahl, Gino D’Acampo, Richard E. Grant, Mel C, Patsy Kensit, Amanda Holden, Delia Smith and Pixie Lott.

For Georgie, the experience of publishing her first cookbook at just 12 has been an exciting one.

“I liked tasting the cupcake recipes and also receiving all the messages,” she said. “I’ve received letters from Ronan Keating, Mark Ronson and Pixie Lott.”

Mark Webster, headteacher of St Margaret’s School said: “Georgie has shown terrific initiative, determination and self-belief in putting this together. We’re all very proud of her achievements.”

The cookbook went on sale in time for Christmas and so far Georgie has sold 250 copies raising �2,500.
