The Devil's Food cake, which dwarfed guests at 10ft high when on its table, was made at the personal request of the bride.

It was served at the reception at Windsor Castle following her marriage to Prince Edward in St George's Chapel on Saturday afternoon.

Linda Fripp, 52, whose food design company Upper Crusts made the giant chocolate creation, said: "It was a delicious cake made with lots of chocolate, following a recipe I've evolved over years and years.

"Every single bit of it was eaten at the wedding - though there were a few pieces saved for the staff."

The cake was commissioned after bride-to-be Sophie Rhys-Jones tasted a sample of the Devil's Food concoction.

It had a 36in base, was 56in high, and took Mrs Fripp's staff a painstaking 515 hours to create. Most of it was made on site at Windsor because of its size.

Mrs Fripp, whose company in Salisbury, Wiltshire, was set up in 1991, has made cakes for dozens of celebrities, including other members of the royal family.
