Scottish 24-hour business Clark’s Bakery has claimed to have made the biggest-ever Dundee cake – weighing 26lb and with a diameter of 18 inches.

The cake was commissioned for a Dundee-themed art charity exhibition at Jordanstone College of Art and Design.

Alan Clark, owner of Clark’s Bakery, told British Baker he wanted to bake the cake as it was a challenge.

“The biggest cake we normally do is 12 inches, so I thought this would be a good challenge for me,” he said. “It was difficult to bake as the outside gets baked first and the inside takes much longer.”

The Dundee cake, which is a sultana base-mix with caramel flavouring, took around six-and-a-half hours to bake in total. Seville oranges gives the cake its primary flavour.

The modern-day take on Dundee cake originated in the City of Discovery in the 19th century. It was first popularised when the Keiller’s marmalade company put it into mass production and is said to be one of the Queen’s favourite sweet treats. It is thought the recipe for the Dundee cake was invented for Mary Queen of Scots.

Clark added that he would make the cake again, if a customer requested it. He estimated that the price to produce the cake would be over £100.
