GBBO 2013 winner Frances Quinn has made a 4ft-wide version of a jaffa cake with Hambleton Bakery, which has broken the world record by over a foot.The record-breaking jaffa cake was nearly 23 times the size of the ones you find on supermarket shelves – the recipe included 120 eggs, six kg of butter and three litres of marmalade.Quinn teamed up with Hambleton Bakery for the challenge, at its base in West Bridgford, Nottinghamshire. Last week she announced the launch of a new range to be sold across its shops.She said: “I got the idea when there was a whole debate going on about whether jaffa cakes are biscuits or cakes.It really mattered to me as well, because I make a lot of jaffa cakes and if they were classed as biscuits, there would be more tax on them. But I decided to make the largest-ever one. I really wanted to break the record.It took a lot of planning. We actually had to bake it in six parts and then fit it all together, like a giant jigsaw.”She added that anyone who wanted orange jelly that day would have had no luck either, as she thought the team had bought the local stores out of it.Having baked the giant jaffa cake, Quinn had to transport it to London for its unveiling. She said getting it in and out of the van and then carrying it up a small flight of stairs in a pub was almost more of a challenge than making it.
