It usually takes no effort at all to polish off a whole box of Jaffa Cakes.
But here’s one you’ll only want to nibble on.
This is the world’s largest Jaffa Cake, measuring four feet in diameter.
It beat the previous record of just under three feet with plenty of chocolate and sponge to spare.
Ms Quinn, the 2013 Bake Off winner, made the humungous cake with the help of staff at the Hambleton Bakery in West Bradford, Nottinghamshire.
The cake contained 6kg of butter, sugar and flour, 3l of marmalade, 9l of orange jelly, 120 eggs and 20kg of dark chocolate.
Luckily, they found a big enough kitchen in which to make it.
Ms Quinn, from Market Harborough, Leicestershire, said she was inspired to bake the delicacy after listening to the ongoing debate over whether Jaffa Cakes are cakes or biscuits.
‘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,’ she said.
‘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.
‘Anyone who wanted orange jelly that day would have had no luck either, as I think we bought the local stores out of it.
‘We also had to drizzle so much chocolate over the top of it.
‘I had worked with Hambleton before and I was really grateful they let me use their kitchen. I wouldn’t have managed it anywhere else.’
Ms Quinn charted the cake’s progress on her Instagram page.
After it was made, the cake was transported by van to a pub in London to be unveiled, a task even more nerve-wracking than baking it.
‘We had to carry it on a giant wooden pallet, and with that it weighed about 60kg,’ said Ms Quinn.
‘We then carefully slid it into a van to get it down to London, covered in plastic wrap.
‘After we’d parked we had to carry it across a busy road and into a pub, which was full of people watching rugby at the time. It was a bit of a nightmare.
‘I almost didn’t fit up the stairs to the room where we were going to unveil it. We had it measured downstairs just in case it broke on its way up.
‘It’s great to get a world record. I think I might try a giant Hobnob next. I can see that working.’
