What do you get if you mix 160 eggs, 8kg of dark chocolate and 15kg of orange jelly? The world's largest-ever Jaffa Cake, of course.
The tasty feat was accomplished by former Great British Bake Off winner Frances Quinn alongside McVitie's staff using the company's top secret recipe.
The giant cake - and yes, Jaffa Cakes are cakes - was the equivalent of 6,557 regular-sized Jaffa Cakes and measured 175cm in diameter.
Ms Quinn baked the 80kg creation in celebration of the 15th anniversary of the Britain's Got Talent programme.
She said: "It was an absolute pleasure to partner with McVitie's to beat the record I set five years ago, it was great to celebrate the 15th birthday of Britain's Got Talent with such an iconic cake.
"I hope audiences watching the show at the live semi-finals enjoyed tucking in and celebrating the contestants this year."
Ms Quinn, who won the fourth series of The Great British Bake Off in 2013, broke her own Guinness World Record set in 2017 with the feat.
The baker worked alongside product development specialist Will McMath and the McVitie's team to tackle the process, which took over 11 hours from start to finish at the McVitie's innovation bakery in High Wycombe, Buckinghamshire.
The Jaffa Cake was served to guests and crew at the Britain's Got Talent live semi-finals outside the Eventim Apollo in Hammersmith, west London, with 300 servings.
David Titman, marketing director of McVitie's, added: "Frances wowed us in 2013 on The Great British Bake Off, and we've been looking forward to working with her ever since to recreate the giant Jaffa Cake using our famous but secret McVitie's recipe."
