Jaffa Cake Biscuit, cake, or a doughnut? Is a Jaffa Cake a biscuit or a cake? It’s a conundrum we’re not sure will ever get solved (it’s a biscuit cake, okay?!). And now there’s a new one to ponder: is a Jaffa Jonut a doughnut or a cake? Let us explain. McVitie’s has unveiled its new Jaffa Jonuts – basically a big ol’ Jaffa Cake with a hole in it. They feature layers of dark chocolate, sponge and the famous tangy orange flavoured filling, now in a doughnut-shaped ring. No, this isn’t a joke. You’ll actually be able to buy the jonuts yourself – either as an individually wrapped ring or in a box of four – in Tesco from May 16.
