What’s the hybrid? A muffin and a doughnut that often comes filled with jam, chocolate, custard and other popular sweet injections.
Where can I get one? London-based purists can find the original at Bea’s of Bloomsbury tearooms in St Paul’s, Farringdon and its namesake.
Event says: This innocent-looking treat has provoked some heavy legal issues. London tearoom Bea’s of Bloomsbury claims itself as the creator, although Starbucks’ factory supplier trademarked the name in late 2013.
The high street chain has since stopped selling the Duffin.
What’s the hybrid? A croissant stuffed with cookies – specifically, Double Stuffed Oreos.
Where can I get one? Toronto's Clafouti Patisserie et Café avoided poor Bea’s of Bloomsbury’s misery and cleverly trademarked the Crookie when it devised the invention.

What's the hybrid? We'd love it to mean a brownie doughnut, but alas it is a brioche doughnut.
Where can I get one? A surprising number of places around London: The Hole in Hackney, St John Bakery and Asia de Cuba all serve them. As an un-trademarked hybrid, there's also a plethora of recipes online so you can create your own.
Event says: It's a subtle mix, but who would say no?
What’s the hybrid? It’s probably the most outlandish of all the bakery crossovers: cherry, pumpkin and apple pies baked inside cake and stacked together.
Where can I get one? In your kitchen. Charles Phoenix, author and self-proclaimed ‘ambassador of Americana’ developed this culinary monster – you can learn how to create your own from the video above.
Event says: Five stars for creativity – a centerpiece that will baffle and bemuse guests in equal measure.
