We've already had cronuts and cruffins, so it was only a matter of time before another croissant hybrid was born. This one doesn't have a silly name, either. Three words:birthday cake croissants. Two more words: yes please. This breakfast of champions has been invented by Thiago Silva. No, not the Brazilian footballer, the pastry chef at the recently opened Union Fare restaurant in New York. The croissant batter is mixed with rainbow sprinkles and, once baked, filled with cream and topped with pink 'fairy dust' made from more ground sprinkles. Because it's not a real party without sprinkles. But until this sweet treat makes its way across the Pond, the closest thing we'll get to a birthday cake croissant is a regular croissant stuffed with a slice of birthday cake. Which actually also sounds pretty great.
