There are many stories about the origins of this cake, known as both Clichy cake and Opéra cake. Many believe that Louis Clichy was its creator because he premiered the gâteau, with his name written across the top, at the 1903 Exposition Culinaire in Paris. It became the signature cake of Clichy's shop on the Boulevard Beaumarchais. However, another pastry shop, Dalloyau, sold a very similar dessert, known as L'Opéra (in honor of the Paris Opera), and some claim that theirs was the original.
