Opera cake
Opera cake is a French cake. It is made with layers of almond sponge cake soaked in coffee syrup, layered with ganache and coffee French buttercream, and covered in a chocolate glaze.
According to Larousse Gastronomique, "Opéra gâteau is an elaborate almond sponge cake with a coffee and chocolate filling and icing."Origin
The cake was popularized by the French pâtisserie house Dalloyau, but its origin is unclear. One creator-claimant, at Dalloyau in 1955 is Cyriaque Gavillon, grandfather to Christelle Bernardé, current co-president, and named by his wife Andrée Gavillon after the Opéra Garnier.
Gaston Lenôtre also claimed the honour of inventing the dessert in 1960, though an advertisement in Le Gaulois in 1899 offers a "gâteau opéra".
