Gateau Opera

Description

This layered gateau is a much loved classic with its layers of coffee soaked genoise (light almond spong cake), fluffly coffee crème mousseline (light buttercream), and dark chocolate ganache. The cake was popularized by the French pâtisserie house Dalloyau, but its origin is unclear. Cyriaque Gavillon claimed to have created the cake there in 1955 and that his wife Andrée named it after the Opera Garnier.
