Opera Cake is a classic French dessert known for its rich, layered structure and harmonious flavors. It typically consists of thin layers of almond sponge cake (called Joconde), soaked in coffee syrup, layered with coffee-flavored buttercream and chocolate ganache. The cake is topped with a shiny chocolate glaze, giving it an elegant, polished finish.

The combination of coffee, chocolate, and almond creates a sophisticated balance of bitter, sweet, and nutty notes. Opera Cake is usually served in rectangular slices to showcase its beautiful layers.
