Opéra

Calling all coffee lovers ❤️, Love is in the air, and it smells like coffee 😋.

Gâteau Opéra is a French cake, made with layers of almond sponge soaked in coffee syrup, layered with ganache and coffee Italian buttercream, topped with a chocolate glaze. Traditionally made with an almond sponge, I used chocolate instead.
This recipe is lengthy, but not difficult. I made the elements, filmed and assembled this gâteau in 2 hrs.
