Don't let the appearance fool you. This is not what it seems: it is a cake, created in the mould of an Easter egg. Playing with the theme of the Black Forest cake, Marc Ducobu created layers of dark chocolate sponge and an elegant chocolate mousse - made with Single Origin chocolate Madagascar for its intense taste and fruity notes. Whipped cream creates lightness and counterbalances the intensity. This recipe is assembled upside down (or 'à l'envers' as the French call it).
