Three decadent layers of ultra-moist chocolate sponge, dark chocolate ganache filling, and a fluffy whipped chocolate frosting make this the ultimate celebration cake. It looks impressive but follows straightforward steps anyone can master.

Chef's Notes
The coffee doesn't make the cake taste like coffee β it intensifies the chocolate flavour dramatically.
Make sure all refrigerated ingredients are at room temperature before mixing for the best texture.
The cake keeps refrigerated for up to 4 days. Bring to room temperature before serving.
