My friend asked me for the most ridiculously chocolaty cake I have every made for her 30th birthday. So here it is!! 4 layers of chocolate fudge cake, filled with (from the bottom up) chocolate hazelnut mousse & whole roasted hazelnuts, dark chocolate ganache, and another layer of the mousse and hazelnuts. It is covered in dark chocolate ganache and piped with mousse stars & hazelnuts. The whole cake is surrounded by Pirouline cookies, wrapped in a bow. THe plaque is molding wafers and ganche.
