One of the things I like the most about summery, fruity cakes is how fragrant they are. Of course they can be made at any point during the year, but really nothing can mimic the sweet scent of fresh, ripe fruit. This lovely little cake is a perfect mix of fresh berries, chocolate, and hazelnuts. It all starts with a soft Mascarpone and toasted hazelnut base, followed by a layer of smooth white chocolate ganache, a layer of luscious raspberry jelly, and finally, everything is crowned by a layer of extra dark chocolate ganache.
