This Chocolate Hazelnut Torte is a European style cake. It is rustic looking, with its thin top crust which is cracked and broken and sunken in the middle. Yet inside the texture of this cake is dense, yet wonderfully soft and moist. It’s buttery rich with the flavors of chocolate and hazelnuts. It really doesn’t need a frosting, and oftentimes I like to serve it with a dollop of whipped cream or crème fraiche.
