Flourless Nutella Cake

Directions

1. 1
   To make the cake:
2. 2
   Beat the egg whites and salt until it forms stiff peaks, around 2 minutes or so. Beat Nutella and softened butter in a different bowl until combined. Add the rest of the ingredients (including the egg yolks) except melted chocolate and the egg whites.
3. 3
   Once everything is well mixed, stir the melted chocolate in and fold the egg whites into the mixture gently.
4. 4
   Pour the batter into a 9-inch springform pan (lined with parchment paper and greased) and cook in a preheated 350°F oven for about 45 minutes. When the cake is done, you will see that the cake will separate from the pan.
5. 5
   Unmold, cool the cake and get the icing ready.
6. 6
   To make the icing:
7. 7
   Mix the heavy cream, chocolate and your choice of liquid (rum or water) in a pan on the stovetop. Heat on moderate setting until the chocolate melts.
8. 8
   Turn off the stove as soon as the chocolate melts, and start whisking until the mixture thickens. (I added 4 tablespoons powdered sugar at this point because it was too dark for me. It still did not end up all that sweet.)
9. 9
   Spread/pour the thickened chocolate mixture over the cake. Decorate with chopped toasted hazelnuts or raspberries.
