To make the chocolate truffles: In a small saucepan, heat the cream until hot but not boiling. Pour the cream over the chocolate and allow to melt. Mix well. Refrigerate until use.
For the cake, grease a round silicone cake dish and place a mug in the middle – I used a plastic Tupperware, round, bunt mold.
In a large mixing bowl, combine all the ingredients for the cake and mix on high for about 40 seconds.
Pour the batter into the mold and cook on high for 5 minutes. Check the cake with a tester after cooking time and allow one more minute if not done. Remove on a cake stand to cool.
For the garnishes – melt extra chocolate with a tablespoon of milk and pour over the cake. Add crushed hazelnuts.
For the truffles – use a spoon and scoop balls of ganache and place a hazelnut in the center of each truffle. Dust with cocoa. Arrange on cake.
Recipe Notes
The dark chocolate truffles can be made a few days ahead.
