Black Forest Cake or Schwarzwalder Krischtorte (German) is a cake name after the specialty liqueur, made from tart cherries when added to the cake gives the cake its distinctive cherry and alcoholic flavor.
Typically this cake consists of several layers of chocolate genoise. These layers are heavily brushed with a combination of cherry liqueur and simple syrup. Then whipped cream mixed with tart cherries is filled between each layer. The cake is frosted with more whipped cream and maraschino cherries and chocolate shavings are used to decorate the cake.
I adapted this recipe from The Cake Bible, called the Swiss Black Forest Cake. The chocolate shavings were made by melting chocolate over double boiler and then spreading it very thinly on a cold marble slab. Using a dough scrapper, scrap the chocolate at an angle to create scrolls.
