The Sachertorte consists of a chocolate sponge cake with a thin layer of apricot jam in the middle and dark chocolate icing on the top and sides. The main difference between the cake from the Hotel Sacher and from the Demel bakery is that the Original Sacher Torte has a layer of apricot jam under the icing and in the middle of the cake. The cake from Demel has only jam under the icing.
