Dobos cake

The dobos cake is the most famous Hungarian cake. The inventor of the cake is Jozsef C. Dobos, Hungarian confectioner. According to the legend Dobos' apprentice put sugar instead of salt to the cream when he churned the butter. This accident gave the idea to Dobos Jozsef to create a cake with buttercream. The cake was very new and modern at that time because it was not foamy as the other cakes back then.
In 1885 Dobos introduced his cake in the National General Exhibition of Budapest and soon the cake became very popular through whole Europe. Dobos did not share or sell his recipe, but he developed a container in which the cake could be shipped. He also toured with his cake.
Some confectioners tried to reproduce his cake, but they could not achieve the same result. Finally, when he retired he gave his recipe to the Budapest Confectioner's and Gingerbread Makers' Chamber of Industry. Then the recipe spread out among confectioners and became available for everyone.
The dobos cake stands from layers, chocolate buttercream and caramel topping. It is a quite difficult recipe, so I recommend it for more advanced bakers. Dobos cake worth a try since it was not  accidentally very popular and imitated by so many confectioner in the end of 19th.
