Gerbeaud slice is named after the world-famous confectionery, Café Gerbeaud, which is situated at Vörösmarty square 7 in Budapest. It’s one of the greatest and most traditional café-confectioneries in Europe. The legend of Gerbeaud began with Henrik Kugler who was the third child of a confectionery dynasty. He opened his confectionery in 1858 at József Nádor square. This was the first place where ice cream creations were available. In order to be closer to the city center, Kugler in 1870 moved the store to Vörösmarty square. His coffees, liqueurs and sweets attracted the audience, mignons and Kugler cakes had a good market since it was possible to take them home, wrapped on a paper tray.
He met Emil Gerbeaud, the talented young confectioner in Paris in 1882. As there was no successor who could have taken over the leadership of the store, Kugler invited Gerbeaud to Budapest in 1882 to declare him to his business partner. Since 1884 Gerbeaud was the new owner of the confectionery and expanded the selection with numerous products like butter creams, Parisian crèmes, hundreds of kinds of short cakes, candies. He employed 60 persons for sales and service. As a chocolatier Gerbeaud naturalized the cat tongue chocolate and the cognac cherry bonbon in Hungary. By the end of the 19th century, he had about 150 employees, many of whom only came to Budapest to learn and work with Gerbeaud. Gerbeaud became internationally acclaimed. He was awarded numerous national and international prizes. The secret of his success was that he strictly took care of the product quality, mistakes were not allowed.

Let the dough rise for an hour.
Preheat the oven to 180°C.
Bake the cake for approx. 40-45 minutes until the top gets golden brown.

Prepare the chocolate couverture. In a small saucepan warm up the chocolate and the cream until the chocolate melts completely. Remove from the heat and stir in the butter until it is melted. Cool the chocolate couverture slightly until it just starts to thicken but is still pourable. Pour onto the top and cover the whole surface.
Wait until the chocolate sets, then you can cut into small pieces using a sharp knife dipped into hot water.
