Krempita

A cremeschnitte , also known as vanilla slice or custard slice, is a custard and chantilly cream cream cake dessert commonly associated with the former Austro-Hungarian Monarchy. However, its exact origin is unknown. This dish remains popular across Central Europe and the Balkans in various variations, all of which include a puff pastry base and custard cream. Vanilla slice emerged as a variety of one of these similar desserts, but it is unknown which variety or varieties evolved into the modern dish. In Slovenia, kremna rezina is commonly associated with the town of Bled, an Alpine tourist destination in northwestern Slovenia. The cake recipe was brought to the local Hotel Park in 1953 by Ištvan Lukačević, chef of the hotel's confectionery store. He came to Bled from Serbia (Vojvodina) where a similar cake was already known. As of October 2009, 10 million cream cakes have been baked at the hotel's patisserie since its invention. The name of the dessert means simply "cream slice". Locals refer to it as kremšnita, from the German word Cremeschnitte, with the same meaning. While the kremna rezina from Bled celebrated their 10th million piece production, Slaščičarna Lenček, which is located in Domžale, in year 2013 celebrated the 75th anniversary since they have made their first one which is called Lenčkova kremna rezina.
