A Gugelhupf (also Kugelhupf, Guglhupf, Gugelhopf, and, in France, kouglof, kougelhof, or kougelhopf) is a light, yeasted marble cake, traditionally baked in a distinctive circular Bundt mold. It is popular in a wide region of Europe, including southern Germany, Austria, Switzerland, Poland and Alsace.
In late Medieval Austria, a Gugelhupf was served at major community events such as weddings, and was decorated with flowers, leaves, candles, and seasonal fruits. The name persisted through the Austro-Hungarian Empire, eventually becoming standardized in Viennese cookbooks as a refined, rich cake, flavored with rosewater and almond. Many regional variations exist, testifying to the widespread popularity of the Gugelhupf tradition.
The Gugelhupf was the sweet chosen to represent Austria in the Café Europe initiative of the Austrian presidency of the European Union, on Europe Day 2006.
