Prekmurska gibanica (Prekmurian layer cake) is a type of Slovenian gibanica or layered cake. It contains poppy seeds, walnuts, apples, raisins and ricotta fillings. Although native to Prekmurje, it has achieved the status of a national specialty of Slovenia. The unique sweetmeat shows the variety of agriculture in this region. The name gibanica comes from dialectical expression güba and in this case refers to a fold.
For centuries prekmurska gibanica was served as a festive and ritual dish in Prekmurje. The exact origin of the recipe is not clear. Early sources suggest that it evolved over centuries. The oldest extant document (1828) by József Kossics described the wedding (Prekmurian dialect: Gostüvanje) never goes by without gibanica, which is done as follows: "The dough is rolled until thin, sprinkled with grated cabbage, turnips or ricotta. All is covered by second layer of dough. It is sprinkled as previously. 10 or 11 such layers are thus composed and form a conspicuous cake."
Prekmurje (Slovene pronunciation: [prɛkˈmúːrjɛ];dialectically: Prèkmürsko or Prèkmüre; Hungarian: Muravidék) is a geographically, linguistically, culturally and ethnically defined region settled by Slovenes and lying between the Mur River in Slovenia and the Rába Valley (the watershed of the Rába) (Slovene: Porabje) in the most western part of Hungary. It maintains certain specific linguistic, cultural and religious features that differentiate it from other Slovenian traditional regions.
It is named after the Mur river, which separates it from the rest of Slovenia (a literal translation from Slovene would be Over-Mur or Transmurania). In Hungarian, the region is known as Muravidék, and in German as Übermurgebiet.
