This cake is Hungarian in origin, but it’s also popular in parts of northern Serbia that were under Austro-Hungarian rule until the turn of the twentieth century. It’s commonly called Madjarska Palacinka Torta or Hungarian Pancake Torte. Our mothers and grandmothers would typically bake it for Sunday lunch because it’s so quick to make. The layers are somewhere between a pancake and a crêpe, and are sandwiched with various fillings. Almost always, there are walnuts, the most popular nut in the western Balkans. As my aunt used to say: “It isn’t a cake if it doesn’t have walnuts.”
