Chimney cake, also known as kürtőskalács, is a traditional Hungarian pastry that is popular in Central Europe. It is made from a sweet, yeast-based dough that is rolled into a spiral shape and wrapped around a cylindrical baking spit. The dough is then baked over an open flame or in an oven, resulting in a crispy outer layer and a soft, fluffy interior. Once baked, chimney cake is often coated with sugar, cinnamon, or nuts, giving it a delightful flavor and texture. It is typically served warm and can be filled with various toppings, such as whipped cream or chocolate, making it a popular street food at fairs and festivals.
