Chimney cake, also known as kürtőskalács, is a sweet pastry that originated in Hungary. It is made by wrapping dough around a cylindrical spit, then baking it over an open fire. The result is a crispy, caramelized exterior and a soft, fluffy interior. Chimney cake is often coated in sugar and can be filled with various fillings such as Nutella, cinnamon, or vanilla cream.
