Apple strudel is a traditional Austrian dessert made with layers of phyllo dough and a filling of spiced apples, raisins, and nuts. The phyllo dough is rolled around the apple filling, creating a long, thin pastry. After baking, the apple strudel is dusted with powdered sugar and served warm. The combination of the crispy phyllo dough and the sweet, tart apple filling makes for a delicious and comforting dessert. Apple strudel is often enjoyed during the fall and winter months.
