Apple strudel is a classic Austrian dessert made with layers of phyllo dough and a filling of thinly sliced apples, sugar, cinnamon, and raisins. The phyllo dough is brushed with melted butter and layered with the apple filling, then rolled up and baked until golden and crispy. The result is a sweet and tart dessert with a flaky and delicate pastry. Apple strudel is often served warm, dusted with powdered sugar, and accompanied by a scoop of vanilla ice cream or a dollop of whipped cream.
