Turkish Apple Cinnamon Cookies (Elmalı Kurabiye)

Peel and grate the apples.

Transfer them to a skillet or saucepan, and add the sugar and cinnamon.

Cook the apples, stirring occasionally, until they release their juices and the excess liquid evaporates.

Remove the filling from the heat, stir in the chopped walnuts, and let it cool completely.

Combine the softened butter or margarine, vegetable oil, egg, powdered sugar, baking powder, and vanilla.

Gradually add the flour and knead into a soft dough that doesn't stick to your hands.

Pinch off walnut-sized pieces of dough, shape them, and spoon the apple filling inside.

Arrange the cookies on a baking sheet and bake in a preheated oven at 180°C (350°F) until lightly golden.
