Apple Cookies

For the filling, grate the apples and sauté them with sugar in a skillet until the juices evaporate, then stir in the cinnamon and optional walnuts at the end, and let cool.

For the dough, whisk together the butter, vegetable oil, powdered sugar, egg, yogurt, and wheat starch in a bowl until smooth.

Add the vanilla and baking powder, then gradually incorporate the flour to knead a soft, slightly pliable dough.

Divide the dough into small portions, roll each out into a small circle, place a spoonful of the apple filling in the center, and seal the edges.

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