Method
Prepare the Dough: In a medium bowl, mix flour, salt, and baking powder. In a separate large bowl, cream together softened butter and granulated sugar until light and fluffy. Add 1 egg and vanilla extract, mixing until well incorporated. Gradually add the flour mixture and stir until a dough forms. Wrap the dough in plastic wrap and refrigerate for 30 minutes.
Prepare the Apple Filling: In a medium bowl, combine the diced apples, brown sugar, lemon juice, ground cinnamon, and cornstarch. Stir until apples are coated. Let the mixture sit for 10 minutes to allow the flavors to meld.
Preheat the Oven: While the dough and filling are resting, preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Roll and Cut the Dough: On a floured surface, roll out the chilled dough to about 1/8 inch thick. Use a cookie cutter (approximately 3 inches in diameter) to cut out circles from the dough.
Assemble the Cookies: Place a tablespoon of the apple filling in the center of half of the cut-out circles. Gently fold the other half over to create a pocket, and press the edges with a fork to seal them.
Prepare for Baking: In a small bowl, whisk together the egg yolk and milk. Brush the tops of the cookies with this egg wash for a shiny finish.
Bake the Cookies: Place the cookies on the prepared baking sheet and bake in the preheated oven for 15-18 minutes, or until golden brown and puffed.
Cool and Serve: Remove the cookies from the oven and let them cool on a wire rack. If desired, dust with powdered sugar before serving.
