Lightly flour the rolling pin and the puff pastry dough.
Roll out puff pastry dough on a lightly floured surface 1/8t inch (3mm) thick. This thickness ensures the pastry is crisp and flaky while still being sturdy enough to hold the filling.
Keep the dough in a rectangle shape and cold during the process.
Cut out 12 discs that are 3 inches wide with the help of a cookie cutter and transfer them to a baking tray lined with baking paper.
Spoon the apple filling (2 tablespoons) on 6 discs leaving some space around the edges.
Brush milk around the edges and cover the top with the remaining 6 discs of dough.
Use a fork to press and seal the edges and make sure the edges are sealed.
Cut 3 tiny slits on the top with a knife for steam to escape.
Brush the tops lightly with maple syrup. Sprinkle turbinado sugar/cane sugar.
Bake in a preheated oven at 375f (190C) for 15-17 minutes until they’re golden brown. Enjoy
