01 - Place a small spoonful of apple mixture and half a caramel candy at the center of each pastry square.
02 - Fold the pastry squares by pinching corners together and sealing the edges, enclosing the filling.
03 - Set filled pouches seam-side down on a parchment-lined baking sheet.
04 - In a small bowl, whisk together the egg and milk. Brush the egg wash over the tops of each pastry bite. Optionally, sprinkle with coarse sugar.
05 - Bake in a preheated oven at 375°F for 16 to 18 minutes until puffy and golden brown.
06 - Allow bites to cool slightly before serving, as the caramel will be hot.
