Instructions
Preheat the oven to 400°F and line two baking sheets with parchment paper.
In a small saucepan, cook the diced apples with butter, sugar, cinnamon, and salt over medium-low heat until tender and juicy, about 5–10 minutes. Set aside to cool slightly.
Unfold the puff pastry sheets on a lightly floured surface. Cut each sheet into four equal squares to make 8 turnovers total.
Place a spoonful of apple filling in the center of each square, draining off any excess liquid.
In a small bowl, whisk together the egg and water. Brush along the edges of each pastry square.
Fold each square diagonally into a triangle, pressing edges to seal, then crimp with a fork.
Cut a few small slits on top of each turnover to allow steam to escape. Brush tops with the remaining egg wash.
Place the assembled turnovers on the prepared baking sheet and refrigerate for 15–20 minutes before baking. Chilling helps firm up the butter in the puff pastry, creating flaky, golden layers in the oven.
Bake for 20–22 minutes, or until puffed and golden brown. Cool slightly on a wire rack.
For the glaze, whisk together powdered sugar and heavy cream in a small bowl until smooth. Drizzle over turnovers before serving.

Notes
Tips
Keep puff pastry cold until ready to use so it bakes up light and flaky.
Peel and dice apples into small, even pieces so the filling cooks evenly.
Chill assembled turnovers before baking to help seal edges and create flaky layers.
Storage & Make Ahead
Store baked turnovers in an airtight container in the refrigerator for up to 3 days.
Freeze baked turnovers once cooled for up to 2 months; reheat in a 350°F oven until crisp.
Assemble turnovers up to 4 hours ahead, refrigerate, and bake when ready.
