Method
Make the filling
- Melt the butter in a 10-inch skillet over medium heat.
- Stir in the apple, brown sugar, cornstarch, cinnamon, and salt until the apple is coated.
- Cook for 8–10 minutes, stirring frequently, until the apple is tender and the juices have thickened.
- Remove from the heat and stir in the caramel sauce.
- Transfer the filling to a bowl and refrigerate for at least 30 minutes, until completely cool.
Assemble and bake
- Heat the oven to 400°F and line an 18x13-inch baking sheet with parchment paper.
- Unfold each puff pastry sheet on a clean work surface and cut it into 4 equal squares.
- Divide the cooled filling evenly among the squares, leaving a 1/2-inch border.
- Fold each square diagonally to form a triangle and press the edges closed with a fork.
- Arrange the turnovers on the baking sheet.
- Brush the tops with the beaten egg.
- Bake for 18–22 minutes, until puffed and deep golden brown.
- Cool on the baking sheet for 10 minutes before serving.
Notes
Keep the puff pastry cold while assembling for the flakiest layers. Store turnovers covered in the refrigerator for up to 3 days; freeze baked turnovers for up to 2 months. For a dairy-free variation, use dairy-free butter, caramel sauce, and puff pastry.
