# What You’ll Need:
→ Pastry
01 - 2 sheets puff pastry (approximately 17.6 ounces, thawed if frozen)
02 - 1 large egg (for egg wash)
03 - 1 tablespoon milk
→ Apple Filling
04 - 3 medium golden apples, peeled, cored, and diced
05 - 2 tablespoons unsalted butter
06 - 1/4 cup granulated sugar
07 - 2 tablespoons brown sugar
08 - 1 teaspoon ground cinnamon
09 - 1/4 teaspoon ground nutmeg
10 - 1/2 teaspoon pure vanilla extract
11 - 1 tablespoon lemon juice
12 - 1 tablespoon cornstarch
→ Optional Topping
13 - 2 tablespoons coarse sugar for sprinkling
# Directions:
01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - In a medium skillet over medium heat, melt the butter. Add diced apples, granulated sugar, brown sugar, cinnamon, nutmeg, and lemon juice. Cook, stirring frequently, for 4 to 5 minutes until apples soften.
03 - Stir in vanilla extract and cornstarch. Cook for 1 to 2 more minutes until the mixture thickens slightly. Remove from heat and let cool.
04 - On a lightly floured surface, roll out puff pastry sheets if needed. Cut each sheet into 4 equal squares, yielding 8 squares total.
05 - Place a generous spoonful of the cooled apple filling in the center of each pastry square. Fold each square into a triangle and press edges together to seal, then crimp with a fork.
06 - Arrange turnovers on the prepared baking sheet. Whisk together egg and milk, then brush the mixture evenly over the turnovers. Optionally, sprinkle coarse sugar over the top.
07 - Using a sharp knife, make a small slit on the top of each turnover to allow steam to escape during baking.
08 - Bake in the preheated oven for 20 to 25 minutes, until golden brown and puffed.
09 - Transfer turnovers to a wire rack and allow to cool for 10 minutes before serving.
