The best apple turnover you will ever have. Made with a buttery, flaky puff pastry shell that's filled a sweet, tart apple & cinnamon filling and glazed with a cream cheese icing.
Combine the lemon juice and diced apples in a bowl to prevent them from turning brown. Add sugar, cornstarch, cinnamon, nutmeg, salt, and melted butter. Mix to combine. Set aside.
On a floured surface, roll each sheet of puff pastry to a 12-inch by 12-inch (30cm by 30cm) square. Cut each sheet into 4 squares and make sure they stay chilled until you are ready to use them.
Transfer to a cookie sheet lined with parchment paper/grease proof paper. Brush the edges of each square with the egg wash and neatly place 1/3 cup of the apple mixture on half of the square.
Fold the pastry diagonally over the apple mixture and seal by pressing the edges with a fork.
Brush the top with egg wash, make a small slit on the top of each turnover, and bake for 20 minutes, until browned and puffed. Let cool for 5 minutes.
Mix the cream cheese butter, sugar, and vanilla and beat until smooth. Drizzle each turnover with icing. Serve warm.
