Preheat the oven to 190°C (375°F). Line a baking sheet with parchment paper.
02 -
Cut the puff pastry sheet into 6 squares (12x12 cm each). Optionally, cut a small strip from the sheet to create decorative ‘leaves.’ Chill the pastry until ready to assemble.
03 -
Peel the apples. Using a small paring knife and a teaspoon, core the apples but keep the bottom intact to hold the filling.
04 -
Stuff the apple centers with chopped walnuts and chocolate hazelnut spread. Sprinkle extra walnuts on top until the centers are full.
05 -
Place each apple on a puff pastry square, sprinkle with cinnamon, and wrap the pastry around the apple. Pinch the edges at the top to seal. Leave small holes if necessary. Place the wrapped apples on the prepared baking sheet.
06 -
Optionally, use the reserved puff pastry strip to cut out small decorative leaves and attach them to the apples. Beat the egg with 1 tablespoon of milk or water and brush the pastries with the egg wash.
07 -
Bake for 45 minutes or until the pastry is golden brown.
08 -
Let the pastries stand for 5 minutes to cool slightly. Dust with powdered sugar and serve with whipped cream. Enjoy!
