Preheat the oven to 200 °C.
Roll out the puff pastry and divide into 8 equal squares.
Peel, core and halve the apples and cut into thin slices.
Cover half of the pastry squares with apple leaves, sprinkle with powdered sugar and cinnamon.
Cut the other half at regular intervals with a knife (see photo).
Then brush the edges of the pastry squares with beaten egg and fold them together. Press the edges and brush the outside of the pastry with egg.
Place on a baking tray lined with baking paper and bake for about 20 minutes. Sprinkle with powdered sugar and serve the apple pockets while still warm.
