In a small bowl, mix together soft cream cheese, sugar, and vanilla until smooth and creamy.
Roll out your puff pastry and cut it into even squares.
For some squares, spoon in the cream cheese mixture and top with a mix of fresh raspberries, cranberries, and strawberries.
For others, spread a little Nutella and add cranberries for a rich, chocolatey twist.
Fold or shape each pastry using one of the creative methods (as shown in the video or guide).
Place the shaped pastries onto a baking sheet lined with parchment paper.
In a small bowl, whisk together one egg and a splash of milk. Brush this mixture over the tops of the pastries for a golden, shiny finish.
Bake in a preheated oven at 200°C / 400°F for about 15 minutes, or until puffed and golden brown.
Let cool slightly, then dust with powdered sugar before serving.
