In a mixing bowl, combine softened cream cheese, powdered sugar, cocoa powder, and vanilla extract. Mix until smooth and creamy.

Fold in the chocolate chips gently.

Preheat the oven to 375°F (190°C).

Roll out the puff pastry on a lightly floured surface into a rectangle.

Cut the pastry into four equal squares.

Place a generous spoonful of the filling in the center of each square.

Fold the corners of the pastry over the filling to create a diamond shape and pinch to seal.

Place the assembled danishes on a baking sheet lined with parchment paper.

Brush the tops with the beaten egg wash and sprinkle with granulated sugar.

Bake in the preheated oven for 20-25 minutes or until golden brown.

Remove from the oven and let cool slightly before serving.
