Preheat the oven to 375°F (190°C), gathering ingredients and equipment.

In a medium bowl, combine 8 ounces of softened cream cheese, 1/4 cup of granulated sugar, and 1/2 cup of melted chocolate, blending until smooth.

Roll out thawed puff pastry to a rectangle, about 1/4 inch thick, and slice into rectangles of 4x6 inches.

Place a spoonful of the cream cheese mixture onto the center of each pastry rectangle.

Fold the corners of each pastry toward the center and pinch edges to seal, brushing the top with egg wash or milk.

Place pastries on a baking sheet and bake for 25 minutes until golden brown.

Let cool on a wire rack for about 5 minutes before serving.
