Preheat oven to 400°F (200°C). Line two large cookie sheets or baking trays with parchment paper. Arrange oven racks in the upper and lower thirds of the oven.

In a small bowl, combine cream cheese, icing sugar, egg yolk, and vanilla extract. Mix thoroughly using a fork or handheld mixer until smooth. If cream cheese is not softened, microwave it for 15–30 seconds to avoid lumps.
03 -
In another small bowl, mix blueberries and blueberry jam until evenly combined.
04 -
Unroll thawed puff pastry sheets on a lightly floured surface. Using a knife or pizza cutter, cut each sheet into 9 evenly sized rectangles (3x3 grid).
05 -
Lightly score a smaller rectangle within each piece, leaving a 1 cm (1/3 inch) border. This helps the edges puff during baking. Brush the outer edges with egg wash.
06 -
Spoon approximately 1 1/2 tablespoons of the cheese mixture into the center of each pastry. Spread evenly up to the scored edges, leaving the borders clean.
07 -
Layer the blueberry mixture on top of the cheese filling. Optionally, sprinkle granulated sugar around the edges for extra texture and sweetness.
08 -
Place prepared pastries onto the lined baking trays, spacing them about 5 centimeters (2 inches) apart to allow for expansion.
09 -
Bake in the preheated oven for 13–15 minutes, switching the trays' positions halfway through. Bake until the edges puff and turn golden brown.

Allow pastries to cool slightly before serving. Optionally, garnish with lemon zest. Serve warm and enjoy!
