Set your oven to 200°C (400°F). Place parchment paper on two baking trays, and position the racks in the top and bottom thirds of the oven.
02 -
Mix the softened cream cheese, sugar, vanilla extract, and egg yolk in a bowl. Use a handheld mixer or fork until it’s smooth and lump-free. If the cheese is still firm, microwave it for about 20 seconds to soften.
03 -
Combine the fresh blueberries with blueberry jam in a bowl until they’re well coated and mixed together evenly.
04 -
Lay the thawed pastry sheets on a surface dusted with flour. Cut nine equal-sized rectangles (3x3 grid) from each sheet using a pizza cutter or knife.
05 -
Score a smaller rectangle inside each piece, about 1/3 inch away from the edges. This helps the sides puff up. Brush the border with the whisked egg.
06 -
Spoon 1 1/2 tablespoons of the cheese mixture into the center of every pastry piece, spreading it just up to the scored border without spilling over.
07 -
Drop the blueberry mixture gently over the cheese layer. Optional: sprinkle sugar along the edges for extra sweetness and crunch.
08 -
Transfer the finished pastry pieces onto the baking trays with parchment. Leave around 2 inches (5 cm) between them so they have enough room to rise.
09 -
Pop the trays into the preheated oven and bake for 13–15 minutes. Halfway through, switch the trays’ positions to ensure even baking. The pastries are ready when the edges are golden and puffed up.
10 -
Let the pastries sit for a few minutes to cool off. Garnish with some lemon zest if you like, then enjoy while they’re still warm.
