First, preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. This keeps the pastry from sticking and ensures even baking.
Next, make the cream cheese filling. In a small bowl, stir together the cream cheese, sugar, vanilla, lemon zest, lemon juice, and egg yolk. Mix until it’s smooth, creamy, and slightly thick. Set it aside.
Then, roll out your puff pastry on a lightly floured surface. Use a large star-shaped cookie cutter to cut out as many stars as you can.
With a slightly smaller cutter, gently score a border inside each star. This helps create that signature puffed edge while keeping the filling contained.
Now, spoon about 1 to 1½ tablespoons of the cream cheese mixture into the center of each star. Try not to spread it past the inner border. Add a few fresh raspberries and blueberries on top.
After that, brush the outer edges of each star with the reserved egg white. Sprinkle a little cinnamon sugar around the edges. This adds a lightly sweet crunch and a warm, spiced finish.
Bake for 15 to 18 minutes, or until the pastries are golden, puffed, and crisp. The cream cheese should be just set, and the edges lightly browned.
Finally, let the stars cool slightly. Then place fresh raspberries and blueberries in the center.
Brush the fruit with slightly warmed strawberry glaze for shine, and dust with powdered sugar just before serving.
