Preheat the oven to 400°F (200°C). Line two baking sheets with parchment paper. Puree the blackberries until smooth. Strain through a fine-mesh sieve to remove seeds and discard the seeds. Transfer the strained blackberry puree to a medium saucepan, heat over medium, and simmer until reduced to ½ cup, about 20 minutes, stirring occasionally. Remove from heat and cool slightly. Whisk together the reduced blackberry puree, sugar, whole egg, egg yolks, and lemon juice. Heat the mixture over medium-low while stirring constantly. Simmer until thickened, about 5 minutes. Remove from heat and whisk in the butter until melted. Strain the curd again for a silky texture. Cool and set aside.

Lightly dust a clean surface with flour. Roll out the puff pastry sheets slightly for even thickness. Use a round cutter to cut 3 rows of 3½-inch circles per sheet, making 18 total. Place the pastry rounds on the prepared baking sheets, spaced apart.

Prick the center of each pastry round with a fork to prevent excessive puffing. Add about 1 tablespoon of cream cheese filling to the center of each round, leaving a border. Brush the edges with egg wash and sprinkle 1 teaspoon of turbinado sugar on the edges for extra caramelization.

Bake in the preheated oven for 15–18 minutes, until golden brown and puffed. Rotate the baking sheets halfway through for even baking. Cool the pastries completely before filling them.

Spoon about 1 heaping tablespoon of the blackberry curd into the center of each cooled pastry. Top with fresh blackberries and lightly dust with powdered sugar.
