Instructions

Add the blueberries, sugar, and lemon juice to a saucepan over medium heat. Simmer for 15 to 20 minutes until the sauce thickens, then set aside to cool completely.
Preheat the oven to 425°F and line a baking sheet with parchment paper.
Roll the puff pastry into a rectangle if needed and cut it into 6 equal squares.
Sprinkle each square lightly with sugar, fold into triangles, and gently seal the edges with your fingers or a fork.
Whisk the egg and milk together to make an egg wash. Brush the tops of the pastries with the mixture and sprinkle with additional sugar.
Bake for 20 to 22 minutes until puffed and deeply golden brown. Let the pastries cool completely.
Whip the heavy cream until stiff peaks form. In a separate bowl, mix the mascarpone cheese, vanilla extract, and powdered sugar until smooth.
Gently fold the mascarpone mixture into the whipped cream and transfer the filling to a piping bag.
Partially slice open each cooled pastry, spoon in blueberry sauce, pipe in the mascarpone whipped cream, and dust with powdered sugar before serving.

Notes

Frozen blueberries can be used for the sauce; simmer a few extra minutes if needed.

Prepare the pastry shells, blueberry sauce, and mascarpone cream ahead of time and assemble just before serving.

Cream cheese can be substituted for mascarpone for a slightly tangier flavor.

Store pastry shells separately at room temperature for up to 2 days to keep them crisp.

Refrigerate the blueberry sauce and mascarpone cream in separate airtight containers for up to 3 days.

Add lemon zest, white chocolate drizzle, or chopped nuts for extra flavor and texture.
