Heat your oven to 375°F and line a baking sheet with parchment paper. On a floured surface, cut your puff pastry into 6 equal rectangles.
02 -
Beat together your softened cream cheese, sugar, vanilla, and lemon zest if using, until it's nice and smooth.
03 -
Spread some cream cheese mix in the middle of each pastry rectangle. Top with blueberries (tossed in flour if frozen). Fold the edges in slightly to make a border.

Whisk egg and milk together, then brush it on the pastry edges so they'll turn golden brown in the oven.
05 -
Bake for 15-20 minutes until they're puffed up and golden brown. Let them cool a bit.
06 -
Mix powdered sugar, milk, and vanilla until smooth. Drizzle this sweet glaze over your slightly cooled pastries.
