Pastelitos de queso were a staple of my Cuban childhood, from Saturday morning bakery runs to birthday parties where they showed up by the dozens! My homemade version pairs flaky puff pastry with a sweet cream cheese filling, then gets brushed with egg wash and baked at 400°F until puffed and golden. Using store-bought puff pastry keeps them simple enough to make whenever a craving hits.
Preheat oven to 400ºF. Line a baking sheet with parchment paper. Cut each pastry sheet into 9 squares (4x4) and place them on the baking sheet.
Carefully spread one tablespoon of the softened cream cheese, diagonally, from the left corner of the square to the bottom right corner of the square.
Brush the corners with egg wash. Bring the bottom left corner of the pastry over the cream cheese and connect to the top right corner, pressing down gently to seal. Repeat with all the pastry squares.
Brush each pastry square with egg wash and sprinkle evenly with the granulated sugar.
Place the pastries on a parchment paper-lined baking sheet. Bake for 15-20 minutes. Serve and enjoy!
