Preheat oven to 350°F (175°C). Lightly grease a 13x9-inch baking dish. Unroll one crescent roll can. Press seams together and lay it flat in the dish.
Beat cream cheese, sugar, vanilla, and egg until smooth and lump-free. Evenly spread the cream cheese mixture over the crescent base.
Unroll the second crescent sheet, seal seams, and place over the filling.
Brush the top with egg white for a golden, glossy finish.
Bake 35–45 minutes until puffed and golden. Cover edges with foil if browning too fast.
Whisk powdered sugar, milk, and vanilla until smooth and pourable.
Cool for 20 minutes, then drizzle glaze evenly over the top.
Cut and serve warm or at room temp—perfect with coffee or tea!
