Preheat oven to 375°F and line a baking sheet with parchment paper.
Unroll the crescent roll dough and separate into 8 triangles.
In a bowl, mix cream cheese, powdered sugar, and vanilla until smooth.
Spread the cream cheese mixture evenly over each triangle.
Add a small spoonful of blueberry filling near the wide end of each triangle.
Carefully roll up each triangle and place on the baking sheet.
Sprinkle the tops with sugar.
Bake for 11-13 minutes or until golden brown.
Let cool slightly before serving.
