Preheat oven to 375 degrees.
Combine the cream cheese, vanilla, and powdered sugar in a
mixing bowl and beat until thoroughly combined and smooth.
Unroll crescent roll dough and separate into 8 triangles along the
perforated seams. Place one triangle of dough in front of you with
the short flat side facing you. Spread about a tablespoon of the
cream cheese mixture across the bottom third of the dough
triangle. Top the cream cheese with two rows of blueberries.
Starting with the edge closest to you, roll the dough forward all
the way to the far tip of the triangle, surrounding the blueberries.
Place on a baking sheet and repeat with remaining ingredients.
Bake for 10-13 minutes until the rolls are golden and serve.
