Preheat the oven to 350°F (175°C) and grease a baking dish.
Unroll the crescent roll dough and separate into triangles.
In a mixing bowl, combine cream cheese, granulated sugar, and vanilla extract until smooth.
Spread the cream cheese mixture onto each crescent roll triangle.
Place a few blueberries on top of the cream cheese mixture on each triangle.
Roll up the triangles starting from the wider end to form rolls.
Place the rolls in the greased baking dish.
In a small bowl, mix melted butter, brown sugar, and cinnamon.
Pour the butter mixture over the rolls in the baking dish.
Bake in the preheated oven for 30 minutes or until the rolls are golden brown.
Serve warm and enjoy!
