Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.
Open the can of crescent rolls and unroll the dough, separating it into 8 triangles on a clean surface.
In a medium bowl, blend the cream cheese, sugar, and vanilla extract until the mixture is creamy and smooth.
Spoon a generous tablespoon of the cream cheese mixture onto the wider end of each dough triangle.
Carefully roll up the dough starting at the wide end and moving towards the point to form a roll, ensuring the filling stays inside.
Place each roll on your prepared baking sheet and bake in the preheated oven for 12-14 minutes, or until the rolls are golden brown and puffed up.
Allow the rolls to cool on the pan for about 5 minutes, then top each one with a spoonful of blueberry preserves.
Serve warm or at room temperature and enjoy!
