Preheat the oven to 375°F (190°C).

In a mixing bowl, combine softened cream cheese, sugar, vanilla extract, and egg until smooth.

Unroll the crescent roll dough and separate it into individual triangles.

Place a spoonful of cheesecake filling at the wide end of each triangle and roll up.

Arrange the rolls on a baking sheet lined with parchment paper.

Brush the tops of the rolls with melted butter, then sprinkle with sugar and cinnamon.

Bake for 15-20 minutes or until golden brown.

Let them cool slightly before serving.
