Preheat the oven to 375°F (190°C) and prepare a baking sheet.
In a mixing bowl, combine the softened cream cheese, granulated sugar, vanilla extract, lemon juice, and lemon zest.
Unroll the crescent roll dough and separate it into individual triangles on a clean surface.
Spoon a generous amount of the cream cheese mixture onto the wide end of each triangle.
Roll up each triangle from the wide end to the point, pinching the sides to seal the filling inside.
Place the rolls on the prepared baking sheet and bake in the preheated oven for 12-15 minutes, or until golden brown.
Remove from the oven and let cool for a few minutes before dusting with powdered sugar.
