Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a mixing bowl, cream together the butter, cream cheese, and sugar until light and fluffy.

Add vanilla extract and mix until combined.

Gradually add the flour and salt, mixing until a soft dough forms.

Roll the dough into small balls and place them on the prepared baking sheet.

Flatten each ball slightly with your fingers or the back of a spoon.

Bake for 12-15 minutes or until the edges are lightly golden.
