Preheat your oven to 350°F (175°C).
In a mixing bowl, cream the softened butter and powdered sugar until light and fluffy.
Add the vanilla extract and mix until combined.
Gradually incorporate the flour and salt, mixing until a dough forms.
Shape the dough into a log or flatten it for cookie shapes.
Wrap the dough in plastic wrap and refrigerate for 30 minutes.
Once chilled, slice the dough into desired shapes.
Place the cookies on a baking sheet lined with parchment paper.
Bake for 15-20 minutes or until lightly golden on the edges.
Allow cookies to cool on a wire rack before serving.
