In a large bowl, beat the softened butter and powdered sugar together until light and fluffy. Add the vanilla extract and mix until combined.
Gradually mix in the flour and salt. The dough will be soft but not sticky. Don’t overmix—just blend until everything is incorporated.
Form the dough into a disc or log, wrap it in plastic wrap, and chill in the refrigerator for 30 minutes. Once chilled, roll out the dough to about ½ inch thick and cut into desired shapes using a cookie cutter or knife.
Place the cookies on a parchment-lined baking sheet and bake in a preheated oven at 325°F (160°C) for 20–25 minutes or until the edges are lightly golden. Cool on the tray for 5 minutes, then transfer to a wire rack.
