Beat softened butter and sugar until light and fluffy (~3 minutes). Add vanilla and mix.
Gradually fold in sifted flour and salt until just combined (avoid overmixing).
Option 1: Roll dough into a log, chill for 30 minutes, then slice into rounds.
Option 2: Use a piping bag to create swirls or cookie cutters for shapes.
Preheat oven to 350°F (180°C). Arrange cookies on a lined baking sheet and bake for 10–12 minutes until edges are golden.
Let cookies rest on the sheet for 5 minutes, then transfer to a wire rack.
