In a large mixing bowl, cream together 1 cup of softened unsalted butter and 2/3 cup of granulated sugar until light and fluffy, about 3-4 minutes.

Add in 1 teaspoon of pure vanilla extract and mix until well combined.

Gradually sift in 2 cups of all-purpose flour along with a pinch of salt, then mix until just blended.

Shape the dough into a log about 2 inches in diameter, wrap tightly in parchment paper and chill in the refrigerator for at least 30 minutes.

Preheat your oven to 350°F (175°C) while the dough chills.

Slice the chilled dough into 1/4 inch thick rounds, arrange on a baking sheet and bake for 10-12 minutes.

Allow the cookies to cool on the baking sheet for about 5 minutes before transferring to a wire rack to cool completely.
