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

In a large mixing bowl, cream together 1 cup of softened unsalted butter and 1/2 cup of granulated sugar for 3-5 minutes until light and fluffy.

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

Gradually incorporate 2 cups of all-purpose flour until the dough forms a soft consistency, avoiding overmixing.

Shape the dough into a log about 2 inches in diameter, wrap in plastic wrap, and refrigerate for at least 1 hour.

Once chilled, slice the log into 1/4-inch thick rounds and arrange on the prepared baking sheet.

Lightly sprinkle each cookie with flaky sea salt before baking.

Bake for 12-15 minutes until the edges are golden brown and the centers are pale.

Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
