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

In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.

Add the egg and vanilla extract to the mixture, beating until well combined.

Sift together the all-purpose flour and salt, then gradually add to the wet mixture, mixing until combined.

Use a cookie scoop or spoon to portion out the dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden.

Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
