Preheat the oven to 350°F (175°C).

In a mixing bowl, beat the softened butter and granulated sugar together until fluffy.

Mix in the egg and vanilla extract until fully combined.

In a separate bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry mixture to the wet ingredients, stirring until just combined.

Using a cookie scoop or tablespoon, drop rounded balls of dough onto a parchment-lined baking sheet.

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

Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack.
