Preheat your oven to 350°F. Line two baking sheets with parchment paper.

In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

In a large bowl, using an electric mixer, beat the softened butter, brown sugar, and granulated sugar until creamy and smooth, about 2-3 minutes.

Add the vanilla extract and eggs, one at a time, mixing well after each addition.

Gradually add the flour mixture to the wet ingredients, mixing until just combined.

Fold in the butterscotch chips.

Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.

Sprinkle a small pinch of sea salt on top of each cookie.

Bake for 10-12 minutes, or until the edges are golden brown but the centers are still soft.

Remove from the oven and let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
