Preheat oven to 375°F. Line baking sheets with parchment paper. Set aside.
In a large mixing bowl, beat butter, brown sugar, and granulated sugar with electric mixer on medium until light and fluffy (about 3 minutes).
Beat in eggs one at a time, then add vanilla. Mix until smooth.
In a separate bowl, whisk flour, baking soda, and salt.
Add dry ingredients to butter mixture in two batches. Mix on low just until combined (don't overmix). Fold in chocolate chips with a spoon.
Scoop tablespoon-sized balls of dough onto prepared sheets, spacing 2 inches apart. Bake 9 minutes until edges are golden and centers look set. Cookies will firm up on cooling.
Let cookies cool on baking sheet for 5 minutes. Transfer to wire rack to cool completely.
