Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. In a medium bowl, whisk together the flour, baking soda, and salt, then set aside.
In a large bowl, beat the softened butter, brown sugar, and granulated sugar together until creamy and smooth. Add in the vanilla and eggs, mixing until everything is well combined.
Gradually stir in the dry ingredients until just combined, then fold in the oats and chocolate chips.
Drop spoonfuls of the cookie dough onto the prepared baking sheet, leaving some space between each cookie.
Bake for about 10-12 minutes until the edges are lightly golden, removing them from the oven and letting them cool on the baking sheet for a few minutes before transferring to wire racks.
Notes
These cookies can be stored in an airtight container for up to a week—if they last that long!
