Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
In a medium bowl, whisk together the flour, baking soda, and salt until well combined and set aside.
In a large mixing bowl, use an electric mixer to cream the softened butter with both sugars on medium-high speed for 2-3 minutes, until the mixture is light and fluffy.
Beat in the eggs one at a time, followed by the vanilla extract, scraping down the sides of the bowl as needed to ensure everything is fully incorporated.
Gradually mix in the flour mixture on low speed until just combined, then stir in the oats and chocolate chips with a wooden spoon until evenly distributed throughout the dough.
Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
Bake for 10-12 minutes, or until the edges are golden brown but the centers still look slightly soft.
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely, which will allow them to set properly.
