Preheat the oven to 350ºF. Line a baking sheet with parchment paper or a silpat.
In a medium bowl whisk together flour, baking soda, baking powder, and salt.
In the bowl of a stand mixer fitted with the paddle attachment, beat butter, granulated sugar, and brown sugar until creamy.
Add eggs and vanilla and mix until just blended.
Add in flour mixture and pulse until just incorporated.
Remove from the stand mixer and fold in the oatmeal and chocolate chips with a wooden spoon.
Shape the dough into 2 inch balls and place about 2 inches apart on the prepared baking sheet. Flatten the balls to ½ inch thick. Bake until lightly browned, 12 to 14 minutes.
Let cool slightly on the baking sheet before removing to a cooling rack to cool completely.
