Preheat oven to 350 degrees F. Line a baking sheet with parchment paper. Set aside.
In a large mixing bowl or stand mixer cream together the butter and sugars. Add the eggs and vanilla and mix until smooth.
Add the oats to a blender and blend until powdered in texture. In a separate bowl, combine the flour, powdered oats, salt, baking powder, and baking soda.
Gently mix the dry ingredients into the wet ingredients. Stir in the chocolate chips.
Scoop cookies onto prepared baking sheet. Bake at 350 degrees for 9-11 minutes (a little longer for larger cookie scoops) or until the tops of the cookies are set (no longer doughy looking). Cookies will harden as they cool, so don't over-bake them. Allow them to cool on the baking sheet for a few minutes before transferring them to a cooling rack to cool completely.
