Step 1

Preheat the oven to 350 degrees F. Line two baking sheets with parchment paper, silicone liners or lightly grease with cooking spray.

Step 2

In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl with a handheld mixer, cream together the butter and sugars until light and fluffy, 1-2 minutes. Add eggs and vanilla and beat until creamy and well-combined, 1-2 minutes. Add baking soda, baking powder, salt and mix well. Add flour, oatmeal and chocolate chips. Mix until no dry streaks remain (don't go crazy; just mix until evenly combined).

Step 3

Scoop the cookies into balls (about 2 tablespoons each) and place a couple inches apart on the baking sheets.

Step 4

Bake at 350 degrees for 9-11 minutes.
