Stir the dry ingredients into the wet until just combined. I like to do this about ½ of the dry ingredients at a time. Fold in most of the chocolate chips. Reserve about ½ cup (85 g) for topping the cookie bars.
Bake for about 15 - 20 minutes or until the pan of cookies is a light golden brown and the edges are slightly pulled away from the sides of the jelly roll pan. Cool the bars in the pan to room temperature, slice and enjoy!
