Gradually add the flour mixture on low speed until combined, about 1 minute. Stir in chocolate chips by hand.
Drop tablespoons of dough onto ungreased baking sheet 2 to 3 inches apart. Bake for 12 to 14 minutes until cookies are golden brown around the edges. Let cookies cool slightly on pan then transfer to wire rack to cool completely.
