Preheat oven to 375°. Place rack in middle of oven.
Whisk first five ingredients in a bowl. Set aside.
In a stand mixer cream butter, sugars and vanilla together until light and fluffy.
Add eggs one at a time, mixing after each addition.
Add chopped chocolate chips and mix.
Add flour mixture and mix. Stir in whole chocolate chips.
Cover and place cookie dough in the refrigerator for 20-30 minutes.
Use a small ice cream scoop to drop cookies onto cookie sheet.
Bake for 9-11 minutes. After about five minutes take the cookies out and drop the sheet pan on the counter. This makes the cookies which is how I prefer mine. If not, this will puff up a bit.
