2 Baking SheetYou can use one, but since you need to cook these in batches, using two speeds up the process significantly.

Ingredients
2Sticks Unsalted ButterSoftened - ½ Pound
1CupGranulated Sugar
½CupLight Brown Sugar Packed
½CupDark Brown Sugar Packed
2Large Eggs Beaten
2TeaspoonsVanilla Extract
2¾CupsAll-Purpose Flour(For a more accurate volume [cup] measurement, use a tablespoon to scoop the flour into the measuring cup and scrape the excess off the top.)
1TeaspoonBaking Soda
½TeaspoonsBaking Powder
1TeaspoonFine Sea Salt
2CupsSemi-Sweet Chocolate ChipsOne 12-ounce package - Reserve ¼ - ⅓ Cup to place some chips on top of the cookies just before baking.
In the bowl of a stand mixer, cream the butter and all three sugars on moderate speed for approximately 5 to 7-minutes until thoroughly combined and it turns a pale tan color.
Combine the beaten eggs and vanilla extract and add to butter and sugar mixture. Mix an additional 2-minutes until egg mixture is incorporated.
In a large bowl (while butter and sugar are being mixed), combine the flour, baking soda, baking powder, and fine sea salt and whisk to combine. While the mixer is off, add the flour mixture to the stand mixer. Combine on medium low speed until incorporated, approximately 1 to 2-minutes until a cohesive cookie dough forms.
Add in all but ¼ to ⅓ cup of the chocolate chips (reserving for later) and stir on low speed until just combined, 30 seconds to 1 minute.
Optionally, cover the dough and refrigerate for one hour, up to overnight.
When ready to bake, preheat oven to 375°F.
Remove the dough from the fridge and roll the cookies into balls that weigh 60 grams each (about two tablespoons). Place approximately 2 inches apart on a parchment paper-lined baking sheet.
Bake for 8 to 10 minutes, until the outside edges are set but the centers are soft.
Remove from oven and allow to cool for 2 to 3 minutes before moving to a wire rack to cool completely.
Repeat the shaping and baking process with the remaining dough. This will take several batches (usually three total) to bake all of the cookies.
Notes
The cooking time will depend on your individual oven. I start checking at 8 minutes, and usually will go no longer than 10 minutes.
