Make sure the butter is soft (sitting on the counter works best for this but I zapped my for about 30 seconds on power 4 in the microwave). Beat the butter and peanut butter together until it is well combined.
Add the sugars and eggs and beat for about 2 minutes or until the mixture is frothy.
Combine the dry ingredients in a separate bowl.
Add the dry ingredients to the butters, sugars, and eggs mixture, mix for about 1 minute, making sure it is well combined.
Stir in the chips just until well combined.
Place dough in fridge for an hour or up to overnight. (optional)
Preheat oven. Place dough on a large cookie sheet 4 across and4 long, in balls that are about 1 1/2 inches.
Bake at 350 degrees for 8 minutes. Do not overbake, take them out of the oven just after they start to crack and let them finish cooking on the sheet as it cools down.
