Cream Butters. Add sugars and beat in eggs and vanilla. Mix dry ingredients in a separate bowl, then add to egg and butter mixture and add chocolate chips. Bake at 375° for 10 minutes. Vania says it is better to bake one pan at a time, and to form the cookies into little towers, so they spread into perfect circles with a nice crackle pattern on top. And hers do look lovely. I shaped mine with a fork and they tasted just as good. Your choice. Enjoy!
