Preheat oven to 350 degrees. Line a cookie sheet with parchment paper. In a small bowl combine first 5 ingredients (dry ingredients). In a larger bowl beat sugars and butter until fluffy, and then add egg white and dry ingredients, beat well. Stir in chocolate chips. Shape into little balls and place on baking sheets. Press down with the palm of your hand (they won't spread, so press them as flat as you like your cookies). Bake for 15-20 minutes.
