Mix everything except chocolate chips in medium bowl until smooth. Stir in chocolate chips. Batter will be very sticky and wet. Line baking sheets with parchment paper. Scoop generous 1 tablespoon dough and place onto cookie sheet, space about 2 inches apart. Using moistened hands, shape dough on sheets to form balls.
Bake cookies until golden about 10-12 minutes. Cookies will still be very soft and not set. Leave cookies on sheet to cool and set.
