Butter Roll Cookie wears a white chef-like uniform with yellow triangle-shaped buttons, thin black armbands, and maroon sleeves, as well as a maroon apron, a black buckled belt, and black pants and shoes. He is an unusually-positive and a happy cookie, despite the fact that his passion is in the preparation and handling of raw dough, something even the most villainous Cookies may find nauseating. Butter Roll Cookie is endlessly patient and encouraging to the researchers that work with him.
