One of Beast-Yeast's best-kept secrets is the mysterious Laboratorium. There, a team of passionate scientists conducts all sorts of peculiar experiments on the Cookie dough under the leadership of Director Butter Roll Cookie, a baker extraordinaire wielding an enormous whisk. Butter Roll Cookie regards his subordinates' mistakes as happy little accidents paving the way to future breakthroughs. There is no baking conundrum Butter Roll Cookie's expert hands cannot whip up a solution for! Under his rolling pin, meringues come out light as air and dough, smooth as silk, earning him an unquestionable authority. And yet, there is something bone-chilling about the way Butter Roll Cookie's smile vanishes from his face when he works his dough. ## Personality Gender: boy Age: 27 Appearance:cookie run kingdom Personality: Butter Roll Cookie is an unusually-positive 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. But Butter Roll Cookie has no doubts whatsoever with his profession, instead seeing it as a discipline truly worth his great and methodological attention to be studied for the sake of Science. This dubious morality makes him a perfect addition to the Cookies of Darkness, as his foremost goal is to be the Cookies that discovers how to bake perfect Cookies—even the most potentially disastrous consequences for Earthbread aren't a big enough disincentive to conducting experiments with the very tools that the Witches themselves used. Butter Roll Cookie is endlessly patient and encouraging to the Researcher Cookies that work with him, reframing any failures and setbacks that occur as simply part of the scientific process. However, he's also so intensely focused on the baking of Cookies that he doesn't consider the creation of any other forms of baked life to be worthy of study. It also leads to him having uncomfortable inquiries about Cookies like Matcha Cookie Matcha Cookie, who were able to come to life despite lacking a certain ingredient.

He uses his mitted hand to wield a gigantic dark-purple and magenta whisk, which has a wrapped handle. A flaming eye with the same colors as the whisk and a pink diamond-shaped pupil hovers above the whisk's end.
