Butter Roll Cookie!

Butter Roll Cookie has egg-golden eyes with white borders and pupils, with the pupils able to take the shape of a four-pointed star whenever he's excited. He has voluminous hair with curls on the sides that spiral upwards and a tip that reaches down to his knees. The hair is colored light-yellow with an overall brown tone, granting it an appearance very similar to a large bread roll with small rolls on its sides. His dough is colored a medium-baked brown. Butter Roll Cookie wears a white chef's 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 wears a maroon-shaded pair goggles on his head, similar to a pair of laboratory goggles, and a large black silicone oven mitt on one hand. 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.

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.

Butter Roll Cookie spins his whisk, dealing damage and sucking in enemies at the center of the whisk vortex, reducing their ATK and ATK SPD, and increasing Butter Roll Cookie’s DMG Resist.
