Espresso Cookie (Korean: 에스프레소맛 쿠키, esupureso-mat kuki) is an Epic Cookie available since launch. He is of the Magic type and his position is prioritized to the Middle.

Espresso Cookie is the esteemed pioneer and proponent of Coffee Magic, researching and experimenting through many sleepless nights to refine his craft. He resides wherever the best research opportunities lie, teaching at Parfaedia Institute before experimenting on Soul Jams at home in the Crème Republic and then moving to the Vanilla Kingdom to work alongside Strawberry Crepe Cookie.

Espresso Cookie exudes carefully-composed confidence while remaining understated. A no-nonsense intellectual, he loathes wasting time and harbors deep contempt for illogical ventures like White Magic and the Crème Republic's worship of the Divine.

Precise temperature, precise quantity of coffee beans, precise roasting time! Everything must be in a precise—impeccably precise—order for the plan to work. Always busy, always on the go—this is the lifestyle of Espresso Cookie. Despite being frequently mistaken for a black mage—yes, sometimes things burn, and smoke—Espresso Cookie can't afford to waste a second on meaningless explanations. Night after night, this pioneer of magic works on perfecting his grind and brew. "Isn't that too much coffee?" one might wonder. Well, at least there's always the delightful coffee fragrance in the air!
