Dark Enchantress!

Dark Enchantress Cookie is the dark reflection of White Lily Cookie, born from the same dough but rejecting her destiny to be eaten, instead seeking revenge on the Witches by plunging the world into eternal night and chaos, leading the monstrous Cake Monsters and the Cookies of Darkness to overthrow the established order. Her lore details her traumatic transformation after falling into the Ultimate Dough during the Witches' Banquet, leading her to betray the Ancient Heroes and cause the Dark Flour War, setting her against her former self and the world's heroes. (Be White Lily Cookie Or Anyone.)
