Is ube the same as purple sweet potato?
No, ube is a yam from the Philippines. Genetically, ube is very different from sweet potatoes, even this purple one pictured here.
This recipe uses melted butter beaten into eggs and sugar rather than the creaming method used in many ube crinkle recipes. That gives these crinkles a chewy texture.

To get the classic crinkle look, scoops of cookie dough are coated in confectioners' sugar before baking.
