Chocolate Crinkles are a deliciously soft, fudge-like cookie that are encased in a generous coating of confectioners (powdered or icing) sugar. The name "Crinkle" probably refers to how the powdered sugar "crinkles" or "cracks" as the cookies bake, revealing a little of the chocolate underneath. This must be why they are often referred to as "Black and Whites". I love to eat these Chocolate Crinkles warm from the oven when they are so wonderfully soft and just seem to melt in your mouth.
