These chocolate crinkle cookies are coated in confectioners' sugar for a decadent chocolate treat. They look beautiful on Christmas cookie trays and taste so good!
For optimal flavor and texture, ensure the dough chills for the full 4 hours, or even overnight; this also makes it easier to handle. Use a high-quality unsweetened cocoa powder for a richer, deeper chocolate taste. When coating, roll the dough balls generously in confectioners' sugar right before baking to achieve the most pronounced crinkle effect. Do not overbake; the cookies should still be slightly soft in the center when removed from the oven, as they will continue to set as they cool.
