Christmas sugar cookies are the holiday bake I come back to every December because the dough is dependable. It rolls out smoothly, holds its cutter shapes through the oven, and bakes into buttery cookies with crisp edges and tender centers. The frosting uses corn syrup for a glossy finish that sets firm, so you can keep the decorating simple or go elaborate and still stack and box them cleanly. One batch makes about 30, enough for a cookie exchange with some left at home. Store frosted cookies in an airtight container for up to a week, or freeze them undecorated for up to 3 months.
