An insulating lid includes a cover having an outer edge and a base. The base includes an upper surface, a lip projecting upwardly from the upper surface about an outer perimeter of the base to define an inner area, and a plurality of spacer members extending upwardly from the upper surface positioned within the inner area. The plurality of spacer members are configured to space the cover a distance from the upper surface of the base to define an insulating space between the cover and the upper surface of the base.
