An electric drinking cup for use while driving a vehicle comprised of a plastic inner liner, a metal outer shell, and an insulation-filled space therebetween. A heating element is associated with the bottom portion of the inner liner, and is electrically connected to a vehicle's electrical system. The plastic inner liner curves around the upper edge of the outer metal shell providing a cup lip, which does not get hot when containing a hot liquid. The plastic inner liner and heating element further provide a diffuse heat that heats liquid, such as coffee or hot chocolate, slowly to the desired temperature such that, when heated, the liquid does not become burned and distasteful. The outer metal shell provides durability.
