Gently warm the milk in a small saucepan over medium heat. When small bubbles begin to form around the edges, whisk in the chocolate chips, cocoa powder and salt; whisk until smooth.
Scoop small scoops of ice cream into small tea cups or espresso cups. Ladle some of the hot chocolate over the ice cream and let the kids top with candy canes or gingersnaps if desired.
