Remove from heat, add the chocolate, and stir until blended. Add the cinnamon, clove, and nutmeg, and stir to blend. Divide hot chocolate between two mugs.
Optional Whipped Cream: Put cream (or coconut cream) and sugar in a chilled glass bowl, and use an electric hand mixer to whip into stiff peaks. Spoon onto hot chocolate.
