Remove and discard cinnamon sticks, then fold in egg white mixture.
Sprinkle or grate Homemade Dairy Free Coconut Rum Eggnog with nutmeg to serve -- either in a large punch bowl or carafe.
Garnish each glass with dark chocolate shavings and a cinnamon stick if desired. Enjoy immediately!
Note: Homemade Dairy Free Coconut Rum Eggnog will keep for up to 2 weeks, refrigerated -- but I doubt it will last that long!
