Despite the name, this drink does not have any egg in it. A rich chocolate syrup is stirred into cream and your nut milk of choice and then topped with seltzer water for a lightly carbonated creamy chocolate soda.
Stir together the chocolate syrup, cream, and nut milk beverage. Divide between two glasses then slowly pour 3/4 cup seltzer water into each glass. There should be foam on top. Stir gently with a long spoon being careful not to disrupt the foam to mix the seltzer and chocolate milk.
