This Coconut Chocolate Coffee Soda Recipe resembles an old-fashioned East Coast-style Egg Cream, except there's coconut milk and cold brew so it's decidedly different.
Make The Coffee Soda: Combine the chocolate syrup and coconut milk in the bottom of a tall glass and stir until evenly combined. Add ice to the top of the glass, top with the coffee, and stir. Garnish with a slice of orange and top with club soda or seltzer water to your liking (we liked 2 to 3 ounces).
