Cold Chocolate Soda – when Fizz Meets Fantasy

Today’s the day, November 19, when we raise a fizzy toast to Carbonated Beverage with Caffeine Day. But, hold the standard soft drinks—I’m opting for a quirky twist. Instead of reaching for the usual soda can, I’m diving into the realm of Chocolate Soda. Yep, you heard it right—chocolate and bubbles colliding in a sweet symphony. Who needs a regular cola when you can sip on a concoction that combines the best of both worlds?

At first, the idea of Chocolate Soda seemed downright bizarre to me. I mean, chocolate is my absolute favorite—no arguments there. I can mix it with other ingredients to make different drinks, from chocolate cocktails and mocktails to smoothies and milkshakes. But with carbonated water? That’s a whole different thing. I couldn’t wrap my head around how these two could coexist in a single beverage.

I hesitated, I doubted, I even doubled about it. How could the rich, indulgent flavor of chocolate possibly mesh with the effervescence of carbonation? It sounded like a recipe for taste bud chaos.

However, curiosity got the better of me, and I decided to make this Chocolate Soda recipe and it was unexpectedly good. The chocolate was velvety and familiar, but the carbonation added this unexpected zing. The contrast somehow worked wonders, creating a unique and surprisingly refreshing experience.

This is how I made Chocolate Soda: mixing chocolate syrup or cocoa powder with carbonated water.

  • Maraschino cherry optional


  • In a tall glass, add 2 tablespoons of chocolate syrup.
  • Pour in 1 cup of cold milk and stir well to combine with the chocolate syrup.
  • Add 1 or 2 scoops of vanilla ice cream to the glass.
  • Slowly pour club soda into the glass, allowing it to mix with the chocolate milk and create a foamy top.

If you don’t have chocolate syrup, you can make it by combining 2 tbsp cocoa powder, 2 tbsp sugar, and 2 tbsp hot water together. Stir until the sugar is dissolved.
