Learn how to make a classic dirty soda at home with this quick and customizable base recipe. Made with soda, flavored syrup, and a splash of cream, this creamy specialty drink is perfect for parties, soda bars, or a fun family treat.

Ingredients

  • 1 cup ice
  • 12 oz soda of choice (Sprite, Coke, Dr Pepper, or root beer)
  • 1–2 oz flavored syrup (such as coconut, vanilla, raspberry, peach, or cherry)
  • 2-3 oz heavy cream

Optional Garnishes

  • Fresh lime wedge
  • Maraschino cherries
  • Whipped cream

Instructions

  1. Fill a tall glass with ice.
  2. Pour the flavored syrup over the ice.
  3. Slowly add the soda to preserve carbonation.
  4. Gently pour in the heavy cream and watch it cascade through the drink.
  5. Stir lightly if desired and serve immediately.

Notes

  • Start with 1 oz syrup, then adjust to taste depending on how sweet you prefer your drink.

  • Heavy cream creates the richest texture, but you can substitute half-and-half for a lighter option.

  • For a lower-sugar version, use diet soda and sugar-free syrup.

  • Always pour the soda slowly to prevent foaming.
