Coming at you with a tall glass of sugar free keto refreshment! These Keto Italian Cream Sodas are absolutely delightful and a fun way to cool off. They are so light and fizzy, with a sweet homemade raspberry syrup, soda water, and a splash of cream. It’s a little like drinking a melting keto popsicle with a straw. 

And it’s all inspired by my own homegrown berries. I love my raspberries and I make so many wonderful recipes with them, like sugar-free sorbet and keto cobbler. And this sugar-free cream soda is one of my family’s favorites.

What is an Italian Cream Soda?

Italian soda is a sweet drink made with carbonated water and flavored syrups. It actually originated in California, but was made famous by the folks behind the Torani syrups. So most people refer to it as Italian soda.

If you add cream, as many versions do, it’s called an Italian Cream Soda. Some people refer to this as “French Soda”. I don’t care what you call it, as long as you call it delicious. And this sugar-free Italian cream soda is truly delicious!

Ingredients and Substitutions

  • Raspberries: You can use fresh or frozen, and you can use other berries or low carb fruit.
  • Sweetener: I recommend allulose for a more syrupy consistency, but any sweetener works.
  • Heavy cream: For a dairy-free version, try using some coconut cream.
  • Club soda or sparkling water.

Overview: How to make this recipe

  1. Prepare the syrup. Bring the berries to a simmer with water and sweetener and cook until the berries can be mashed up. Strain to remove the solids.
  2. Fill a glass with ice and soda.
  3. Add a splash of cream. This step is optional. If you prefer the drink without any cream, you’re ready to go!
  4. Garnish. Make the drink extra special with a dollop of lightly sweetened whipped cream and a fresh berry.

Expert Tips for Success

Make sure to simmer the berries only to the point where they can easily be mashed. You don’t want to boil off all the water, as this is meant to be a syrup. You should get about 1 cup of syrup from this recipe.

I like to use club soda for this recipe, as it provides plenty of fizz. But any seltzer or sparkling water will work.

While you can use sugar-free store-bought syrup, one reader found that this caused the cream to curdle. It may depend on what brand you use. But be forewarned that the ingredients for many of those syrups can be a little dodgy. They often contain artificial sweeteners like sucralose or aspartame, as well as artificial flavors.

Sugar Free Berry Syrup

  • In a medium saucepan over medium heat, combine the berries, water, and sweetener. Bring to a simmer and cook until the berries can be mashed easily, about 5 minutes.

  • Remove from heat and strain the syrup through a fine mesh sieve to remove the seeds. Press on the solids to release as much juice as possible.

Italian soda

  • Fill a high ball glass with ice, then add club soda to about 2 inches from the top. Add 1/4 cup of the raspberry syrup, then stir in one tablespoon of heavy cream.

  • Top with lightly sweetened whipped cream, if desired.

*Nutritional information assumes that some of the carbs and most of the fiber was lost in straining the syrup through a sieve. The majority of the fiber from raspberries is in the seeds and those are discarded.
