No-carb root beer float

Low-carb root beer float

One of my favourite low carb drinks is a root beer float that uses sugar-free root beer and uses unsweetened whipped cream instead of ice cream. I use unsweetened whipped cream because the soda is usually sweet enough, but feel free to add a bit of sweetener to it if you like. If you are feeling really lazy, you don’t need to bother whipping the cream at all – just add a little bit of cream to a glass of sugar-free root beer, and you have yourself a lazy root beer float!

I’d love to use ice-cream in a root beer float, but I’ve never managed to find ice-cream that is completely carb-free. (If you know of a carb-free ice cream, please leave a comment and let us know where to find it! Also, keep checking back on this blog, because I’m working on a recipe for zero-carb ice cream that you can make in an ice-cream maker.

Try to find a brand of sugar-free root beer that doesn’t use aspartame. I’ve tried Zevia all-natural soda, which is sweetened with stevia.  I haven’t tried Hansen’s diet root beer personally, but it is sweetened with Splenda, so give it a try.

Update: I’ve recently acquired a Soda Stream machine, and their diet root beer flavour is fantastic! It’s sweetened with Splenda.  They’ve got a good line of sugar-free soda syrups without aspartame, so check them out.

Ingredients (4 servings)

  • 4 cans of sugar-free root beer 
  • ½ cup whipping cream (heavy cream)


  • Whip the cream.  See (how to whip cream in 30 seconds).
  • Put a few dollops of whipped cream in the bottom of a tall glass.
  • Pour root beer into the glass. The root beer will foam up as you pour it in, so do it slowly!
  • Stir and enjoy!
