I’m a big fan of cocktail, so when I started eating low carb I was super fearful that I’d have to give up my before dinner cocktail. But then I learned about sugar substitutes and tried a few out to see that they’re just as good in a cocktail as the real thing.

There are calories in a cocktail, of course, because alcohol has calories, but there are no carbs in clear spirits, like rum, vodka, mezcal and tequila. That means the only carbs you’ll add to a cocktail is from fruit and other additions. In a typical mojito, there’s a TON of sugar.

Keto Mojitos are made just like the original with rum, mint leaves, limes, sugar and soda water. The difference is that we substitute the regular sugar with a sugar substitute, like allulose or erythritol, that has no carbs or calories.

I use allulose as a sugar substitute. You can use Swerve, monkfruit, Erythritol or Xylitol. It’s really up to you. The reason I use allulose is because it’s a no calorie no carb sweetener like erythritol, but it doesn’t have the cooling effect. I get allulose directly through Wholesome Yum. I think you’ll really like it, especially if you also don’t like the cooling effect.

You can also use keto simple syrup for this recipe, which is a sugar substitute in liquid form. I like the one you can get from Wholesome Yum. It’s great to have on hand to sweeten your drinks!

Total Carbs in Keto Mojitos

There are 3 net carbs in a keto mojito. This is 5 total carbs minus 2 grams of fiber/sugar alcohol.

The carbs come from the limes. If you keep the glass small, you won’t need a full lime to make this drink and that will keep the carb count to 3 net carbs.

Ingredients in a Keto Mojito

As cocktails go this mojito doesn’t have too many ingredients. It’s handy to have a muddler to crush the lime and mint but if you don’t have one then you can use a spoon or fork. Here is the list of ingredients you will need.

  • Mint leaves – Don’t skip this ingredient. It adds so much flavor.
  • Lime
  • Sugar substitute – I use allulose as a sugar substitute. You can use Swerve, monkfruit, Erythritol or xylitol. It’s really up to you. You can also use keto simple syrup for this recipe, which is a sugar substitute in liquid form. I like the one you can get from Wholesome Yum. It’s great to have on hand to sweeten your drinks!
  • White rum – Look for white or silver rum at your local liquor store.
  • Ice
  • Soda water – Any soda water or tonic water, but make sure it’s a no sugar version.

How to Make a Keto Mojito

Here are the steps to make a keto mojito. What a fun name!

Step One: add about 8 mint leaves to the bottom of a glass. Pour in the sugar and 3 lime wedges. Muddle all of this together with a muddler (preferably) or the back of a spoon, until the lime juice is released and the mint is a bit crushed.

Step Two: Add ice to the glass. Right up to the top. Then add the rum.

Step Three: Fill the glass to the top with soda water. You can also use tonic water, but make sure it’s a no sugar version. Add a few fresh mint leaves and a slice of lime for garnish.

That’s it. One perfect mojito!

  • 8 mint leaves
  • 1/2 lime cut into 4 wedges
  • 2 tablespoon sugar substitute such as allulose or erythritol
  • 1.5 ounces white rum
  • Ice
  • Soda water


  • Place mint leaves, 3 lime wedges, and sugar into a short glass.
  • Use a muddler to crush the lime and muddle the juices. Fill the glass up with ice.
  • Pour the rum into the glass, then fill to the top with soda water. Stir. Garnish with the remaining lime wedge.


  • You can make a tall glass, if preferred, however half a lime is sometimes not enough to flavor that large of a glass, when filled up with soda water. Extra lime will add extra carbs.

    Oh that looks so good. After the stressful day I have had homeschooling, I could really do with one of these. Sharing!

      The short answer is yes, but you’d have to adjust the amount. The best thing about Xylitol is that it has a 1:1 sweetness with sugar and a similar graininess. Pure monk fruit sweetener is a lot sweeter than sugar and often comes in liquid form. It would really depend on what type of monkfruit sweetener you’re using. Mixed with erythritol would be the closest match.
