Sugar Free Rhubarb Mojito

The perfect refreshing sugar free and low carb mojito, made with a keto sugar free rhubarb simple syrup! Have your cocktail and forget the carbs!

This week’s Bon Appeteach “Book Club” cocktail was inspired by the classic Nicholas Sparks novel, A Walk to Rum-Member…. yup, rum-member that one from 1999?

I do. #causeimoldnow

This week’s rum inspired cocktail, is a riff on a classic mojito. Summer months always remind me of rhubarb season, and it’s fairly low in carbs and brings a unique flavor profile to a classic cocktail.

I created a keto, sugar-free, rhubarb simple syrup using my keto simple syrup recipe. You can easily use regular sugar too if that’s your jam.

Find the full recipe below for this delicious rhubarb-infused sugar-free Mojito, and read on for a few tips and tricks to making the perfect crowd pleasing, low-carb rum cocktail!

“School” Supplies:

  • 3 oz Rhubarb Simple Syrup (see ingredients below)
  • 2 oz White Rum
  • 4-5 Mint Leaves
  • 1/2 Lime, juiced
  • Ice
  • Extra Mint & Rhubarb stalks for garnish

“Class” Notes:

I love when you can build a cocktail right in the glass! It makes it that much easier and also I love it when there are fewer dishes. I did make the rhubarb keto simple syrup ahead of time for ease, but it can still be made the day of and used, just plan ahead a little so it has time to cool!

In a Collins glass, I start by muddling a few mint leaves. This should be a gentle motion that releases the natural aromatics and oils in the mint leaf.

 Squeeze in the juice of half a lime, add the rhubarb syrup, and then the rum!

Next, pour in crushed ice and top with club soda. Add a few more mint springs for garnish and I made a fun rhubarb ribbon with my peeler to make a pretty garnish. But also, feel free to just stir it a bit with a straw and drink it down. Because it’s delicious.
