Low Carb, Sugar Free Tropical Mule recipe backstory
I don’t know about y’all but I’m so happy when the weather warms up. I’m tired of looking out the window at bright, sunny days that promise blessed warmth and slap me in the face with cold winds when I open the kitchen door to let the doggies out.
This year my Christmas gift to the family was a week long cruise in the Caribbean. We left January 7 and experienced really beautiful weather for the most part, although a few of our sea days were choppy and chilly. I could tell who the northerners were, they were the ones in the pool when I was on my balcony in a coat.
I did spend a glorious day on the beach where I managed to hold this styrofoam cup filled with a tropical cocktail long enough to snap this picture. Yes, I did the one thing that everyone does but I never had, I sipped a frozen pina colada on a tropical beach. Actually I sipped several of them. The only thing that could have made them perfect was if they were served in coconuts.

What is a Moscow Mule?
All vacations come to an end however, and I’m back on my low carb lifestyle. I managed to spend a week on a cruise ship and not gain weight so that made me happy. I did miss those yummy cruise ship cocktail concoctions.
Moscow mules are made with vodka, ginger beer, ice, fresh lime juice, and lime wedges. They are usually served in copper mugs. Unfortunately the regular ginger beer used to make a Moscow Mule is carb heavy. That means one regular Moscow Mule has 15 carbs. That’s too much for me.

How to make a low carb, sugar free Tropical Mule
I wanted to make a Moscow Mule that reminded me of those tropical cocktails I had while on that cruise. To make a low calorie, low carb version, I added sugar free tropical flavors of pineapple, coconut, and ginger flavors along with a few frozen cranberries for color and to keep the drink chilled without watering it down. Using sugar free ginger beer reduces the sugar and carbs. My go to low carb cocktail ingredient is sugar free flavored water enhancers. They add all the flavor of the usual high carb ingredients like pineapple juice, orange juice, and simple syrup but without all that sugar. Oh, about those frozen cranberries, (1) you don’t have to add them, and (2) they don’t add calories OR carbs because you don’t eat them. They don’t taste great anyway, trust me on this one. If you don’t have them, a lime slice, mint leaves, or mint sprig works great too.
This tropical version of the Moscow Mule is sparkly from the sugar free ginger beer and club soda. If you like your low carb cocktails a little heavier, add a little sugar free sweeter, then use more ginger beer and add the club soda to lighten it up.
This Moscow Mule done tropical style is one of my favorite cocktail recipes for chilly weekend afternoons curled up on the couch with Netflix and a 1960s bikini movie. It’s also great for entertaining from early Spring to late fall. Or as I jokingly say, only on days that end with the letter “y”. I swear one of these days I am going to do a 1960s style Hawaiian luau party with these tropical Moscow Mules.

Mule Recipe FAQs
Here are some facts and trivia about the mule cocktail.
- How do you make the best Moscow Mule? Be sure to use a good vodka. There aren’t a lot of ingredients in this low carb cocktail so the ones you use must be high quality. Top shelf brands cost more, but sure taste so much better and make an awesome cocktail. Use a sugar free, spicy ginger beer, not store brand ginger ale.
- Why does a Moscow Mule have to be in a copper cup? Besides tradition, the benefit of serving a Moscow Mule in a copper cup is that the copper keeps the cocktail cold. Personally I don’t like the feel of copper on my lips so I always ask for mine in glass.
- Are ginger beer and ginger ale the same? Not at all. Ginger beer is brewed and fermented, although it remains non-alcoholic. Which is why Harry, Hermine, and Ron had them in the Harry Potter movies. Ginger ale is just ginger flavoring added to carbonated water.
- Can ginger ale be used as a substitute for ginger beer? Yep, it can but doesn’t taste nearly as good. See above.
- Do flavored vodkas have more carbs than plain vodka? Some of the cheaper ones do. The bigger, higher end companies make theirs in such a way that the flavors don’t give the vodka carbs or extra calories.
- How do you make a Kentucky mule? A Kentucky mule uses bourbon instead of vodka. Bourbon is too heavy in my low carb Moscow Mule recipe. I suggest sticking with vodka. On a warm day, keeping your vodka in the freezer adds a refreshing, crispness to the drink.
