Homemade Low-Carb Kahlua (keto, sugar-free, grain-free)

Well helloooooo to my new favourite thing!

Keto Kahlua is so easy and so, SO tasty that you are going to wonder why on earth you didn’t think of it sooner.

The hardest part of this recipe is how incredible your house will smell when you make it, while known that you need to let it develop fully in the bottles for 2-4 weeks. If you plan to keep your low-carb kahlua refrigerated, use allulose as it won't crystallise.

Between you and I? It still tastes awesome on day one, it just tastes even better after a few weeks to fully develop the flavours, so I won’t tell anyone if you have a sneaky White Russian after making it.

Even if this Mexican coffee liqueur is not your thing, check out our Low-Carb Amaretto, Low-Carb Baileys. Enjoy!

How To Make Low-Carb White Russian

This low-carb Kahlua is the perfect base for tasty cocktails such as White Russian. You'll need:

  • 2 shots (60 ml/ 2 fl oz) of vodka
  • 1 shot your homemade Low-Carb Kahlua (30 ml/ 1 fl oz)
  • ice to taste
  • 2 tbsp heavy whipping cream (30 ml)

To make low-carb White Russian cocktail at home, simply fill your glass with ice. Add the vodka, homemade Low-Carb Kahlua and mix. Pour a splash of cream over the top and swirl to combine.

Step-by-step

  1. Prepare all the ingredients for the low-carb kahlua. Start with the coffee. The better the coffee, the better the end result. I used fresh brewed espresso.

  2. Combine coffee, erythritol and water in a pan over medium heat and stir until the sweetener is completely dissolved. This is important, otherwise you can get a film on the top of your bottle. It won’t hurt, it just doesn’t look as nice if you are planning to gift the bottles.

  3. Remove from the heat and cool until tepid. Add the vodka (or you can use dark or light rum) and the vanilla.

  4. Pour into bottles to store. It can be served straight away but tastes better after a few days/weeks.

  5. Allow to fully cool before capping.

  6. Store in a cool, dark spot for 2-4 weeks before opening. If you do get a film on top, just give it a shake before opening.

  7. Serve over ice or use in cocktails such as White Russian (see intro for instructions on how to make it).

    kaluah is actually made with rum? so why yhe use of vodka?

    1. Martina @ KetoDietAuthor

      Rum is an option too! There are actually a few variations so this is a variation with vodka.

  2. Louise

    This is what I have been looking tor. Thank you. Mmmm Keto Black Russian. How long does it keep for?

    1. Martina @ KetoDietAuthor

      It should keep for several months, 6 months for sure 😊

  3. Karen Smith McDonald

    You must try this Keto Kahlua over Keto icecream and shave some SF chocolate on top for a wonderful dessert

    1. Martina @ KetoDietAuthor

      That sounds wonderful, thanks for the tip!

  4. Annette Symonds

    Just finished making this recipe. Can't wait until happy hour!
    One concern...I just started the keto diet and on the erythritol package it says it's 4gm of carbs per teaspoon so that's a lot of carbs in 2 cups of this sweetener. Can I use Stevia as that is 0 carbs?
    Why on the nutritional breakdown that per ounce it is .05 carbs. How can that be?

    1. Martina @ KetoDietAuthor

      I am so sorry Annette, I'm not usually this late to reply to a comment but these last two months have been too busy. Please see my comment below - it's absolutely fine as all those carbs are from sugar alcohols and Erythritol doesn't affect blood sugar.

  5. Dennis Munro

    How can the carbs be so low when erythritol saya 4 carbs per teaspoon?

    1. Martina @ KetoDietAuthor

      Here's why: Top 6 Keto Sweeteners and Low-Carb Sweetener Conversion Chart (Erythritol has almost no calories and no effect on blood sugar. All those carbs are sugar alcohols.)

    Hi, I just ran across your recipe and I have a question. Like someone else mentioned below, I am not a fan of sweeteners, so I plan on going 100% sweetener free. My question is how long is the shelf life for this recipe in the
    a) refrigerator and
    b) room temperature in my liquor cabinet?
    Thanks, so excited to make a white russian with my homemade coconut-cashew milk!! =)

    1. Martina @ KetoDietAuthor

      That sounds great, I'll need to try making that milk myself!😊
      I'd only be guessing based on general recommendations but I'd say it should be definitely fine for a year, some sources suggest up to 4 years if stored properly. I would not store it in the fridge if you use Erythritol because it will crystallize. If you use Allulose then you can keep it refrigerated. I hope this helps!

  7. Allison

    I’m going to make this tomorrow and very excited about it. Have you tried the recipe with liquid Allulose? How much should I use? Thank you!

    1. Martina @ KetoDietAuthor

      I have not tried that but I bet it's even better! Both liquid and granulated allulose would be good options here. Let me know how it went!

  8. Scott Miller

    Okay, help me out here. The instructions call for strong coffee, but then you dilute it with one cup of water. Why wouldn't you just make regular coffee?

    1. Martina @ KetoDietAuthor

      Good point, you can do that too, as long as you use the same amount of water.

  9. Richard Ayres

    Just made this and of course had to immediately try it. Found it really good! Looking forward to trying it after it has aged.
    I pulled nine 2.75 ounce shots of espresso including the crema to get 16 ounce of espresso from Malabar Gold beans. I used hot water from the brewer (205 degrees), it instantly dissolved the Swerve making this a supper easy process. The granular Swerve came in a 12 oz (340g) container, a little less than the recipe calls for, but I don’t think it mattered. Next time I'll cut the ingredients in half thinking that should just about fill an empty Kahlua bottle (740 ml).
    For the cocktail I fill a glass full of ice, pour Keto Kahlua over the ice till about half full and the remainder with half and half. Delicious!
    I'm wearing a continuous blood glucose monitor and after three drinks (had to give it a good test) and three hours, glucose level stayed flat, no spike, virtually no movement at all, Woohoo!
    Thanks so much for posting this recipe!!!

    1. Martina @ KetoDietAuthor

      Thank you for sharing this Richard! Less sweetener is definitely not an issue. I love making White Russian with this liqueur, it's so good!

  10. Jean

    I just made this recipe, kept it in the fridge and every few days it had a thick sludge on the bottom, but I gave it a shake and it blended. I forgot to check it for about a week and when I did there was a hard crystallized substance on the bottom which I could not shake up. I reheated the kahlua, poured small amounts back in the bottle until crystalized substance eventually dissolved. I thought I boiled it long enough initially to dissolve the sweetener. Do you have any idea what I might have done wrong? It tastes great, though!

    1. Martina @ KetoDietAuthor

      Hi Jean, this what happens with most the low-carb sweeteners. You could use Allulose instead which should prevent any crystals from forming. It's a bit more expensive and not always available but I think it's worth it. Another option would be to use Allulose syrup.

  11. Simone Meurant

    Brilliant! Just found your page by accident - looking for a low carb Kahlua recipe. Just made one batch, substituting about half a cup of granulated sweetener with 1/4 teaspoon - maybe even less, of pure Monkfruit (only because I ran out...).
    I used Xylitol - which in Australia is easily available - erythritol is way harder to find. Tastes fabulous now!
    Thank you - you have a new follower and will check out your FB and app.

    1. Martina @ KetoDietAuthor

      I'm glad you enjoyed Simone! ❤️

  12. Steven

    Hello my wife and I attempted to make this recipe and it didn't turn out very well. We thought the sugar was dissolved but each bottle has a thick layer of sugar sitting in the bottom and it tastes nothing like Kahlua, the vodkas presence is very apparent. The coloration is off as well, its more of a brown like broth. How long is it supposed to take to dissolve the sugar when you first mix? We're just not sure what went wrong.

    1. Martina @ KetoDietAuthor

      Hello Steven, that sounds strange, I made a similar liqueur (I also added some cream) and it worked well. One thing... Did you by any chance use xylitol or other low-carb sweetener? This happened to me once and the sweetener got stuck to the bottom of the pan. If you use any erythritol based sweetener or allulose, the sweetener should dissolve in hot coffee, you just need to stir and cook on medium-low until dissolved. Allulose is a new sweetener that is probably the best option for this.
      As for the colour, this is only affected by the type of coffee - maybe it wasn't a strong brew and looked more brown/weak?
      I'm sorry to hear this was disappointing, I hope these tips help!

  13. Kelly

    What is the alcohol content of this preparation? 😊

    1. Martina @ KetoDietAuthor

      That would be about 15%. The way to calculate alcohol content in this is:
      (Volume of vodka x ABV% / Sum of Ingredients) x 100
      (480 ml x 40 / 1,300 ml) x 100 = 15%

  14. Diane

    This my third time for making this recipe. It is wonderful and so delicious in my coffee when taking a mid morning break. Love how easy it is and the taste is so good. I have bottled and labeled my Kahlua and given it away during the holidays. Thanks again for sharing!!! xoxoxoxoxoxoxoxo.

    1. Martina @ KetoDietAuthor

      Thank you so much Diane! I love this with a dash of heavy cream 😊

  15. Jennifer

    What size of bottle will I need or how many? Wanting to make this today and want to be prepared. Thanks so much for posting this I love Kahlúa and was really sad without it 😊😊

    1. Martina @ KetoDietAuthor

      Hi Jennifer, this will make about 1.3 L so it depends on the size of the bottle - 2 to 3? 😊

  16. Tamara Middleton

    I'm not a fan of sweeteners ..... Can i forego the erythritol?

    1. Martina @ KetoDietAuthor

      The sweetener is only used for for taste so if you don't mind sweetener-free you can do that 😊

  17. Becky

    Making the Kailua now. I didn’t read all instructions. I added the erythritol after Everything else. Can I heat with the vodka in it?

    1. Martina @ KetoDietAuthor

      Have you tried dissolving it just by stirring? It may take time but it's better not to het it up as you'd lose some of the alcohol (unless you don't mind).
