Homemade Low-Carb KahluaPin itFollow us 148.4k

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.

Ingredients (makes about 1.3 L)

  • 2 cups strong brewed coffee, ideally espresso or Swiss water process decaf coffee (480 ml/ 16 fl oz)
  • 1 cup filtered water (240 ml/ 8 fl oz)
  • 2 cups vodka or dark or light rum (480 ml/ 16 fl oz)
  • 2 cups granulated low-carb sweetener such as Erythritol, Swerve or Allulose (400 g/ 14.1 oz)
  • 2 tbsp sugar-free vanilla extract (30 ml)

Instructions

  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. Homemade Low-Carb Kahlua
  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.

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

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?

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.

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!!  =)

Martina @ KetoDiet 4 years ago # Reply
4/3/2021 12:31:24 PM

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!

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!

Martina @ KetoDiet 4 years ago # Reply
3/4/2021 2:42:34 PM

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!

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?

Martina @ KetoDiet 4 years ago # Reply
2/8/2021 5:21:57 PM

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

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!!!

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!

Martina @ KetoDiet 4 years ago # Reply
12/20/2020 1:19:34 AM

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.

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.

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.

Martina @ KetoDiet 4 years ago # Reply
10/7/2020 10:13:25 AM

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!

What is the alcohol content of this preparation? 😊

Martina @ KetoDiet 4 years ago # Reply
8/19/2020 7:43:41 PM

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%

Martina @ KetoDiet 5 years ago # Reply
3/19/2020 9:14:26 PM

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).
