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)


  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.
  3. Remove from the heat and cool until tepid. Add the vodka and the vanilla. Homemade Low-Carb Kahlua
  4. Pour into bottles to store. It can be served straight away but tastes better after a few days/weeks. Homemade Low-Carb Kahlua
  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. Homemade Low-Carb Kahlua
  7. Serve over ice or use in cocktails such as White Russian (see intro for instructions on how to make it). Homemade Low-Carb Kahlua

What is the alcohol content of this preparation? 😊


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%


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.


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


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 😊😊


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


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


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


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?


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).
