  • 450 g thickened or heavy cream
  • 140 g xylitol or allulose I use Xylitol, SEE NOTES
  • 70 g butter cubed



  • Add the ingredients to a small saucepan over medium/high heat.
  • Cook, stirring occasionally, for 40-50 minutes until mixture has begun to thicken. Cool and chill. The condensed milk will continue to thicken with chilling time.


  • Insert whisk attachment. Add ingredients to mixer; cook 60 min/100℃/speed 2/MC off/simmering basket in place on lid. Cool and chill. The condensed milk will continue to thicken with chilling time.


Xylitol is the only sweetener I recommend for this recipe. Why? Erythritol or monk fruit/erythritol blends will crystallise upon cooling. 
I like to use Xylitol Sweet for this recipe. It gives perfectly smooth, crystal-free condensed milk. 
Keto Eats Xylitol will thicken more but is still a good option.
PBco 100% xylitol seems to caramelise and crystallise. I am unsure why this is so, but on repeated tests it does not heat the same way other xylitol brands have shown.
A liquid allulose was also tested and made the condensed milk slightly caramel but soft and would still be perfect to use in any recipe that would lend itself to the caramel flavour.
Allulose will caramelise and turn the condensed milk into caramel.
The condensed milk will be still runny when it is cooked. Remove and chill. After chilling it will thicken slightly and be a perfect sugar-free condensed milk.
To make keto vegan condensed milk, paleo condensed milk, or unsweetened condensed milk (no sugar) and dairy free here are a couple of simple swaps. Swap the thick whipping cream with coconut cream and swap butter with coconut butter or leave out completely.
I have added more FAQs and tips in the post above should you need them. 
The recipe card highlights how easy it is to make sugar free keto condensed milk in the Thermomix. When the timer is up the mixture may still be runny but will thicken in the fridge or as it cools down.
Please note my recommendations of sweeteners.
