Notes

SWEETENERS
Allulose is the only sweetener I recommend for this recipe. Why? Erythritol or monk fruit/erythritol blends will crystallise upon cooling. Xylitol makes a great condensed milk recipe but doesn't caramelize like allulose does.
A liquid allulose was also tested and made the sugar-free caramel slightly caramel but soft and would still be perfect to use in any recipe that would lend itself to the caramel flavour.
The syrup will still be a bit runny when it is cooked. Remove and chill.
SUBSTITUTIONS
To make keto vegan sugar free caramel syrup and dairy free swap whipping cream with coconut cream and swap butter with coconut butter or leave it 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 caramel syrup 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.
