Unlike a lot of caramel sauces, this one stays soft and pourable in the fridge, it never hardens up the way you might expect. A few seconds in the microwave loosens it further if you want it warm for drizzling.

Chef Jenn’s Take on Caramel Sauce
This borrows a simplified version of the classic technique for caramelizing sugar, so it does not need to be complicated to get real depth of flavor. Melt the butter first, then add the brown sugar substitute and stir frequently for 3 to 4 minutes, until the foaming subsides. That foaming and settling is really the caramelizing moment happening in the pan.
Remove the pan from the heat completely before adding the cream, then add it all at once rather than gradually, stirring vigorously as you go. Adding the cream too slowly, or while the pan is still over heat, is what causes a sauce like this to separate or seize up instead of coming together smoothly.
What really sets this apart from a lot of other keto caramel sauces is that it stays soft and pourable in the fridge, it never hardens the way you might expect. A few seconds in the microwave loosens it further if you want it warm.
This is genuinely versatile too, drizzle it over keto ice cream, dip fresh berries in it, or use it in a layered dessert like Turtle Cheesecake Bites.
