Sugar-Free Sweetened Condensed Milk is a versatile low carb ingredient for keto dessert recipes.

Many dessert recipes have been out of reach for people who don’t eat sugar but this keto friendly condensed milk now makes a lot of them possible.
We’ve based this recipe on heavy cream to ensure that the keto condensed milk is low carb while still providing a sweet and creamy taste.
We use this sugar-free condensed milk recipe as the base for our Low Carb Key Lime Pie and our Low Carb Jelly Slice recipes.

Is Condensed Milk Low-Carb?
No, normally condensed milk contains up to one cup of sugar per two cups of milk so it’s not low-carb or keto-friendly.
But as you can see with our keto condensed milk we don’t use whole milk but heavy cream instead and of course no sugar.
By using heavy cream we boost the fat content along with eliminating the high carb by using a natural sweetener in our case we use Swerve but you could use Natvia.

I made this recipe with Erythritol blend by simple truth and it didn’t work. Isn’t Erythritol blend what we needed? I’m Confused 🙁
Hi Ariana,
Can you describe how it didn’t work and I might be able to give you some tips. I personally haven’t used the Simple Truth brand so I’m not sure what could have gone wrong without further details.
How long does the prepared condensed milk mixture last in the refrigerator? I made a batch this past Christmas (December) and have some leftover (February).
Hi Cathy,
I don’t use mine past the expiry date of the cream, generally, it’s all used up within a week here. I would think that a month (maybe 2?) is a little bit too long to keep a fresh dairy product.
Please use your best judgment or as I always say “if in doubt, throw it out”
