Keto Condensed Milk

Keto sweetened Condensed Milk is a very easy recipe and such a versatile ingredient that can be used in so many low carb desserts.

If you were anything like me, there was a fair bit of condensed milk consumption as a kid.  Straight from the can, or making it into caramel and boiling for 3 hours.  Haha!

This low carb condensed milk without sugar is a perfect replacement. To be honest you won’t even know the difference if you use the ingredients listed.

Keto Condensed Milk is super easy to make at home. It is suitable for a low carb, keto friendly diet. It is both sugar-free and gluten free.

All you need is 3 ingredients

Cream – I use a thickened or heavy whipping cream rather than pure thin cream.

Sweetener – I use xylitol. Allulose will caramelise and turn it into caramel. Other low carb sweeteners will recrystallise e.g. erythritol, monk fruit sweetener.

Butter – I just use regular salted butter.

Frequently Asked Questions

Can I make dairy free keto condensed milk?

Yes, you can! You can make keto condensed milk with no butter or dairy. Swap thickened cream with coconut cream and leave out butter or add some coconut butter. I find it tastes sweeter than this version but perfect for a dairy free low carb option.

How long will it last in the fridge?

I have kept mine up to 1 month in the fridge. In saying that it does depend on the temperature in the fridge and how often your fridge door is open (hello kiddos).

Can I freeze condensed milk?

Some say yes, I say just keep it in the fridge. It can separate when taken back out of the freezer. It doesn’t freeze solid which makes it perfect for keto condensed milk ice cream and loads of frozen keto dessert recipes.

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.
