Sugar-Free Condensed Milk

When the holidays roll around, you start seeing more recipes that use sweetened condensed milk, like pies and desserts, caramel sauce and dulce de leche. But on a low-carb diet, you can’t use it. That’s where this sugar-free version comes in handy.

I’ll tell you, the reason I love this recipe so much is that I can still make my favorite Vietnamese coffee, which is made with a thick layer of sweetened condensed milk and strongly brewed Vietnamese coffee poured over the top.

I fell in love with the drink a few years ago while touring Vietnam, and I really lamented it when I couldn’t make them any more once starting my keto lifestyle. Happily, I can now enjoy them again. Here’s a video of how to make Vietnamese coffee (watch it at 2x speed).

It’s also used in Thai Iced Tea, which I’m a huge fan of as well. Now it’s possible to make it without all the sugar.

I saw a sugar-free condensed milk in the market one time, but then I could never find it again, so I had to make my own.

It’s still just as sweet and can be used the same exact way you would use the sweetened version, it just uses a sugar substitute.

It’s made with heavy cream so it’s keto-friendly and tastes sweet and creamy.

Don’t confuse this with unsweetened condensed milk, which is something very different. This version is sweet, it’s just not sweetened with sugar.

How to Make Sugar-Free Condensed Milk

Here’s the best part. This recipe only has 3 ingredients! You’ll need heavy cream, a sugar substitute (allulose is best), and butter.

For the sugar substitute, you need to use a powdered version that dissolves well, like allulose. I’ve found that powdered erythritol doesn’t dissolve as well and makes the condensed milk a bit grainy or crystalized. To avoid this, use allulose.

A granulated version works in a pinch, but it won’t be as smooth and creamy – it’ll still have little flecks of granules that are undissolved.

  • Start by heating the butter in a saucepan over medium heat.
  • When melted, add the cream and sugar. Whisk it until it’s smooth.
  • Simmer the mixture over medium low heat for about 35 minutes, stirring occasionally. It will thicken as it simmers.
  • When it’s done, it can still be poured, but will stick to the spoon.

If after 35 minutes, the mixture is still too thin for your liking, continue to cook it until it has reduced enough.

I’ve found that when you cook it past about 45 minutes, it starts to caramelize or crystalize again. It’ll appear creamy, but when you store it, it’ll be too thick. So do keep any eye on it and don’t overcook.

Tips for Making Smooth and Creamy Sugar-Free Condensed Milk

The best tip I can give it to keep a close eye on the mixture as it reduces. It’s easy to overcook or scorch it if the heat is up too high.

You don’t want the mixture to boil, you just want it to simmer on a low heat. However, too low and it will take much longer than 35 minutes to cook it down. So you need to strike the right balance for your own stove. Then come back to it every few minutes to stir it and make sure the bottom isn’t browning.

What Sugar Substitute to Use

I use allulose as a sugar substitute. You can use Swerve, monkfruit, Erythritol or Xylitol. It’s really up to you. The reason I use allulose is because it’s a no calorie no carb sweetener like erythritol, but it doesn’t have the cooling effect. I get allulose directly through Wholesome Yum. I think you’ll really like it, especially if you also don’t like the cooling effect.

It’s important to note that allulose and Swerve are a 1:1 substitute for sugar. They have the same level of sweetness. However, erythritol is about 70% as sweet as sugar, so you will need to use 30% more erythritol for the same sweetness in this recipe.

Since all sugar substitutes can be a bit different in sweetness level, it’s always best to taste the mixture and increase the sweetness to your liking. You might think it’s sweet enough with just 1/2 cup of powdered sweetener. If not, just add more until you’re happy.

    I am so glad that I found this recipe. I love when I can use a little bit healthier ingredients when I bake.

    I have never tried making my own condensed milk before! I love that this is sugar free. 🙂

  3. Jessica Formicola says:

    This is such a helpful recipe! I don’t always have condensed milk on hand, so it’s great to now how to make my own!

  4. Rachna says:

    This is so very useful. I have never made my own condensed milk. Will definitely give this a shot.

  5. Kelli Mehl says:

    I don’t knownif it would work, but I saw on a regular sugar recipe for homemade condensed milk that adding a pinch of baking soda cuts the cooking time down to only needing 20 minutes……might be worth a try 🤷‍♀️

    • squid says:

      In this case, the pinch of baking soda would not be a good idea. It’s an alkaline agent and it raises the pH of the milk, which speeds up the the browning, which you specifically don’t want since allulose browns faster than sugar anyway.

  6. Christine says:

    You say erythritol is less sweet (it is) but in recipe it says if using erythritol cut down to 1/3 cup
    ( instead of 1/2 cup)
    So should alluose be 1/3 and erythritol 1/2 or should it read up it by 1/3 cup?

    • Laura says:

      Thank you for catching that mistake in the notes, Christine. It should say if using erythritol, increase the amount to 2/3 cup. It’s really a personal preference issue in the end, so it’s best to taste the mixture and adjust the sweetness to your own preference.

        I was looking for a recipe for condensed milk.
        I’m making homemade ice cream and it calls for condensed milk Will this work?

        • Laura says:

          Yes, absolutely. Just make sure to use powdered allulose so the condensed milk doesn’t crystallize.

  7. Lori says:

    Hello, I made this using confectioners erythritol but it crystallized when it cooled down. Can I recook the mixture by adding more heavy cream to it?

    • Laura says:

      I find that powdered allulose works best so it doesn’t crystalize. For some reason, erythritol has a tendency to do that. You can reheat and add additional heavy cream, but it will likely still crystalize.

  8. Marie Pecknold says:

    Can this be used in making a keto version of no-churn ice cream? I saw a recipe for no-churn ice cream, but it calls for sweetened condensed milk, which of course, I don’t want to use.

    • Laura says:

      Hi Marie. I’m not sure, to be honest. I’ve never tried it. This version is very similar to the regular SCM, but it can be more crystallized, which could mess up the texture of the ice cream. If you don’t mind a bad batch, you could give it a try to see. Report back if you do!

    • Laura says:

      Hi Sandra. I wouldn’t recommend using stevia in this recipe. The powdered version doesn’t dissolve very well and the liquid version doesn’t have enough substance to it to create the syrupy consistency of the condensed milk.

    • Laura says:

      Hi Robyn, you can use Splenda’s new allulose sweetener, but not regular sucrose-based Splenda. It’s far too sweet and would not produce the desired affect.

  9. Carol says:

    Hi 👋
    I’m looking for a version of condensed milk that is not so sweet. Can I make
    it without sugar? Maybe add some vanilla instead?

    • Laura says:

      Unfortunately the thickness is hard to achieve without the powdered sugar substitute. Using Erythritol or Allulose is the best way to get a less sweet version because it’s 70% less sweet than sugar. You could add 1/4 cup instead of 1/2 cup. Otherwise, you’d just have thickened cream.

  10. Ava says:

    I’m wondering if this could be made in a microwave? Every saucepan I use, (even for custard), gets brown on the bottom and sometimes even a burnt taste, even on a low temperature.

    • Laura says:

      I’m afraid I’ve never tried to make it in the microwave, so I don’t know, but it might be worth a try, if you don’t mind a possible failed attempt.

  11. Carin Rossouw says:

    Can sweetened condensed milk made with artificial sweetener be carinilized like ordinary bought sweetened condensed milk?

    • Laura says:

      It typically gets a bit grainy if you try to caramelize it, but I haven’t tried every type of sweetener. It’s possible there’s one that will work.
