Many of my keto recipes (including ones in The Easy Keto Carboholics’ Cookbook!) call for sugar-free sweetened condensed milk, and people often ask me where they can buy it. Unfortunately you can’t (that I know of), but the good news is it’s super easy to make your own low carb keto condensed milk recipe at home! You only need 3 simple ingredients and just 3 easy steps, but I do have some tips for you so it comes out just like the real thing.

The most important component of homemade low carb condensed milk is the sweetener. Besti Powdered Monk Fruit Allulose Blend is the best choice for this recipe, because unlike other keto sweeteners, it dissolves easily and completely, and won’t crystallize when it cools. It also tastes just like sugar, with no aftertaste, and has zero net carbs.

Ingredients You’ll Need

This section explains how to choose the best ingredients for homemade sugar-free sweetened condensed milk, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

  • Butter – Use unsalted.
  • Heavy Cream – This is sometimes called heavy whipping cream. Half and half or most other keto milk options won’t work, as the fat content is necessary for sugar-free keto condensed milk to thicken. Coconut cream or full-fat canned coconut milk should work as a dairy-free substitute, but the recipe still has butter and I haven’t tried replacing that. Please let me know (in the comments below) how it goes if you try a dairy-free version!
  • Besti Powdered Monk Fruit Allulose Blend – I wasn’t happy with the low carb sweetener options out there, so I made my own! This is my favorite and the only one I use now, because it tastes and acts just like sugar. As mentioned above, the most important characteristics it has for making sugar-free condensed milk are that it dissolves like sugar does and won’t crystallize, which is why it’s the only one I recommend for the silky smooth texture you want. However, plain powdered allulose will work equally well — you’ll just need 33% more of it. Almost all other brands of sweetener (including most brands of monk fruit and stevia) use erythritol as a bulking agent, which won’t dissolve well and crystallizes, so I don’t recommend them.
  • Vanilla Extract – This is not required, and not included in regular condensed milk, but feel free to stir it in at the end if you want that flavor.

How To Make Sugar-Free Sweetened Condensed Milk

This section shows how to make low carb sweetened condensed milk, with step-by-step photos and details about the technique. For full instructions, see the recipe card below.

  1. Melt butter. Place butter into a large skillet over medium heat and let it melt.
TIP: A large skillet is important.

TIP: A large skillet is important.

It may seem instinctive to use a saucepan, but it takes much longer (over an hour). Using a large pan with tall sides will help your keto friendly sweetened condensed milk cook in a reasonable amount of time, due to the larger surface area.

  1. Add cream and sweetener. Whisk in heavy cream and powdered Besti.
  2. Cook keto sweetened condensed milk. Bring the mixture to a boil, then reduce to simmer. Simmer until the consistency is thick and coats the back of a spoon and the volume is reduced by half.

Tips For The Best Keto Condensed Milk

Tips For The Best Keto Condensed Milk

  • Avoid a gritty texture. As explained above, I recommend using either Besti Powdered or powdered allulose, to ensure that the sweetener dissolves completely and won’t crystallize. If you use a different sugar substitute, both of these issues can result in a grainy texture.
  • Use a large pan. Remember to use a large skillet or saute pan, not a small saucepan, as smaller pans will take a very long time.
  • Cook for long enough. If your condensed milk is too thin, it needs to cook for longer. Just keep cooking it until it thickens. Also, this keto sweetened condensed milk recipe will thicken more as it cools from hot to warm.
  • But don’t cook for too long. If you cook your condensed milk for too long, it will brown and turn into sugar-free caramel sauce. Nothing wrong with that – just enjoy the caramel if this happens.
  • Don’t let heat get too high. Similar to cooking for too long, using too high heat will also turn your milk into caramel sauce.

Can You Make Unsweetened Condensed Milk?

I haven’t tried this, but in theory yes, you could make an unsweetened condensed milk recipe by omitting the sweetener. However, most uses for sugar-free condensed milk need it to be sweet.

How Many Carbs In Condensed Milk?

Regular sweetened condensed milk has over 20 grams of sugar (and carbs) per 2-tablespoon serving [*]. This keto condensed milk recipe is much better – it has just 1 net carb in that same amount.

Storage Instructions

  • Store: Low carb condensed milk stores very well, for a similar amount of time that opened heavy cream would. It’s good for at least a week, or until your cream’s expiration date.
  • What to do if it hardens: Low carb sweetened condensed milk won’t harden while cooking, but if it’s reduced a lot, it can harden when it cools to room temperature. It will definitely turn solid in the fridge, which is normal and actually beneficial for many recipes. See instructions below to reheat, which will make it runny again.
  • Reheat: Scoop the condensed milk (which may be solid) into a saucepan and reheat on the stove over low heat. Be careful not to overheat, and avoid using the microwave, both of which can cause it to separate.
  • Freeze: Yes, you can freeze this recipe! Store the keto condensed milk in an airtight container in the freezer for up to 3-4 months.
