This simple sugar free condensed milk recipe will take your keto baking to new heights! It takes only 5 ingredients and 30 minutes of your time. Use it in a wide array of other keto dessert recipes.
Being passionate about baking, I am never without a jar of this sugar free condensed milk in my fridge. Because I never know when the urge to bake will strike and I must be prepared. It’s vital to my sanity.
I’ve always had a kitchen cupboard dedicated entirely to baking supplies. And I don’t mean a weeny little half-section either, but a full cabinet bursting at the seams with all of the staples I might need at any given moment
Going keto hasn’t changed that. If anything, I find it even more important to have my supplies close at hand, so I can satisfy my sweet tooth with healthier treats.
And this sugar-free sweetened condensed milk allows me to make easy keto desserts at a moment’s notice!
Why you need this recipe
Many of the recipes we all grew up making call for sweetened condensed milk. Just consider it: magic cookie bars, fudge, ice cream, frosting. It’s a staple in American (and Canadian!) baking.
But it’s not like you can go out and purchase a can of keto condensed milk at the grocery store. So the only choice you have is to make your own.
Thank goodness it’s so easy to make! It takes 5 basic ingredients and only 30 minutes of your time. And it lasts in the fridge for up to two weeks, so there is no reason to go without.
I was one of the first to ever create sugar free condensed milk. But I am always striving for better results in my recipes. And with the introduction of many wonderful new products, especially sweeteners, I have made this recipe ever better.
It now stays soft and gooey, without any recrystallization. Even after days in the fridge! And it has only has 1.25g of carbs per serving. This is keto baking magic, my friends.

- Heavy whipping cream: As the name suggests, conventional condensed milk is made with milk, rather than cream. But heavy cream has far fewer carbs and thickens up faster, so it’s perfect for keto condensed milk. You can also use full fat coconut milk but you may need to add a bit more thickener at the end.
- Sweeteners: You really do need a combination of two sweeteners for this recipe. Using allulose or Bocha Sweet helps keep it soft so it won’t recrystallize as it cools. But the addition of some Swerve Confectioners helps it thicken properly and not be overly goopy. It also keeps the cost down and the end result is perfection!
- Butter: The butter makes the condensed milk a bit thicker and richer. Use unsalted butter for this recipe.
- Xanthan gum: Using a bit of xanthan gum helps give the sugar free condensed milk a thicker, more syrupy consistency. You could also try gluccomannan.
Step-by-step directions
1. In a large heavy saucepan, whisk together the whipping cream and sweeteners. Bring to a boil.
2. Reduce the heat and simmer gently for 30 minutes. Watch carefully as you want it to simmer but not continue to boil. There should be little bubbles along the edges the whole time.
3. Remove from heat and add the butter. Whisk until melted.
4. Sprinkle the surface with xanthan gum and whisk vigorously to combine. Let cool completely.
Expert tips
Two Sweeteners is the key: The combination of sweeteners is vital to the success of this keto condensed milk. Using just one or the other simply doesn’t produce the right consistency. Erythritol-based sweeteners, such as Swerve, recrystallize too much as they cool. But using only allulose or BochaSweet could make it too goopy, so that your desserts never firm up properly.
Allulose also tends to caramelize very easily. So if you cook it too long or at too high a heat, the mixture darkens in color. In fact, it was this very discovery that lead me to create my Keto Dulce de Leche!
Let it cool: The sugar free condensed milk will still be quite liquidy when it’s warm. Do not despair, and do not panic and add more thickener. It will continue to thicken up as it cools. If it doesn’t, bring it back to a simmer and then whisk in another ⅛ teaspoon xanthan gum.
Dairy-Free Option: You can make this just as easily with full fat coconut milk. I don’t recommend replacing the butter with coconut oil, as it doesn’t blend in as well. But you can cook it a bit longer and add a touch more xanthan gum to help thicken it up properly.

Once you make the condensed milk, let it cool to room temperature. Then transfer to a jar or resealable container and store in the refrigerator. It will last for up to two weeks in the refrigerator as long as your cream was fresh.

norma says
can you replace unsweeted condensed milk with heavy cream in the magic bar
Carolyn says
Nope. What a disaster that would be. Not thick enough and you’d have a mess on your hands.
Diana says
How many ounces does this recipe come out to because I’m trying to make a another candy recipe using your sugar, free condensed milk and the recipe calls for 14 ounces that’s the size of a typical condensed milk can.
Carolyn says
Easy to figure out. This makes about 1 cup, so 16 tbsp or 8 ounces.
