This sugar free condensed milk is an easy replacement you can make in 30 minutes using only three ingredients! Now you can enjoy all your favorite recipes that call for sweetened condensed milk, from pies to fudge to homemade ice cream.
Traditional home bakers have it easy. If they want to make homemade fudge, easy ice cream or pies, they can simply open a can of sweetened condensed milk from the grocery store. But if you’re eating low carb, there isn’t a ready-made option to buy.

Instead, I make my own sugar free condensed milk when I want confection favorites like homemade caramels or key lime pie.
Store-bought sweetened condensed milk brands can contain corn syrup, sugar, milk solids or vegetable oils. This version of thick, creamy sweetened milk suddenly doesn’t sound appealing.
It’s easy to make and you don’t have to spend hours in the kitchen or buy expensive ingredients. All you need is butter, sugar-free sweetener and heavy cream or ultra-filtered whole milk. That’s it! Once it thickens up in the refrigerator, it becomes that irresistible, caramel-colored sweetened cream perfect for pies, tarts, and cheesecakes that adds incredible richness and creaminess to the filling. Or try it in your coffee or tea for a creamy, indulgent treat!
KetoFocus fans think it’s the BEST!!
“I actually made this a few weeks ago. To be honest, I don’t even remember why I made it. I was going to use it for some recipe I didn’t end up making. Yet it was so freaking good I ended up eating it on other things. It’s awesome on keto toast, on blueberries, or to be perfectly honest, it’s nearly impossible to not just shovel spoonfulls right into your mouth, it’s that freakin good. Mine only lasted about 4 days in the fridge before it was all gone.”

“I make this milk all the time. Love it! I make coconut candy with almonds and a drizzle of chocolate on top using unsweetened coconut milk. It’s so good.”

How to make sugar free condensed milk
Besides only using three ingredients, this homemade condensed milk recipe is made in one pot. I add all the ingredients at once and walk away. No constant stirring required.
- Add ingredients – Add unsalted butter, powdered sugar-free sweetener and whole milk or heavy whipping cream to a medium saucepan.
- Heat mixture over medium heat until mixture boils.
- Reduce heat to low and simmer over the stovetop for about 25-30 minutes or until the mixture thickens.
- To thicken – Remove from heat. Pour into a mason jar or storage container. Let sit at room temperature for 30 minutes to cool before transferring to the refrigerator to thicken for 2 hours.
Key ingredients & substitutions
- Butter – Unsalted butter is best as salt isn’t necessary in sweetened condensed milk. Since this thick, creamy milk is used to sweeten candies and cream, add salt to that recipe instead of the condensed milk. This way you can control the level of saltiness.
- Sugar free sweetener – Use powdered sweetener as it dissolves easily into the mixture. Allulose is the preferred sugar-free sweetener as it doesn’t crystalize when it cools unlike powder sweeteners made with erythritol.
- Milk or cream – For the lowest sugar whole milk, look for one that is ultra-filtered which means that most of the natural lactose sugars have been removed. Fairlife milk is ultrafiltered and has 6 grams of carbs per cup. If using whole milk, add 1/3 cup of heavy cream to the mixture so the condensed milk cooks quickly without scorching. Heavy whipping cream is another option. This increases the fat content and still contains carbs. Since 1 tablespoon of heavy whipping cream contains 0.3 g carbs, one cup of heavy cream has 4.8 g carbs. Canned coconut milk is the best substitute for a dairy free condensed milk.

2 cups heavy whipping cream or ultra-filtered whole milk
Step by Step Instructions
Step by Step Instructions
Bring to a boil
Add butter, sweetener and milk or cream to a heavy bottom saucepan. Bring to a boil over medium heat while stirring occasionally.
Simmer until thickened
Reduce heat to low and simmer the mixture for 25-30 minutes or until the mixture has thickened and can coat the back of a spoon.
Refrigerate
Remove from the heat and pour into a storage container or mason jar. Let cool at room temperature for 30 minutes before transferring the keto condensed milk to the refrigerator to cool for 2 hours. Mixture will thicken as it cools. If mixture appears chunky, strain through a wire mesh first.

Can I substitute granulated sugar free sweetener with the powdered sweetener?
When it comes to sugar free sweeteners, some won't dissolve when mixed or heated. To avoid making your homemade sweetened condensed milk grainy, use a powdered or confectioner's sweetener.
Can I use low-fat milk instead of whole milk?
Low fat milk is higher in sugar compared to whole milk or cream. If you want the lowest sugar condensed milk, use whole milk. Unless you are able to find a low-fat milk that is ultrafiltered to remove some of the sugars, like FairLife Fat-Free Milk which contains only 6 g sugars per cup.
What's the difference between condensed milk and evaporated milk?
The main difference between condensed milk and evaporated milk is the amount of sugar they contain. Condensed milk is sweetened with sugar, while evaporated milk is unsweetened. Condensed milk is also thicker since it contains less water.


This is probably my fifth batch and I think I finally cracked it (took me a while). The first few times I used heavy cream and it worked but came out so thick I had to thin it down when mixing it into things. Switched to the ultra-filtered milk and it's actually more versatile for me, mixes into batters without clumping or separating. I also started pulling mine at 28 minutes instead of 30 because it was getting a little darker at the edges on my stovetop and the texture was better slightly earlier. The other thing I noticed is it firms up a lot more in the fridge than it looks like it will in the pan, so if it seems a little loose when you pour it out that's probably fine. I keep a jar in the fridge now and pulled it out last week to make a fudge and it worked exactly like I hoped.
I used to make key lime pie every summer with a can of condensed milk and it was one of the first things I missed going keto. Tried this batch last week and it thickened up nicely at about 27 minutes. First key lime pie in two years is happening this weekend.
27 minutes is right in range. Key lime pie coming back after two years is a big deal. Post back after the weekend.
Made this last week for the first time and it came out really well, but I'm still not sure when to pull it. Mine went about 28 minutes, still looked pretty thin in the pan, then thickened up once it hit the fridge. Is that normal, or should it be visibly thickening on the stove before I take it off? Just want to know what to look for so I'm not standing there guessing next time.
That's normal. It won't look thick coming off the stove, the fridge finishes the job. On the stove you're just watching for volume reduction, roughly half of what you started with, and it should coat the back of a spoon. Run your finger across and if the line holds, pull it.
Didn't think this would work but it did. Used the heavy cream version and it thickened up just like it's supposed to.
The cream version is way more forgiving. I use it for fudge because it thickens faster and doesn't need as much stirring.
I tried this but using a microwave. I followed the microwave directions in the video
"Ultimate Clotted Cream - From Any Cream In 15 Minutes" but with these ingredients. It worked quite well. I did go past sweetened condensed milk stage to make a keto dulce de leche using allulose. I did get splatter on the 3rd 5-min heating. I then did a 4th 5-min at 80%(to limit splatter) for the dulce de leche.
You use a wide pan (such as 8x8 glass pan) no more than 1/3rd full. Careful to use a spatula to disturb/stir after microwaving to safely release the superheated spots that will boil up on you if you disturb the pan by lifting it.
Going past condensed milk to make dulce de leche is clever. Allulose is the only sweetener that caramelizes so that was the right pick. That superheating thing is real, I've been caught by it stirring too fast.
I have that exact same spoon
Ha, that spoon has been in more videos than I can count.
This looks wonderful and I'm excited to try it. However, under the dairy free directions, you still add butter, which means it isn't dairy free. Would ghee and coconut cream work for this? Or butter flavored coconut oil? Just wondering if you've tried either of those?
Thank you for all the work you put into your videos for all of us.
Oops that was a typo. Yes, use ghee.
