How to make lactose free condensed milk


Condensed milk has been a bit of a cooking thorn in my side since getting into FODMAP. Given that, as the name suggests, it is condensed dairy, it tends to be very high FODMAP. While I personally seem to have grown out of my lactose intolerance, the sheer amount of lactose in condensed milk gets to me. So, we’re out here making lactose free condensed milk.


Fair shout. You might not have come across too many recipes that require it. Things like no-churn ice cream (great for people without an ice cream machine) and caramel slices often ask for condensed milk. I am also in the process of using it for a banoffee pie recipe, which is coming soon.

I have a recipe for caramel slice in my cookbook, although the editing process didn’t allow me a full low-down on the stages of condensed milk making, which I will include here. It also concluded in calling for ‘full cream’ instead of ‘full cream milk.’ Yikes!

A vegan, and thus lactose free condensed milk is next on my agenda. I haven’t tried it yet, although I do have a can in my pantry, so I know it’s possible. Keep in mind that it requires a lot of milk to be condensed, so milks like soy are probably not a great idea for FODMAP people, despite their creaminess.

I fully intend to update this with some more milk options ASAP. Keep your eyes peeled.


I initially intended to use brown sugar for this recipe – I love the caramel flavour it brings to baked goods. I’m not a huge proponent of excessive added sugar in recipes, and brown sugar ensures bang for buck – it lends sweetness and caramel tones.

THAT SAID, I had very mixed results from testing with brown sugar. Given brown sugar contains more liquid and is subject to more changes in liquid volume than caster sugar, it is really difficult to predict results. Don’t quote me on the science, but trust me on the unpredictable results. And trust me again when I say that there is nothing more heartbreaking than ruining an entire litre of milk that you’ve spent an hour cooking.

I would like to try a version with maple syrup and I’ll report back when I do.

Lactose free condensed milk

A quick and easy way to make condensed milk with lactose free milk. Makes approximately 1 3/4 cups of condensed milk.
4.75 from 4
Prep Time 5 mins
Cook Time 1 hr 30 mins
Total Time 1 hr 35 mins


  • 4 cups full cream lactose free milk
  • 1 2/3 cup caster sugar


  • Combine the lactose free milk and sugar in a medium, heavy bottom saucepan. Place it over a low heat. I'd recommend using the smallest burner you have - I have found that is the easiest way to ensure you don't end up with burnt or curdled condensed milk. 
  • Cook over this low heat, stirring intermittently, for at least an hour. During this time, it will gradually turn a blue grey colour, before eventually turning a golden brown, as per the photo. 
  • If at any time the milk is burning to the bottom of the pan, or the mixture is bubbling wildly, lower the heat. Slow and steady!
  • The condensed milk is ready when it can lightly coat the back of a spoon, and is still thin but more viscous than at the beginning. It will thicken considerably once cooled. 
  • Store in an airtight container in the fridge, and use for anything from no churn ice cream to caramel slices to Vietnamese iced coffees.

Condensed milk is truly a game of patience. Before writing my cookbook, I was trawling the internet to find out if it could even be done. I came across an article which was very helpful (video included) but had comment after comment regarding failed condensed milk.

The trick, I have discovered, is low and slow. That’s literally the only trick. If an article says you should have condensed milk in an hour, take it with a grain of salt. You are much better off using the smallest burner on a low-medium heat, and letting it do it’s thing. If you panic and turn the heat up, chances are you’ll end up a grainy pot of condensed milk.  Not the end of the world, but not ideal.

I like to make my lactose free condensed milk when I’m pottering around at home. I place it in a large saucepan (although I have also had success doing it in my skillet) and I always put it on the smallest burner at a low setting. Every time I think of it (increasing in regularity with time) I stir the condensed milk as I walk past. No stress, no fuss!

The milk will go through stages. First, it might do nothing. Then, it might turn a little grey in colour. Next, it will gradually start browning, and it might look ‘fluffy’ or start to boil. It should only ever be JUST bubbling. Faint, occasional bubbles at best, Once it can coat the back of a spoon, you are done, my friend. Don’t delay in taking it off the heat if you’re worried – you can cook it a little more later, but you can’t un-cook it, ya feel. I was trying to think of a good consistency to compare it to – regular condensed milk. Compare it to regular condensed milk.


As I mentioned before, the condensed milk is done when it can comfortably coat the back of the spoon. I’m unsure whether this is something to with homemade condensed milk or the lack of lactose, but my condensed milk is considerably more golden in colour than the supermarket variety. It is basically the appearance of a runny caramel. Don’t stress if yours is lighter, but probably stress a little if yours is darker. Aka, burnt.

    I’ve just purchased lactose free condensed milk in Lanzarote. it’s made by Nutricia and lablled “sin lactosa”

  2. Hi there! Is there a particular brand that makes full cream lactose free milk? I’ve never heard of it before. Could I use whole milk that is non-dairy?

    1. Hi Anthony. I’m not sure where you live but here in Australia there are lots of brands that do full cream lactose free milk – Liddells, Pauls Zymil etc. You could try with a plant based milk but I’d recommend googling a vegan recipe because the quantities are probably quite different

    1. To be honest I have absolutely zero experience with slow cookers (never used one) so I can’t really say I’m sorry. If you try it let me know how it goes!

  3. Hi Georgia! I’ll make this tomorrow morning as part of a lactose free ice cream I’m doing for my daughter. I just wanted to say thank you, it’s been a real journey buying and making foods to accomodate my daughters lactose intolerance so I love seeing people like you out here spreading awesome recipes! Thanks!

    1. Hi Rick, I’m really glad to hear that you are finding the recipes useful! I hope your daughter enjoys the ice cream too, nothing beats homemade ice cream 🙂

    2. I am Italian and being lactose intolerant is very difficult when eating out and making recipes.

  4. Hi, looking to try this out but needing a much smaller quantity for my recipe (obviously I can just half quantities etc) but have you tried storing the condensed milk after it’s been made? Thanks!

    1. Hi Laura, it keeps really well in an airtight container in the fridge for a decent amount of time. I’d say a couple of weeks would be a conservative suggestion. I haven’t tried it, but some regular condensed milk recipes suggest you can also freeze it for a few months with no issue 🙂

    JTLYK that Nestle makes a lactose free sweetened condensed milk, though it’s difficult to buy because it sells out in a flash at the grocery markets. It’s also irregularly sold on amazon, for 5-6X more than at the grocery market. Guess what? It’s color is considerably darker than Nestle’s regular sweetened condensed milk. Thanks for sharing your recipe. I will try making it with a non-sugar sweetener, since sugar seems to aggravate my autoimmune disease.
