The easiest ever slow cooker (crockpot) home made condensed milk caramel sauce, made without cream or fuss. Perfectly smooth, not grainy, slow cooker caramel!

Do you know that feeling, when you realise that you’ve somehow acquired a dreadful new habit? One that has appeared from nowhere but is almost impossible to shake off?
The other night (morning) as I put my iPhone down at 1am to go to sleep, I realised that yet a-bloody-gain I’d been suckered in to the time sapping vortex that is Pinterest. I often feel like I’ve got no time to finish the jobs I want to, you know, all of the important stuff like having my eyebrows threaded and reorganising my stash of greetings cards. It turns out that perhaps I know where my time is going.

But honestly, how can you argue with pure genius like this? This is slow cooker (or crock pot if you fancy) condensed milk caramel. It’s all over Pinterest, all of the cool kids are doing it.
So today I’m not showing you anything new, but as I’m planning on using this crockpot condensed milk caramel in a couple of cakes I thought I’d share a few of my tips for making it.

The general idea for this slow cooker caramel is an unopened tin can of sweetened condensed milk, cooked slowly until it turns to caramel. Yes, it’s actual, bone fide magic! You don’t need to use a slow cooker (or crockpot). Word on the street is that you can boil the cans on a very low heat on the hob for 2 – 3 hours for the same effect.
Tips for making the Slow Cooker Caramel:
- If you cook the cans of sweetened condensed milk in your slow cooker, put a sheet of baking paper inside the bowl under the cans so that they don’t mark the pot.
- If you cook this in the unopened cans, once you’ve done the cooking and cooling process, you can store the unopened cans of slow cooker caramel at room temperature indefinitely.
- The only problem with cooking it in the cans is you can’t see when the caramel is made, as all slow cookers vary in temperature, this does take a bit of practise. Mine takes 8 hours on high but yours might take less time if it’s newer than my old relic.
- It is possible to over-cook the caramel. It becomes very firm. Even then, if you warm it up a little in a pan or the microwave, it will soften for spreading on cakes or pouring.
- You can choose to decant the condensed milk into sealable, watertight jars before cooking in the crock pot. The benefit to this is that you can see when the caramel is made. The negative is that you can’t store it at room temperature, unopened like you can with the cans.
- Try adding sea salt flakes (before if decanting into jars to cook, or after if cooking in the cans) for condensed milk salted caramel sauce, oh YES.
- Don’t open the cans until they are cold. I’m not sure why, but I found when I was a bit eager to open them the texture of the caramel was grainy (and stayed that way) compared to the super smooth cooled caramel.
- Make sure it’s “condensed” milk, not “evaporated”, they don’t work in the same way.
- I use this condensed milk (available from Amazon) and these pretty 324ml jars (also on Amazon).
- Through all my obsessive Pinterest research on this caramel, I can’t seem to find a definitive answer as to how long it lasts once the can is opened. General consensus seems to be 2 weeks in the fridge, although I haven’t tested this. I would love to say I will do and report back, but it doesn’t seem to last that long before being eaten. Oops.
Things I used to make the condensed milk caramel sauce:
NB! All of the tins say “don’t boil unopened” in case the can explodes.. Please don’t shout at me if for some crazy reason your can explodes. I’ve done this a lot of times and have never had one explode or heard of one explode. Please just be careful, make sure the pan doesn’t boil dry and the can is fully covered and use your lowest slow cooker setting, building it up gradually if it’s not well cooked enough.

You can also cook the unopen tins in a pressure cooker for 45 minutes. You have to wait until it cools down cause the caramel inside is very liquid while hot and will spray out of the can…
Thanks Cintia! Great tip.
This is how I was taught years ago! For a quick version, 1 cup brown sugar and 1 stick butter brought to a low boil for 5 mins.. pour over your dessert.
This kind of thing makes me drool! But what do you do with it? I guess its the base of a banoffee pie…what else? I’d be afraid that I’d just eat the whole lot myself while noone else was looking! #tastytuesdays
Hi Sam, you can use it to sandwich cakes, stir through icing, use as a sauce, as you say, in banoffee pie, dollops in cookies, ice cream, or cakes… Too many options!
Pour in a gram cracker crust and chill it makes a great caramel pie
This is what me and my family have been doing with the prepared caramel… After its chilled in fridge open BOTHE ends of the can and push the caramel out onto a plate… Like you would with canned cranberry sauce put a piece of sliced pinaple then a slice of the caramel then some whip and a marichino cherry or ten…lol however many you like anyway.,my Grammy called it caramel salad. The combination of the pineapple and caramel is off the chart delicious.
Yes, the caramel salad was served to me as a teen by my boyfriend’s Mom. I’ve never forgotten how amazingly good this was. 50 years ago, I should add. So glad someone has finally explained how she made it!
Do you realise how utterly delicious/dreamy/lick the screen stunning this post is? My favourite of yours I think! Wow, wow, wow! LOVE! Thanks for linking up to

When I was a kid my Nan and also my Mum used to boil the cans for 3 hours to make the caramel. It never failed. Although there were some grainy ones like you mentioned. Maybe they were opened while still warm.
I’ve boiled the cans myself too (although now you can buy it already done – it’s called Top ‘N’ Fill). It doesn’t last very long once it’s opened . . . because I can’t stop eating it!!! Mum also used to mix a little bit of lemon juice through the caramel before adding it to tarts, which always tasted pretty good.
In England we use this in a shortcrust pastry case and it is known as Gypsy Tart, a favourite from schooldays.
I made this as a gift to give away at Christmas with a little “tweaking” i found this amazing and it tastes great over Cheesecake ^_^
No, gypsy tart is made with whisked evaporated milk and muscovado sugar, but it is equally delicious as a pie filling.
Why have I not seen this before?!? This looks amazing, I am definitely trying this out as we are a little bit slow cooker mad in our house. Are those “Bonne Maman” jars I recognise in the photo?
I wouldn’t do this….I just tried it today and my crock-pot lid shattered 4.5 hours in. Tiny shards of glass all over the kitchen and my lovely crock-pot it ruined 🙁
Sorry to hear that Raquel, how odd! I wonder why that happened as it’s no different to cooking anything else in it, the cans exploding are normally a worry but not the lid?
It is recommended that you use a completely sealed can and not one of those with the pull top lids. Just in case that was the reason. We’ve done 8 of these and had no issues so far. Sorry this happened to you, hope no one got hurt. I love learning things like this as a group, so we can all be safe.
i used the pull off top lids in my pioneer woman crockpot , 3 cans with about an inch of water above em and the lid on and had no problems although i think i cooked them too long bc they are really dark
That looks and sounds amazing. I’m actually drooling whilst I read this on the train (which may also mean I get a double seat to myself…) Great post and great recipe 🙂
Looks really yummy, maybe I should dig out my slow cooker.
Looks so good I might have a go. I like your joke about it lasting 2 weeks,… as if.
