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.

Eeh Bah Mum says
Looks so good I might have a go. I like your joke about it lasting 2 weeks,… as if.
Julie's Family Kitchen says
Looks really yummy, maybe I should dig out my slow cooker.
Jonny Dockett says
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 🙂
Sophie at Franglaise Cooking says
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?
Raquel says
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 🙁
Sarah Barnes says
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?
Donovan says
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.
GwennieL says
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
Jenni says
In England we use this in a shortcrust pastry case and it is known as Gypsy Tart, a favourite from schooldays.
Valerie says
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 ^_^
Nicole says
No, gypsy tart is made with whisked evaporated milk and muscovado sugar, but it is equally delicious as a pie filling.
Sue H says
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.
Honest Mum says
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

Sam says
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
Sarah Barnes says
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!
Kelly ward says
Pour in a gram cracker crust and chill it makes a great caramel pie
Charmaine says
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.
Kim says
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!
Sherryl @ SimplySherryl says
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.
Cintia says
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…
Sarah Barnes says
Thanks Cintia! Great tip.
Sarah, Maison Cupcake says
I am so doing this soon. Just been assembing my Babycentre slow cooker post and this was perfect for the dessert section – thanks for suggesting it.
Corinne says
I usually boil 4 tins at a time and they keep for months unopened, perfect for when we fancy a banoffi pie!
Eleni says
That is why I looked this up! I am making Banoffee cupcakes!
Kelly Barnett says
OY MY! I made this overnight in the slow cooked – AMAZING – perfect way to start a Sunday morning on pancakes mmmmmmmmmm……
Meagan Ellenberger says
Does the cool time vary when using fat free condensed milk?
Donna says
Oh my gosh. Oh my gosh! You are my foodie god! x
Nadya says
I have done this since I was a kid 🙂
It is very important that water covers the top of the cans by at least 2″. As soon as water level gets down close to the top of the can or below it, this is when you risk the can explosion happening.
Charis Bautista says
Hi! My mom and I tried this, we just boiled 2 tins of condensed milk for 2 hours, and it came out great. 🙂 I’d want to ask if anybody tried making salted caramel from it though. How much salt should I use?
Craig says
Have been doing this on stove for 20 odd years. Caramel tarts! Mmmmm. Note: keep water level above tin or pressure difference will make it pop, & opening can too hot and pressure will fire caramel out like hose(3 degree burn HOT).
Gwen says
My daughter wants to dip apples to take to school. After dipping will the apples have to remain refrigerated? They will be out all day.
Kara says
Oh my, this looks pure amazing xx
Keri says
Yum!
When I was about 6 in the 80’s a neighbour friend would boil tins in a pot on her stove….and yes, I have very vivid memories of a can exploding! It went EVERYWHERE….ceiling included! The stories are true. Make sure it stays covered in water no matter how you go about cooking it. Unless you fancy repainting your kitchen….
Johna says
Thank you for this post! I plan on using this caramel saucefor wedding favors. Yours was the first thar had the answer I was looking for “is it shelf stable if made in the can?” I have roughly 100 cans to make and storing them in the fridge just isn’t possible. Now I can start making them for my October wedding. Thanks again 🙂
C.A.W. says
I stir in 1/2-1 t. pure vanilla extract OR butter-nut flavored vanilla extract. Depth of flavor…
Nicole says
Does the slow cooker have to be set to high for this to work? I only have 2 setting on my slow cooker – high and low, and I have seen other recipes where the temperature is set to low.
Joyce says
I don’t understand why it isn’t stable in the jars since they are sealed.
Jeff says
Can you over cook it. It says 8 to 10 hours but I forgot about it and it was in for 25 hours lol its real dark brown and like jelly. Don’t taste to hot either
Sarah Barnes says
Hi Jeff, oops! I think it may well be overcooked! Especially if it doesn’t taste good. Perhaps try again?!
món ngon mỗi ngày says
It tastes really good.
Cara says
I’m going to be really thick now and ask do I have to add syrup or anything to make it taste like caramel? Is it because it’s in the slow cooker it tastes of caramel I’m confused
Sarah Barnes says
It’s the cooking for hours that makes it turn into caramel 🙂
Missy says
My grandmother made this on the stovetop probably 45 years ago and served it at a family dinner, like maybe Easter. She intentionally cooked it until it was “hard” (no longer a sauce, but not really hard at all).
As I remember, she chilled the can after the cooking, and when she served it she opened both ends of the can and used the bottom as a “pusher.” She pushed up about a half inch and sliced the round onto a dessert plate and topped it with a scoop of vanilla ice cream. I still remember it all these decades later – it was that good!
I was just gifted a can; that’s what made me come look for the recipe. Luckily, it’s not a ring-pull top so I am going to try it in my mini-crockpot.
Tracey Hall says
Remember my mum doing this in a pressurer cooker in the 70’s, loved it after it became cool.
Levi Armstrong says
I like your advice about adding sea salt flakes to get a condensed milk salted caramel sauce. My children would love this since they all have sweet tooths. My sister and I plan to make some this weekend, so I’ll buy some milk caramel on my grocery run tomorrow. Thanks.
Elaine says
I remember my mother making this by putting the tin in the copper to boil away with the clothes on washing day. No extra power needed to make it. This would have been 75-80 years ago when I first remember it & she continued to do this until she got her first washing machine.
Sarah Barnes says
Wow what a super memory Elaine!
Jackie says
Just heard about this recently, only have a small 1.5 qt crockpot and it’s only been used once before. (have s sign in my kitchen that reads: I know how to cook, i just don;t) but wanted to try it and seemed like a fun experiment. Am a night owl so put it in the crockpot on the lowest temp, covered it with water to the top about 5:30 pm expecting to take it out at 1:30am. Forgot and didn’t notice it until about noon the next day. Wa nervous about what I was going to find, but when I opened it it was perfect! Creamy, not too thick, but needs to be thinned if used as a sauce. Licking some off my finger right now….
