I remember the first time I heard about making dulce de leche from sweetened condensed milk in the can. I know you all have probably heard of it; put a can of unopened sweetened condensed milk in a pan, cover with water and simmer for 3 hours. Of course I had to try it. That was absolutely mandatory. I was blown away by the thick, sweet, utterly perfect caramel that came from such a lazy cooking method. Score and a half!
As time went on, I had a couple of concerns pop into my head about this method. There were people who had experienced exploding cans while simmering. Whether the water level had dropped too low or the pressure had been to great in the can or whatever, the fact remained that those cans EXPLODED. Eek. And as I gave it more thought, I was more than just a little bit concerned that whatever the lining of the can, it wasn’t intended as a long, slow-cooking vessel and might be leeching unpleasant things into my lovely caramel. The draw of making caramel that easily was pretty hard to resist, though, so I decided to make one using the same methodology, minus the very real explosive and less clear chemical risks…
I realized that there was an additional advantage to taking out and re-housing the contents of the cans of sweetened condensed milk beyond the lack of potential shrapnel and chemical mutation; I could infuse my caramel with flavours. I started with today’s variation and simply split and scraped a vanilla bean into each jar before filling with regular old sweetened condensed milk. A lid was screwed in place, the jars were positioned in my slow-cooker, water was poured to cover the jars by an inch, the lid was popped into place and the whole shebang cooked for 8 hours on low while I slept. When I turned off the slow cooker in the morning, I removed the lid and let the jars rest in the water until it returned to room temperature. A couple of hours later, when I could comfortably stick my hands into the water to pull out the jars (because you can be darned sure I wasn’t experimenting with one dinky little jar of heavenly dulce de leche. Go BIG!) I was rewarded by seeing a gorgeous brown Slow-Cooker No-Stir Dulce de Leche inside the jars.
I stuffed two jars (like I said, GO BIG!) in the refrigerator and opened the remaining jar to sample my wares. Perfect, thick, luscious, velvety, caramel was my reward. The boys grabbed from our freshly acquired bushel of Western New York’s best fall apples, I sliced, and we all dipped and dunked Slow-Cooker No-Stir Dulce de Leche until we couldn’t any more. Even the no fruit twosome happily put aside their usual aversions to lick vanilla-scented, creamy caramel from crisp apple slices.
Is this the perfect caramel apple dip? Oh my, yes. Don’t forget, though, that it’s also wonderful in ANY dessert calling for caramel or dulce de leche. Use as a filler between cake layers, cookies, on ice cream, stirred into hot chai or coffee or cocoa, or simply convey to mouth with spoon; whichever way you eat it, you’ll be so glad you did!
Cook’s Notes
- Yes… This is safer than cooking in a can. Why? A) a can is lined with a substance designed to keep the contents from reacting with the metal of the can, but that lining also contains chemicals that aren’t meant to be heated for long, long periods of time like you do when you make dulce de leche IN the can. Besides that, B) Most canners will tell you that when a jar breaks, the bottom breaks away and things slowly bubble and ooze out into the water around the jar. Is that a bummer? Heck yes, but it’s a lot safer than the contents of a sealed can pressurizing and going KABLOOEY! I’ll take my chances with the jar that has a couple of week points that are almost like safeguards.
- I mentioned the infusion of the Slow-Cooker No-Stir Dulce de Leche with different flavours. I used a vanilla bean for my recipe, but I can imagine a tablespoon of bourbon or rum wouldn’t be misplaced here, either! Maybe some cardamom or cinnamon? Go wild! Tell me what you do with YOUR Slow-Cooker No-Stir Dulce de Leche!
- If you leave the lid on the jar, rinse it to clean it, and pop it straight into the refrigerator, this caramel should keep well for at least two weeks. I have not tried freezing it, so I can’t speak to whether it stores well that way. Educated guesswork tells me that you’d probably want to scoop some out (directly into mouth, if you’re wise) before freezing to allow room for expansion. If you try, do let me know how it works for you!

- 1 can sweetened condensed milk 14-16 ounces
- 1 half of a vanilla bean split and scraped, seeds and pod reserved
- 1 pinch salt
- 1 pint sized canning jar with a clean two-piece lid
Additional equipment needed:

Instructions
- Add the split and scraped vanilla pod and seeds to a clean pint canning jar. Open the can of sweetened condensed milk and pour it into the jar, scraping the can to be sure to get all of the sweetened condensed milk. Add the pinch of salt. Screw the lid in place to fingertip tightness, then slowly invert and turn the jar right-side-up several times. Put the jar(s) in the slow-cooker and add hot tap water to the slow-cooker to cover the jars by an inch. Place the lid on the slow-cooker, set to LOW and let it cook for 8 to 12 hours.

Reader's Thoughts...
Nancy Jacob says
Has anyone tried doing this using a water bath canner instead of a crockpot? Would it be shelf stable or only refrigerated? I wish it would last longer than 2 weeks so I could make more jars at one time.
Rebecca says
Hi Nancy- I would definitely not consider these shelf stable after making it. It’s too thick to be considered safe for home canning, unfortunately. 🙂
Mandy says
I’m sorry, I’m very much a visual learner and I’m struggling with the “turn the jars right side up” part
What does this mean?
Thank you🙏
Rebecca says
No worries, Mandy!! What you want to do is turn the jar upside down (ring/lid facing the floor) then back right side up (ring/lid facing the ceiling) several times.
Mandy says
Thank you for clarifying 🙏❤️ this recipe is amazing!!!
Rebecca says
You’re very welcome, Mandy! Thanks for taking the time to rate the recipe and let me know you love it!
Elizabeth says
can u use 4 ounce jars instead of 8 ounce?
would the cooking time change?
Rebecca says
Hi Elizabeth- I’m certain you can use 4 ounce jars, but I only tested it in the 8 ounce ones, so I’m not sure what -if any- change would be needed in timing. 🙂
Darla says
I have made this before but couldn’t remember time or how much water. For those worried about the jars, they are made to take heat for long periods. I do a lot of canning and have never lost a jar in my water bath canner or pressure canner. I know what’s going in my crockpot tomorrow. Thanks for the recipe.
Rebecca says
You’re very welcome, Darla! I’m so glad you love it!
Sally says
This sounds delicious. What type of canning jar do you use?
Rebecca says
Hi Sally- I use 8 ounce jelly jars. 🙂 I’m glad you think it sounds good. 🙂
D Brock says
I tried this yesterday and it is sooooo good. I will never buy Carmel dipping sauce
For apples again! Also am thinking of all the recipes that this would work with..
This recipe is a forever keeper. Thanks
Rebecca says
That’s awesome, D! I’m so glad you loved it!
Kimberly says
Question: I am going to be making this the day before I need it. How do I store it to use it the next day? (it will be a filling a drip on a cake) Thanks. And if it’s refrigerated, will it get hard?
Rebecca says
Hi Kimberly- Store it in the refrigerator! And it will firm up some, but you can definitely loosen it back up by warming the jar gently in a pan of hot water and stirring from time to time.
MaryLee says
When you say “cover the jars by an inch” with water, do you mean only an inch from the bottom of the jar or fill the crockpot with water that’s an inch away from the top of the jars? I’d love to make some this Christmas season!
Rebecca says
Hi MaryLee- You definitely want the water to cover the top of the jars by an inch. Merry Christmas!
Sheryl says
Hi Rebecca!
I’m wondering if the milk should be leaking into the hot water. I’ve had my jar of milk in my slow cooker for an hour and a half. It’s laying on its side so that it will be covered with water. I just peeked at it and some of the milk is leaking into the water. It is not a two-piece lid but it’s One that has a gasket inside the lid. I tightened it a little more but I’m kind of nervous about that.
Rebecca says
Hi Sheryl- You don’t really need to WORRY, per se, but they likely leaking because they are on their sides with 2-piece lids. They really should be upright. It’s not the end of the world, though, it may still work out for you. I would put them upright if possible. 🙂
