This homemade caramel sauce, or "Dulce de Leche", only requires one ingredient & a crockpot!
I once made an upside down peach cake with a caramel glaze. It was AMAZING, and I lost the recipe. I spent hours searching for that recipe, but the internet is a vast place, and I never did find it. I will forever be trying to recreate that cake, but one thing I do remember about it, is that making caramel sauce is a lot easier than one would expect. I didn't have to use a candy thermometer, and I didn't burn myself - two things I was sure would happen when making caramel.
I have seen this sweetened condensed milk recipe on Pinterest multiple times, but I have always been weary of it. Primarily because of the heat & tin can situation. I've read how toxic the lining of cans can be, one would think that adding heat is a recipe for disaster. When I discovered you could make this caramel sauce in glass jars, I was sold on giving it a try.
I was pretty skeptical, but to my surprise - it turned out! After simmering in the crockpot for 8 hours, I had 3 jars of perfectly colored caramel. No burning, no temperature taking; just waiting!
As I've done further research, you can absolutely spice and flavor the milk prior to adding it to the jars. Try adding some vanilla, sea salt, cinnamon, or pumpkin spices - they will all be delicious! And, if you're wondering if this is shelf stable, the verdict is still out.
I've read some posts saying that it is, and some saying that it isn't. Like I said before, the internet is a vast place, and you can't always believe what you read. There really isn't any reason that these wouldn't be shelf stable, but it's probably your best bet to keep them refrigerated. With that said, the internet does agree on one thing: refrigerated, these will last for "forever".
This is the world's easiest caramel sauce, and probably the most inexpensive. I've included a free printable that is compatible with these stickers so that you can give this caramel sauce as a gift!

Crockpot Caramel Sauce "Dulce de Leche"
- Sweetened Condensed Milk
- Fill clean jelly jars with sweetened condensed milk, leaving 1/4" head space.
- Seal with a lid, and place into a crockpot.
- Fill the crockpot with water, so that the water covers with jelly jars by at least 1".
- Cook on low for 8 hours.
Using glass jars, whether Weck or not, eliminates the worry of BPA toxins leaking into the caramel sauce, plus it's prettier.
