I once made an upside down peach cake with a caramel glaze. It was AMAZING, and I lost the recipe. I tried searching high and low, but the internet is a vast place, and I couldn't remember the exact keywords I used when I found 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. 

When I was getting this post together, I wanted to try out the 'one ingredient caramel sauce' recipe I had seen floating around on Pinterest, but when I looked into my pantry, I discovered that the sweetened condensed milk I had was actually evaporated milk, and expired in 2012. So I had to put my experiment on the backburner. That is, until now!

I was excited when I actually remembered to buy sweetened condensed milk (not usually on my list) at the grocery store earlier this week! As soon as I got home, I whipped out my weck jars and crockpot, and immediately tried out the one-ingredient recipe.

I was pretty skeptical, of this recipe, 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 swearing, no temperature taking; just waiting! 

As I've done further 'research', you can definitely 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".

Crockpot Caramel Sauce "Dulce de Leche"


  • Sweetened Condensed Milk

How to:

  • Fill clean jelly jars with sweetened condensed milk, leaving 1/4" head space. 
  • Seal with a lid, and place into crockpot. 
  • Fill 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 sugary goodness!
