1-Ingredient Slow Cooker Caramel Recipe

Prep Time 5 mins
Cook Time 3 hrs
Cook Time Maximum 8 hrs
Total Time 3 hrs 5 mins


  • 1 can sweetened condensed milk


  • Place unopened can on dish in crockpot to prevent rust stains from getting on the bottom of your crockpot; I used a glass bread pan.
  • Put enough water in the crockpot to cover the can.
  • Turn the crockpot on low; cover. Let cook for 3-8 hours in the crockpot. I let ours go closer to the 8 hour mark.


As you can see in the last picture, the can definitely left a rust ring on the glass, and even that took some scrubbing to get off. Make sure you put the can on something so it won’t stain your crockpot. I tried two different brands of sweetened condensed milk, just to see if there was a difference. The consistency of Nestle Carnation was very smooth, just like what I was expecting. I also tried Eagle Brand and it was more the consistency of sour cream, but the taste itself was similar.
