No more worries about popping pressurized cans or watching the stove for hours on end. Let your slow cooker turn sweetened condensed milk into this decadent foolproof dulce de leche.

I have made this recipe as written, until I found out it is unsafe. Making this recipe as written left me with rust rings on the bottom of my crock pot, and after doing more research, I would never feed the finished product to my family again. It is unsafe to make dulce de leche in the can. Heating the can for long periods of time releases chemicals. (it clearly is labeled on any sweetened condensed milk can "Do not heat in can" for this reason) This recipe should not be done as written. I made this a second time in the crock pot by using two stoneware oven safe mugs, poured a can of sweetened condensed milk into each mug, covered mugs with foil to make sure water did not drip back into the mug from condensation, placed mugs into crock pot, poured in enough water to get to about 1 inch from the top of the mugs, cooked on low for 8 hours. THAT turned out well. Do not do this recipe as written.

Ingredients Nutrition


  1. Wash and remove the labels from your cans of sweetened condensed milk. Make sure the cans are undented and unopened.
  2. Stand your cans up in the slow cooker and pour water in to cover cans fully.
  3. Cook on low for at least 8 hours (I've gone up to 12 hours once when I forgot about the cans, results were still good). You could probably do this on high for 4-5 hours but I haven't tried it.
  4. Allow to cool fully before opening the can. Store in refrigerator.
  5. If you open the can and find that it's not golden enough (highly unlikely), scoop out contents into a saucepan and simmer on low until desired color.
