Ok I totally get why people do the condensed milk caramel in the slow cooker now, it is so lush! Look at that shine. I’ll never do it on the stove top again. I cooked it in my 3L with 2 tins was on low for 7 hours I think and left overnight to cool. And yes I totally licked the spoon at 8am lol, so hard to resist. I’m going to use it in caramel tarts for Christmas day 
Edited:Ingredients
A can of sweetened condensed milk
Ring pull cans are ok … Just place ring pull cans ringpull end down in the slow cooker
Directions
Place unopened can of sweetened condensed milk into your slow cooker.
Cover the can completely with water… It doesn’t really matter the temperature of the water… I try to make sure there is at least 2 inches of water over the top of thecan (VERY IMPORTANT)
Put the lid on. Your slow cooker… No tea towel.
Put your slow cooker on high for up to 4 or 5 hours or 7-8 hours on low… Depending on how thick you want your caramel, to the amount of time it’s in there. Mine was 4.5 hours on high.
I checked mine every hour or so to make sure the water level hadn’t dropped… It didn’t…
After the time is up, patience is required…. Allow can of caramel to cool completely before opening… The caramel is under pressure in the tin and you don’t want molten caramel to explode out at you from a hot tin (VERY IMPORTANT)….. I just left mine in the slow cooker over night.
Then open and use for your delicious treats…. We have been known in my house to eat the caramel straight out of the can with a spoon…. Yes it’s that good!! ?
