Pour Sweetened Condensed Milk equally into 4 jars, leaving 1″ of space at the top of each jar.
Screw lids on VERY tight.
Place jars in Crockpot, then fill Crockpot with warm water until jars are fully submerged, with about an extra 1″ of water above the jar lids.
Cook on LOW for 9 hours.
After 9 hours, carefully remove jars with tongs {they’ll be HOT}, and allow to cool for 30 minutes.
After jars have cooled, remove lids, grab some apple slices, and start dipping into your delicious caramel sauce!
Notes
Extra Caramel Sauce can be stored in the refrigerator for up to 2 weeks. Enjoy cold throughout the week, or microwave to soften it up before using. ENJOY!
