Put unopened can of sweet condensed milk in the crockpot, without the label.
Fill your crock pot with enough water so the can is completely covered.
Put the lid on crock pot.
Cook on low for 7 or so hours. Mine cooked for 10 and it's perfectly fine.
Viola! Caramel. (aka dulce de leche) And it's delicious.
*Although I have seen this recipe several times on Pinterest, it was Kate who finally got me to try it. Rather, she did it so I wanted to do it too. However, fear not. I would not jump off a bridge just because she did. I wouldn't even walk on that bridge to the center to watch her jump. Me scared.
