Caramel popcorn

We tried this from pinterest click here if you want the original recipe.  It was really good and the caramel stayed gooey which is a must for me. This stuff is the BOMB!! Soft Caramel for Popcorn:
1c brown sugar,
1 stick butter,
1c karo syrup,
1 can sweetened condensed milk.
heat everything up until sugar is dissolved and it starts to bubble. This makes a lot of caramel so either half it or make a big big batch of popcorn.
