Caramel Popcorn

This is one of my husband's favorite treats!  In fact he's the one that makes it!  I love this caramel popcorn because it is soft and gooey!  Although if you let it sit it hardens up a little.  I got the recipe from my neighbor Allison.  She likes to use 3 bags of microwave popcorn, instead of the kind you pop yourself.  Both work great.

2 1/2 cups brown sugar
1 cup corn syrup
1 (14 oz) can sweetened condensed milk
1 cube butter
popcorn

Pop 1 cup dry popcorn and place in a large bowl or pan.  In a saucepan, bring sugar and corn syrup to a boil.  Add sweetened condensed milk and butter.  Boil for 1 minute.  Pour over popcorn.  Stir and serve.
