Gooey Caramel Popcorn

If you like the sticky, gooey kind of caramel popcorn then this recipe is for you!
Ingredients:
2 cups brown sugar
1 cup white Karo syrup
1 cube butter
1 can sweetened condensed milk
1 LARGE bowl of popcorn. I mean really large. The sauce makes a lot. I think I made around 5-6 batches of popcorn (air popped)

In a large saucepan bring sugar, Karo syrup and butter to a boil. Add milk and cook for 5 minutes over medium heat, but DON'T bring back to a boil. Pour over popcorn, stir to coat evenly. Let cool. Enjoy!
