Caramel Corn

I thought of posting this, mainly because I need more time for my 10 hour project, and because I'm eating it while I type.

1 Stick Butter
1/2 cup Corn Syrup
1 cup Brown Sugar

In the microwave, bring to a boil (approx. 2 minutes). Then add 1/2 can sweetened condensed milk, and cook 4 more minutes (or until it forms a ball in ice cold water), stirring every 2 minutes. Take out of microwave and add 1 tsp vanilla. Pour over popcorn.
