Gooey Popcorn Balls

* 3 bags popped microwave popcorn
*1 bag mini marshmallows
*1 cube butter
* 1 c. brown sugar
* 2 tsp. vanilla

After popping popcorn, remove unpopped kernels. Put popcorn into 1-2 large mixing bowls. In a large saucepan, melt marshmallows, butter & brown sugar. Stir continuously, until sugar is dissolved. Remove from heat & add vanilla. Pour mixture over popcorn & stir. Once slightly cooled, use hands and form popcorn into balls. (Sometimes spraying hands with non-stick spray or rubbing a little butter on them will help the mixture not to stick to you!) Place on waxed paper & allow to set (or just eat!).
