Caramel Popcorn

STICKY SWEET CARAMEL CORN - graciously shared by Christine Lewis
¾ pound butter (yes really)
1 bag mini marshmallows
1 cup brown sugar
2 tsp. vanilla
1 bag of pre-prepared popcorn (2 lb.)
2 grocery paper bags

In a saucepan melt the butter. Add the brown sugar and stir until dissolved and bubbling. Remove from heat and add the marshmallows and stir until melted. Next add the vanilla and mix well. Now split the popcorn into the two grocery bags and then pour half the marshmallow mixture in each of the bags. Shake and manipulate the bags until well mixed. Form into ball or serve in a bowl.
