Peanut Butter Popcorn

1/2 cup peanut butter
3/4 cup brown sugar
1/2 cup (1 cube) butter
20 large marshmellows (roughly)
1 teaspoon vanilla

Over medium heat, melt butter.  Add sugar and stir until dissolved.  Add peanut butter, marshmellows, and vanilla.  Stir until melted together (if you cook it too long it will get hard instead of chewy so take it off heat as soon as it is combined).  Pour over popcorn.

*We used mini-marshmellows, probably equalling more than the 20 large mallows it calls for.  This is delightfully chewy and good the next day.  Mmmmm.  Scrumptious.
