Peanut Butter Popcorn Balls

I've been wanting to make homemade popcorn balls for a while now, but I debated over what binder to use, marshmallows or syrup. The marshmallow kind are more chewy, like rice crispy treats, while the kind made with syrup are more crunchy. Since the syrup kind is more traditional and what I remember eating as a kid, I ended up going that way. The addition of peanut butter to the syrup in this recipe produces a chewier texture and prevents the finished popcorn balls from getting rock hard, which the kind made with syrup have a tendency to do. With peanuts, peanut butter, and Reece's Pieces, these are definitely for peanut lovers.
