For the Love of the Stove

This is a recipe courtesy of my Mom.  I think she got it before I was born, off of the Kellogg's Rice Krispy cereal box.  This is one that my friends from high school, college and after, still request.  It is the one that everyone wants me to bring or asks for the recipe, and couldn't be easier.  This is my kind of rice krispy treat, no marshmallow for me.

1 c light karo syrup
1 c peanut butter
