In this easy recipe from 1965, the peanut butter is mixed up with some crispy rice cereal (sort of making a batch of PB Rice Krispies squares), then the topping layer is made simply by melting chocolate chips and butterscotch chips together.
Let them cool, then cut ’em up into bars, and you have a treat everyone will want to try!
