The original version of this recipe called for unwrapping store bought candies and melting them to make the caramel layer. I updated the method with a homemade, darker caramel (actually faster to make than unwrapping 50 sticky candies!) and a slightly more sophisticated flavor profile from the addition of walnuts and bittersweet chocolate. Our family is divided on the subject of walnuts, so I usually make half with and half without.
