Toffee Bars are a rich and chewy dessert layered with chocolate and optionally topped with chopped nuts. This vintage recipe reflects classic mid-century American baking—simple ingredients, handwritten directions, and the unmistakable flavor of melted Hershey bars. Beloved for its buttery base and gooey chocolate top, these bars strike the perfect balance between cookie and candy, ideal for gatherings, potlucks, or cozy nights in.
