Line a 9 x 13 inch pan with foil. Sprinkle with ground nuts. Arrange Hershey bars on top of nuts, writing side up (it takes about 8 candy bars). Have the same amount of ground nuts, and the same number of unwrapped candy bars standing by.
In a skillet, cook 2 sticks of butter and 1 cup of sugar for about 15 minutes, stirring constantly, until the mixture is dark (or at the hard boil stage). Pour on top of candy bars. Top with remaining candy bars, writing side down, and then the nuts. Let cool completely and cut or break into pieces. Yum.
