Quick and easy and delicious.
Over medium heat in a large pan, heat milk, butter, and sugar.
Stir in marshmallows and bring to a boil, stirring constantly.
Remove pan from heat, add unsweetened chocolate, Hershey bar, and chocolate chips.
Additional nuts may be added. Stir until mixture is the same color throughout.
Place in well buttered jelly roll pans, depending on how thick you want, as this makes a large amount.
Refrigerate until set, then cut and enjoy!
