In a large saucepan melt the butter. Add a pinch of salt and stir.
Pour a bag of mini marshmallows, reserving one cup for later, into the melted butter. Stir until completely melted.
Once melted, turn off the stovetop. Add in the Golden Grahams cereal and fold into the marshmallow mix until evenly coated.
Line an 11x7 baking dish with parchment paper. Pour the cereal mix into the dish, evenly spreading.
Place a Hershey chocolate on the cereal. I placed one Hershey bar for each ‘slice’ I would cut later. I wanted to make sure everyone got a piece! Press the bar gently into the cereal mix.
Pour the remaining cup of mini marshmallows on top, pressing them gently.
