Preheat the oven to 325°F (162°C). Then, grind the graham crackers in a food processor until fine, and add the melted butter; stir to combine.
Press the mixture into a prepared pie plate using the back of a measuring cup or spoon and bake for 10 minutes.
Allow the crust to cool, and line Hersey's bars onto the pie crust in 1-2 layers, depending on how chocolatey you want it to be.
Layer the marshmallows over the chocolate. Arrange the oven rack to the lower or middle position. Place the pie in the oven and bake for 10-15 minutes until the marshmallows are puffed and golden brown.
Drizzle with melted chocolate and top with graham crackers to serve.
