Heat chocolate chips and heavy cream together over low heat or use a double boiler to prevent seizing, ensuring a silky, smooth filling without graininess.

Use a kitchen torch to toast the marshmallows directly on the pie just before serving for authentic campfire char and caramelized exteriors, rather than baking them.

Refrigerate the assembled pie for at least 2-3 hours (or overnight) to set the chocolate layer completely, making it easier to slice cleanly and preventing marshmallows from sinking.

Toast the graham cracker crust with melted butter and a pinch of salt before filling to deepen its flavor and create a sturdier base that won't become soggy.

Use a 1:1 ratio of chocolate chips to heavy cream by weight for the perfect ganache consistency—too thin and it won't set properly, too thick and it becomes difficult to spread.
