- 1 cup milk
- 2 tablespoons milk
- 48 large marshmallows, chopped
- 8 (1.55 ounce) bars chocolate candy (such as Hershey's®)
- 3 cups heavy whipping cream
- 30 graham cracker squares, crushed
- 1/4 cup white sugar
- 6 tablespoons butter, melted
- Pour both amounts of milk into a saucepan, place over medium heat, and bring milk almost to a simmer, stirring often. Add marshmallows and chocolate candy bars. Stir until marshmallows and chocolate melt and the mixture is smooth. Set aside to cool.
- Whip cream in a large bowl until fluffy and cream holds stiff peaks when beaters are lifted straight up, about 5 minutes. Gently fold cooled marshmallow mixture into whipped cream.
- Combine graham cracker crumbs, sugar, and butter until crust mixture is evenly moist. Press mixture into the bottom of a 9×13-inch dish. Spread marshmallow filling evenly over the crumb crust. Refrigerate until set, about 2 hours.
