Preheat the oven to 375°F. Line a standard cookie sheet with parchment and set aside.
Unroll the pie crust and using a 5-inch cookie cutter, cut 4 rounds. Re-roll the scraps to make a 5th round.
In a small bowl, stir together the peanut butter and marshmallow cream. Divide evenly between the dough rounds. Spread to within 1-inch of the edge.
Arrange 5 pieces of chocolate on each.
Fold the edges up at 1-inch intervals and pinch the dough together.
Toss the graham cracker crumbs, chopped peanuts and granulated sugar with the melted butter then sprinkle on top.
Bake for 18 minutes, then sprinkle the tops with mini marshmallows. Increase the oven to the broil setting and broil for 2 minutes or until the marshmallows are toasted.
