Using an electric mixer, fitted with the whip attachment, beat the cream cheese and sugar until smooth. Add the peanut butter, milk and roasted peanuts and beat well. Fold 2 cups of the whipped cream into the cheese mixture. Pour the filling into the prepared crust. Place the pie in the refrigerator and chill completely, about 2 hours. Slice the pie into 8 servings. To assemble, place one piece of pie on each plate. Dollop each piece of pie with the remaining whipped cream. Garnish each piece with the salted peanuts, drizzle of chocolate sauce, chocolate curls and mint.
