Preheat the oven to 350 degrees F. In a bowl combine the crumbs, butter and 1/4 cup of the peanut butter. Mix thoroughly. Press the mixture into a 9-inch spring-form pan. Bake until golden and crisp, about 6 to 8 minutes. Remove from the oven and cool completely. Using an electric mixer, beat the cream cheese with sugar until smooth. Add the remaining 3/4 cup peanut butter. Beat until smooth. Add the milk and roasted peanuts and beat well. Fold 4 cups of the whipped cream into the peanut butter mixture and spoon into the prepared pan. Cover with plastic wrap and refrigerate until firm, about 2 hours. Remove from the refrigerator and spoon the remaining whipped cream over the entire pie. Slice into individual servings. Garnish with the peanuts, chocolate shaving and chocolate sauce.
