To make the nutty wafer crust, preheat the oven to 350 degrees. Lightly oil a 9-inch deep dish pie plate. In a medium bowl, stir together the cookie crumbs, peanuts and butter until well combined. Press the mixture evenly into the bottom and up the sides of the prepared pie plate. Bake the crust for 8 to 10 minutes, or until set. Cool on a wire rack.
To make the chocolate-peanut butter filling, in a medium saucepan, stir together the sugar and the cornstarch until well combined. Gradually whisk in the milk and egg yolks until smooth. Place over medium heat and bring to a gentle boil, whisking constantly. Continue to whisk for another minute, or until the mixture is thick. Remove from the heat and whisk in the peanut butter.
In a small bowl, combine 1 cup of the hot peanut butter mixture with the chopped chocolate and stir until the chocolate in melted, scrape the mixture into the baked crust. Cover with plastic wrap, pressing it directly onto the surface, and chill for 1 hour, or until set. Transfer the remaining peanut butter mixture to a medium bowl, cover with plastic wrap, and chill for 45 minutes, or until cool but not set.
In a medium bowl, using a handheld electric mixer, beat the cream until soft peaks form. Using a rubber spatula, gently fold the cream into the cooled peanut butter mixture. Remove the plastic wrap from the pie. Scrape the mixture onto the chocolate filling and, using a small offset metal spatula, smooth into an even layer. Chill for 1 hour, or until set.
To make the whipped cream topping, in an electric mixer, using the whisk attachment or beaters, beat the cream on medium-low speed for 30 seconds. Increase the speed to medium-high and add the sugar. Beat until the cream forms soft peaks. Using a rubber spatula, pile the whipped cream evenly over the pie filling. Use the spatula to swirl the cream attractively over the pie. Sprinkle the peanuts over the cream. Chill the pie before serving.
