As requested, here is the peanut butter pie reciped. It is taken from Classic Home Desserts cookbook by Richard Sax.
Graham Cracker Crust
1 up graham cracker crumbs
1/4 cup sugar
1/4 cup unsalted butter, softened
Filling
8 ounces of cream cheese, softened
1 cup creamy peanut butter (do not use old-fashioned or freshly ground)
1 cup confectioners' sugar
2 tablespoons vanilla extract
1/2 cup heavy cream
Fudge Topping
1/2 cup heavy cream
6 ounces semisweet chocolate (chopped) - recipe called for semisweet, but I used 72%
1. For crust: Preheat oven to 350. In a medium bowl, combine the graham cracker crumbs, sugar and butter until well blended. Press evenly into a 9-inch pie pan, reaching up to but not over the rim. Bake until lightly browned, about 10 minutes Cool crush completely.
2. Filling: Beat the cream cheese and peanut butter with an electric mixer at medium speed until well blended. Add the confectioners' sugar, butter and vanilla and continue beating until fluffy.
3. Whip the cream until not quite still. Fold a large spoonful of the whipped cream into the peanut butter mixture to lighten it. Gently fold in the remainder. Carefull spoon the filling into the cooled crust, spreading evenly. Loosely cover the pie and refrigerate until firm (about 3 hours).
4. Fudge topping: Bring the cream to a simmer in a small heavy saucepan. Add the chocolate and stir until smooth. (I did this in the microwave) Set aside to cool to lukewarm. Gently spread the topping over the cooled pie. Refrigerate until firm, about 3 hours. Serve cold.
