2 tablespoons melted butter
1 cup whipping cream
1 tablespoon vanilla

TOPPING:
4 ounces semisweet chocolate
2 tablespoons butter
2 tablespoons oil

Whip cream until firm. Whip in vanilla and set aside. Whip cream cheese until fluffy, then slowly add sugar, peanut butter and butter. Blend 1/3 of the whipped cream into peanut butter mixture. Fold peanut butter mixture into remaining whipped cream. Fill pie crust, smoothing top. Carefully wrap with plastic and chill overnight.
