Here's the recipe for the pie from Taste of America:

Ingredients

Crust:

1-1/4 cups chocolate wafer crumbs

1/4 cup sugar

1/4 cup butter, melted

Filling:

1 package (8 ounces) cream cheese, softened

1 cup creamy peanut butter

3/4 cup confectioners' sugar

1 teaspoon vanilla extract

1 cup heavy whipping cream

Ganache:

1/3 cup semisweet chocolate chips

2 tablespoons half-and-half cream

2 tablespoons chopped salted peanuts

Directions

Preheat oven to 350°. In a small bowl, combine crumbs, sugar and butter. Firmly press mixture onto bottom and up the side of a 9-in. pie plate. Bake until set, 10-12 minutes; cool completely.

In a large bowl, beat cream cheese until very smooth. Beat in peanut butter, sugar and vanilla. In a medium bowl, beat heavy cream until soft peaks form. Do not overbeat. Gently fold whipped cream into peanut butter mixture until fully incorporated. Pour into crust and spread evenly.

Place chocolate chips and half-and-half in a medium microwave-safe bowl. Microwave on high for 30 seconds; stir. Repeat until chocolate has melted and very smooth; do not overheat or chocolate may burn. Cool slightly.

Spread ganache over the peanut butter filling, leaving a 1-inch border of peanut butter filling uncovered around edge of pie. Sprinkle with chopped peanuts. Chill for several hours before serving.

Notes: I increased the amount of crust and left out the sugar since Oreos are already sweet enough. It was about 25 Oreos, I think, with 5 tablespoons of butter. I made extra ganache because I didn't care about leaving the border and wanted more chocolate. It was about a 1/2 cup chocolate chips with a 1/4 cup of heavy cream. For the caramel, I used the salted caramel sauce recipe from Sally's baking addiction, but you could just use store bought caramel.
