Step 1: Prepare the Pie Crust

1. In a medium bowl, mix together the graham cracker crumbs, melted butter, and granulated sugar until well combined.
2. Press the mixture firmly into the bottom and up the sides of a 9-inch pie pan to form the crust.
3. Place the crust in the refrigerator while you prepare the filling.

Step 2: Make the Chocolate Layer

1. In a small saucepan, heat the heavy cream over medium heat until it begins to simmer.
2. Remove from heat and pour the hot cream over the chocolate chips in a bowl. Let it sit for a minute, then stir until smooth and glossy.
3. Pour the melted chocolate into the chilled pie crust, spreading it evenly. Return the pie to the refrigerator to set while you make the caramel cream filling.

Step 3: Prepare the Caramel Cream Filling

1. In a large mixing bowl, beat the softened cream cheese until smooth and creamy.
2. Gradually add the powdered sugar and vanilla extract, mixing until well combined.
3. In a separate bowl, whip the heavy cream until stiff peaks form.
4. Gently fold the whipped cream into the cream cheese mixture until fully incorporated. Then, fold in the caramel sauce until combined.

Step 4: Assemble the Pie

1. Pour the caramel cream filling over the chocolate layer in the pie crust, spreading it evenly.
2. Cover the pie with plastic wrap and refrigerate for at least 4 hours, or until set.

Step 5: Serve

1. Before serving, top the pie with whipped cream, chocolate shavings or cocoa powder, and drizzle with additional caramel sauce.
2. Slice the pie into wedges and serve chilled.
