Remove the pie plate from the freezer once the chocolate layer has set.
Spread the peanut butter filling mixture evenly over the chocolate layer.
Put the remaining whipped cream in a piping bag fitted with a star tip and pipe small circles around the edge of the pie.
Place the remaining chopped Reese's in the center of the pie, inside of the piped whipped cream circles.
Drizzle the top of the pie with caramel and chocolate sauce.
Allow to set in the fridge for at least an hour before enjoying. Serve chilled. Store in the fridge for up to 1 week, or freeze for 6-8 weeks.
