Spoon ½ of the melted chocolate into the prepared tart pan. Using a large spoon or offset spatula, evenly spread the chocolate over the bottom of the tart pan and up the sides of the pan. Chill the coated tart pan in the refrigerator while preparing the chunky peanut butter filling.

Remove the chocolate-coated tart pan from the refrigerator. Using either a silicone spatula or an offset spatula, spread the chunky peanut butter mixture into the bottom of the coated tart pan. Be sure the chunky peanut butter mixture is smooth and even.
Spoon the remaining melted chocolate mixture on top of the chunky peanut butter layer. Use the spoon or an offset spatula to evenly smooth the chocolate all the way to the sides.
Once the remaining chocolate has been spread, gently tap the tart pan to ensure the chocolate settles. Chill in the refrigerator for 4 hours to overnight.
When you are ready to serve, remove the tart pan from the refrigerator. To remove the peanut butter cup from the tart pan, center the pan over a small mixing and apply slight pressure to the edge of the tart pan to encourage the sides to come away. Have a serving platter or 10-inch cake circle ready to place the peanut butter cup pie on.
Gently flip the pie upside down to remove the removable tart pan bottom, and carefully peel off the parchment circle. Place the serving plate or cake circle over the bottom of the pie and flip the pie back over.

To Store: Store any leftovers in an airtight container for up to 7 days.
To Freeze: To freeze, wrap the pie in a layer of plastic wrap, then overwrap it in tin foil, and freeze it for up to 3 months. When you are ready to serve it, thaw it overnight in the refrigerator.

If you do not have a parchment circle, you can generously spray the removable circle with nonstick spray, or you can lightly butter the removable circle.
Before slicing, allow the pie to sit at room temperature for 20 minutes before slicing.
I find it easiest to cut the pie with a warm, dry knife so it'll slice through the thick chocolate.
