Start by placing your 9-inch chocolate pie crust in a suitable pie dish. If you’re using a store-bought crust, ensure it’s thawed if frozen.
In a mixing bowl, add the softened cream cheese. Using a hand mixer or stand mixer, beat the cream cheese until it’s smooth and creamy. This step is crucial for ensuring there are no lumps in your filling.
To the smooth cream cheese, add 1 cup of powdered sugar and 7 ounces of marshmallow fluff. Mix again until everything is well combined and creamy.
Now, take 12 ounces of the Cool Whip and gently fold it into the cream cheese mixture using a rubber spatula. Be careful not to deflate the mixture; you want it to remain light and fluffy.
Break the 6 Hershey's chocolate bars into pieces and gently incorporate them into the filling. This will give your Hershey Pie those delicious chocolatey bites.
Pour the creamy filling into the prepared chocolate pie crust, spreading it evenly with your spatula.
Cover the pie with plastic wrap and refrigerate for at least 4 hours, or overnight for best results. This allows the filling to set and the flavors to meld beautifully.
Before serving, take the remaining 4 ounces of Cool Whip and spread it on top of the pie. For a decorative touch, shave additional Hershey's chocolate bars over the top and drizzle with hot fudge sauce. Slice and serve chilled. Enjoy your homemade Hershey Pie!
