In a large mixing bowl, beat 16 oz softened cream cheese with ¾ cup confectioners sugar until smooth and creamy.
Add 1 cup creamy peanut butter to the cream cheese mixture and mix until fully combined.
Fold 16 oz thawed whipped topping gently into the peanut butter mixture until evenly combined and fluffy. Stir 1 cup mini Reese’s peanut butter cups into the filling mixture
Spoon the filling evenly into the graham cracker pie crust and smooth the top with a spatula. Drizzle ¼ cup Hershey’s syrup evenly over the top of the pie.
