Remove the pie crust from the oven, and reduce the oven temperature to 325°F.
Microwave the chocolate chips and milk beverage in a microwave-safe bowl on HIGH for 60 seconds, and whisk until smooth. If not fully melted, heat in 15 second intervals and whisk. Do not overheat the chocolate!
Pour the melted chocolate evenly over the pie crust.
Put the eggs in a large mixing bowl and beat with a hand mixer to combine. Add the corn syrup, sugar, buttery spread or oil, vanilla, cinnamon, allspice, and salt and beat with a hand mixer on low until smooth. Foid in the pecan halves.
Slowly pour the pecan mixture over the chocolate layer.
Place a ring of foil over the crust edge to prevent over-browning.
Bake for 55 to 60 minutes or until the filling is puffed and center is still soft enough to move when shaken gently.
Let the pie cool completely on a wire rack before slicing.
