Preheat the oven to 375°F. Lightly spray a 9-inch or 10-inch pie plate with cooking spray. [Pictured: 10-inch deep dish pie plate]
Fit the pie crust into the pie dish, crimping the edges.
Pour the pecan halves and 1 cup of mini semisweet chocolate chips evenly over the bottom of the pie shell.
In a large microwave safe bowl, melt the remaining 1/2 cup of mini chocolate chips with 2 Tbsp of butter. Melt in 20 second increments stopping to stir each time. Repeat until smooth. Whisk in the dark corn syrup, and both sugars. Add the vanilla and salt.
Add 4 large eggs, whisking until fully combined.
Pour the filling evenly over the pecans and mini chocolate chips in the pie crust. Use the tip of a knife to gently move around the chocolate chips and pecans to allow the filling to go seep throughout. (Alternately, you can mix everything together in a mixing bowl and pour into the unbaked pie shell.)
Place into the oven and bake at 375°F for 20 minutes. Lower the oven temperature to 325°F for another 20-25 minutes, or until the center is set when the pan is gently shaken.
Cover the edges of the crust with aluminum foil halfway through cooking to prevent over browning, if needed.
Cool chocolate pecan pie on a wire rack until warm to the touch before slicing.
Serve with a scoop of vanilla ice cream or a dollop of fresh whipped cream
