Make the crust: In a large bowl, whisk together the flour and salt. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Gradually add the ice water, mixing until the dough just comes together. Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes.
Preheat oven to 350°F (175°C). Roll out the dough on a lightly floured surface and transfer it to a 9-inch pie plate. Crimp the edges.
Make the filling: In a large bowl, combine the pecan halves, corn syrup, granulated sugar, brown sugar, melted butter, bourbon, cocoa powder, vanilla extract, and salt. Whisk in the beaten eggs until well combined.
Pour the filling into the prepared pie crust.
Bake for 50-60 minutes, or until the filling is set and the crust is golden brown. Let cool completely before slicing and serving.
Notes
Serve with whipped cream or a scoop of vanilla ice cream for an extra special treat.
