Preheat oven to 350°F.
Prepare and roll out pie crust. (You'll only need half of my favorite homemade recipe.) Place in a buttered 9-inch pie dish, and flute edges. Set aside.
In a large mixing bowl, whisk together melted butter and sugars
Add eggs, vanilla, bourbon, and flour, and whisk again until combined.
Fold in chocolate chips and walnuts.
Pour filling into prepared pie crust.
Bake at 350°F for about 45 minutes, until edges are set.
