In a medium bowl, combine graham cracker crumbs, pecans, sugar, salt, and butter. Press mixture into the bottom and up the sides of a 9-inch deep-dish pie plate or tart pan with a removable bottom.
Bake for 8 minutes. Remove from oven, and let cool completely.
In a large bowl, combine pudding mix, buttermilk, and vanilla, whisking until thickened, approximately 2 minutes. Whisk in whipped topping and ground chocolate. Pour mixture into cooled crust. Cover tightly.
Freeze for at least 8 hours or up to overnight. Remove from freezer and refrigerate until serving. Store, covered tightly, in refrigerator, for up to 1 week.
Notes
*We used Ghirardelli.
Kitchen Tip: Serving your icebox delights on a sweltering summer day? Place your pies in the freezer for 1 to 2 hours before serving to keep them from melting too quickly.
