Preheat oven to 325 degrees. Lightly grease a 9-inch pie pan.
Form the pie crust around the pie plate, crimping and bedazzling the rim as you wish. Set in the fridge for 15 minutes to chill.
In a large bowl, beat the eggs until frothy and bubbly, about 2-3 minutes. Add the brown sugar, sugar, vanilla, flour, baking soda, and salt. Whip until combined, then add the butter and beat to incorporate. Fold in the chocolate chips and walnuts with a spatula.
Spread the filling evenly into the pie crust. Sprinkle a few more chocolate chips atop. Bake 55-65 minutes until an inserted toothpick emerges with just a few moist crumbs, and the top is set and crinkly.
Cool the pie at least 30 minutes, then slice and enjoy!
