Preheat the oven to 325°F. Press pie crust into a 9-inch pie dish and crimp as desired. Set aside.
In the bowl of an electric mixer beat the eggs on high until light and foamy, 2-3 minutes. Add the flour, sugar, brown sugar and vanilla and mix on low until combined. Add cubed butter and beat until incorporated. Stir in the chocolate chips and walnuts by hand.
Spoon the dough into the pie shell and spread into an even layer. Add more chocolate chips on top if desired.
Bake for approximately 1 hour until a knife inserted halfway from the edge and the center comes out clean. The top should be golden brown.
Cool on a wire rack slightly for 20-30 minutes so the center has a chance to finish setting up. But don't let it cool completely! Serve warm with whipped cream or ice cream, or as desired.
- If using unsalted butter, add 1/4 teaspoon salt. Butter should be nice and soft at room temperature, but not melted. Cubing it before adding it to the batter helps it incorporate more easily.
