Form the pie crust into a 9” pie pan, or a 10” cast-iron skillet and set in the refrigerator until ready to use.
In a large bowl whisk together the sugars, cocoa powder, cornstarch, and salt until combined.
Next, mix in the milk and then the eggs 1 at a time until mixed in.
Finish by whisking in the melted butter and vanilla until completely combined and smooth.
Transfer the batter to the pie shell and pour it in. Bake at 350° for 45-50 minutes or until the pie has become firm with a slight jiggle in the center.
Remove the pie and cool to room temperature.
Serve as is with optional whipped cream or chill it and serve it cold.
Notes
Make-Ahead: You can serve this pie just an hour after removing it from the oven, or you can make it up to 2 days ahead of time.How to Store: Cover and keep in the refrigerator for up to 5 days. This will freeze well and be covered for up to 2 months. Thaw in the refrigerator for 1 day before serving.If you like a thicker pie, you can double the filling recipe, set it in a deep-fluted pie pan, and bake for an additional 45-60 minutes.You do not have to use a cast-iron skillet like I did. You can use a standard 9” pie pan.The most popular ways to serve it are at room temperature, chilled in the refrigerator until cold, with whipped cream, powdered sugar sprinkled on top, or alongside fresh berries.
