In a large bowl, whisk the sugar, cocoa powder, evaporated milk, butter, eggs, and vanilla until smooth. Pour into the prepared pie crust.
Bake for 45 minutes or until the edges are set and the center of the pie is still slightly jiggly. Place the pie plate on a rack to cool slightly before serving.
May be served hot, cold, or at room temperature. Enjoy!
Notes
Adapted from Handle the Heat.Pie stores very well at room temperature for about 2 days, after that stick it in the fridge. It's delicious cold!When you're shopping, take note to buy evaporated milk instead of sweetened condensed milk. They are not the same!
