Step 1

Blind Bake Pie crust and allow to cool completely.

Step 2

To a medium sauce pan over medium heat, add the sugar, and milk and whisk well to combine. Bring mixture to a simmer, whisking frequently.

Step 3

Meanwhile, add the egg yolks and cornstarch to a bowl and whisk until smooth.

Step 4

Once the saucepan mixture is simmering, add a few spoonfuls of the hot liquid into the egg yolks and whisk to temper the eggs. Add a few more spoonfuls of the hot liquid into the egg yolks. Then slowly whisk the egg yolk mixture back into the saucepan. Whisk constantly until the mixture begins to thicken and comes to a very gently boil (big bubbles begin to break the surface).

Step 5

Remove pan from the heat and whisk in the butter, chopped chocolate, and vanilla extract. Stir until completely smooth.

Step 6

Pour filling into the cooled crust and smooth into an even layer. Place a piece of plastic wrap gently on top and refrigerate until filling is set, about 4–6 hours or overnight, if desired.

Step 7

In a medium saucepan add brown sugar, granulated sugar, butter, egg yolks, and evaporated milk. Stir to combine and bring the mixture to a low boil over medium heat. Stir constantly for several minutes until the mixture begins to thicken.

Step 8

Remove from heat and stir in vanilla, nuts and coconut. Allow to cool completely before layering it on the pie.
