Step 1

Combine the sugar, cornstarch, and salt in a medium saucepan. Stir or whisk together.

Step 2

Pour in milk and egg yolks, and whisk together.

Step 3

Stir over medium heat until the mixture just barely comes to a boil and becomes thick, about 6-8 minutes (maybe less, maybe more; just watch it!) The second it starts to bubble and thicken (note: It should be thick like pudding!) remove it from the heat. Add the chocolate, vanilla, and butter, and stir until everything is beautifully combined.

Step 4

Pour the pudding into the pie crust (if there is extra, spoon it into small dishes) and place in the fridge to chill for 4 hours uncovered.

Step 5

Cut into slices and serve with whipped cream!
