Divide pudding between 4 ramekins. Let the pudding cool for about 10-15 minutes.
Press a piece of plastic wrap to the surface of the pudding, and chill for about 1-2 hours before serving.
Top with dollops of sweetened whipped cream and chocolate shavings, if using.
Notes
Sugar: The pudding isn't super sweet. If you'd like sweeter pudding, increase the sugar to 1/2 cup.
Bittersweet baking chocolate: I use the Ghirardelli 60% bittersweet chocolate baking bars for this recipe. However, if you would like sweeter pudding, you could use semisweet baking chocolate instead.
Milk: For pudding that isn't as rich, use 1% or 2% milk.
Egg yolks: Since this pudding only uses yolks, it's a great way to use up any leftover egg yolks you might have.
