Melt butter, sugar and a pinch of salt in a saucepan.
Add chopped dark chocolate.
Sift in the cornstarch until you get a smooth pasty consistency.
Gradually pour in the milk while continuously whisking to create a smooth mixture.
Cook until it thickens for about 5 minutes.
Pour the pudding into slightly oiled individual serving dishes or a large bowl. Let it cool at room temperature for a bit before refrigerating.
Cover the pudding with plastic wrap, making sure it touches the surface to prevent a skin from forming on the surface. Refrigerate for at least 2-3 hours, depending on the size of the serving dish you are using, or until it's completely chilled and set.
Once the pudding is chilled, you can serve it as is or with a topping of your choice. Cocoa powder, whipped cream, chocolate shavings, or fresh berries are great options but feel free to get creative.
