In a medium saucepan, whisk together the heavy cream, sugar, cocoa powder, cornstarch, butter, vanilla extract, and salt.
Place the saucepan over medium-high heat and bring the mixture to a boil. Reduce the heat to low and simmer, stirring constantly, until the pudding is thickened and smooth.
Remove the saucepan from the heat and stir in the chopped dark chocolate until it is melted and incorporated into the pudding.
Pour the pudding into individual ramekins or a large bowl and chill for at least 2 hours before serving.
