Blending this decadent drink with freshly whipped cream gives it a deliciously fluffy texture. Serve with more whipped cream on top.
In a saucepan, combine milk, chocolate, sugar, cocoa powder, and salt. Heat over medium, whisking frequently, until chocolate melts and mixture is smooth. Let cool. Transfer 1 cup to an ice-cube tray and freeze; refrigerate the rest.
Whip cream to soft peaks. Blend two-thirds of the cream with both chilled and frozen hot chocolate. Divide into two glasses and top with remaining whipped cream.
