In a medium saucepan, combine heavy cream, milk, and sugar.
Heat the mixture over medium heat, stirring until sugar dissolves.
Add cocoa powder and salt, whisking until fully combined.
Continue cooking for about 5 minutes, ensuring the mixture doesn’t boil.
Remove from heat and stir in vanilla extract.
Allow the mixture to cool slightly before pouring it into serving glasses.
Refrigerate for at least 2 hours to set.
Once set, whip additional cream to top each dessert.
Garnish with chocolate shavings.
Serve chilled and enjoy!
