Start by placing the chopped milk chocolate and unsalted butter in a heatproof bowl. Set the bowl over a saucepan of simmering water, creating a double boiler. Stir occasionally until the chocolate and butter are fully melted and smooth. Remove from heat and stir in the freshly brewed Harry and David Tiramisu Coffee. Set aside to cool slightly.
In a large mixing bowl, pour the cold heavy cream. Using a hand mixer or stand mixer, whip the cream on medium speed until soft peaks form. Be careful not to overwhip, as you want a light and airy texture.
In another bowl, whisk together the egg yolks and sugar until the mixture is pale and creamy. This should take about 2-3 minutes of whisking.
Once the melted chocolate mixture has cooled slightly, slowly add it to the egg yolk mixture, whisking continuously to combine. This will create a rich chocolate base.
Gently fold one-third of the whipped cream into the chocolate mixture to lighten it. Then, add the remaining whipped cream and fold until just combined. The aim is to keep as much air in the mixture as possible for a fluffy mousse.
Spoon the mousse into serving glasses or bowls and refrigerate for at least 2 hours, or until set.
Before serving, top each mousse with a dollop of extra whipped cream, a light dusting of unsweetened cocoa powder, and a few coffee beans for garnish. Enjoy your Whipped Tiramisu Coffee Chocolate Mousse!
