  • Slowly pour the hot cream into the egg yolk mixture while whisking to temper.
  • Return the custard to the saucepan. Whisk over low heat until it thickens and coats the back of a spoon. Remove from the heat and cool completely.
  • In the bowl of a stand mixer or hand mixer, beat the egg whites, remaining sugar, and cream of tartar for 2-3 minutes until there are stiff peaks.

  • Gently fold the meringue into the cooled custard in 2 additions until no white streaks remain. Don't overmix.
  • Portion the mousse into 4-5 cups. Cover with plastic wrap and chill for 1-2 hours.
  • Remove the plastic wrap. Dust with cocoa powder, garnish with coffee beans, and enjoy!

Notes

Carefully separate the egg whites and yolks before starting. Don't get any yolks in the whites or they won't whip up properly.
Storage: Store coffee mousse in an airtight container in the refrigerator. It stays fresh for 2-3 days.
