Ingredients

Instructions

  1. Step 1: Place 6 oz chopped dark chocolate in a heatproof bowl. Pour 1/4 cup hot freshly brewed espresso over the chocolate and let sit for 2 minutes, then stir gently until smooth and glossy.
  2. Step 2: In a separate bowl, whisk 3 egg yolks with 2 tbsp granulated sugar and 1 tsp vanilla extract until pale and thick, about 3 minutes.
  3. Step 3: Fold the chocolate-espresso mixture into the egg yolk mixture until fully combined.
  4. Step 4: In another clean bowl, beat 3 egg whites with a pinch of salt until soft peaks form. Gradually add 1/4 tsp ground cinnamon and continue beating until stiff peaks form.
  5. Step 5: Gently fold one-third of the egg whites into the chocolate mixture to lighten it, then fold in the remaining whites carefully to keep the mousse airy.
  6. Step 6: Whip 1/2 cup heavy cream until soft peaks form and fold into the mousse gently.
  7. Step 7: Spoon the mousse into serving glasses and refrigerate for at least 3 hours before serving to set.
