Instructions
In a heatproof bowl, melt the dark chocolate and butter together using a double boiler or in short bursts in the microwave. Stir until smooth, then set aside to cool slightly.
In a separate bowl, whip the egg whites until soft peaks form. Gradually add in half of the granulated sugar and continue whipping until stiff peaks form.
In another bowl, whip the heavy cream until soft peaks form. Add the remaining sugar and peppermint extract, and continue whipping until stiff peaks form.
Gently fold the melted chocolate mixture into the whipped cream until well combined.
Carefully fold in the whipped egg whites to the chocolate and cream mixture until the mousse is smooth and well incorporated.
Spoon the mousse into individual serving glasses or bowls.
Refrigerate for at least 2-3 hours, or until the mousse is set.
Before serving, garnish with crushed candy canes or peppermint candies if desired.
