Separate out 2 tablespoon of heavy cream and place the remaining ½ cup in the refrigerator to chill.
Place chopped chocolate into a mixing bowl. Heat 2 tablespoon heavy cream in microwave for about 30 seconds or until hot, but not boiling. Pour over chocolate and whisk to melt.
Stir in Swerve, vanilla, and a pinch of salt and whisk until smooth. If necessary, heat in microwave in additional 10-second intervals until sweetener is fully melted and chocolate mixture is smooth. Chill in fridge 15 minutes.
Beat chocolate mixture 2 minutes until smooth and lightened in color, then beat in softened cream cheese for at least another 2 minutes. Mixture should be creamy and fluffy.
In a chilled, medium bowl, using a chilled whisk mixer attachment, beat remaining chilled heavy cream until stiff peaks form. Fold or whisk whipped cream into whipped chocolate mixture until well combined.
Optional Keto Whipped Cream Topping: Combine chilled heavy cream, vanilla, and Confectioner's Swerve in a chilled bowl and beat on high speed with a chilled whisk attachment until soft peaks form.
Pipe or spoon mousse into small serving bowls or ramekins and serve immediately or chill until ready to serve.
When ready to serve, top with whipped cream, chocolate shavings, and raspberries, if desired.
