In a double boiler, melt the chocolate in 1 cup of the cream over medium heat

Allow to cool slightly

In a stand mixer, beat the remaining whipping cream with the powdered sugar and salt until stiff peaks form

Gently fold the two mixtures together, and spoon into a pastry bag fitted with a star tip

Pipe into individual serving dishes.

Alternately, this can be spooned into a chocolate pie crust for a mouse pie
