Adjust oven rack to middle position and heat oven to 350º.  Butter bottom and sides or line with parchment a 9 1/2 in springform pan.  Melt butter, chocolate and espresso powder in a large bowl set over a saucepan filled with 1 inch of barely simmering water, stirring occasionally until smooth .  Remove from the heat and cool for 5 minutes.  Whisk in the egg yolks and vanilla.


In a stand mixer fitted with the whisk attachment, beat egg whites and salt until frothy.  Add half the white sugar and beat until combined.  Add the remaining sugar and beat at high speed until soft peaks form.  Using rubber spatula fold half of egg whites into chocolate mixture to lighten.  Fold in remaining egg whites until no white streaks remain.  Pour into prepared pan and smooth with offset spatula.  Bake until edges are set and middle is soft, 13-18 minutes.  Transfer to a rack and cool completely in pan, about 1 hour.

Whisk cocoa powder mixture into melted chocolate .  Using rubber spatula, fold half the whipped cream into chocolate mixture.  Add the remaining whipped cream and fold until no white streaks remain.  Spoon mousse into pan over cooled cake and gently rap on the counter to remove any air bubbles.  Spoon the top with an offset spatula.  Clean the sides to remove any drips or smears.  Refrigerate for at least 15 minutes.


In a small bowl, sprinkle gelatin over water;  let the stand at least 5 minutes.  Place white chocolate chips in a medium bowl.  Bring 1/2 cup cream to a simmer in a small pan over medium heat.  Remove, add gelatin mixture and stir until dissolved.  Pour hot cream over white chocolate chips and stir until chocolate is melted.  Cool to room temperature, about 5-10 minutes.
