Melt Chocolate and butter together in a bowl over boiling water. Allow to cool slightly, then stir in cocoa powder until smooth.
Add sugar, aquafaba, peanut butter and vanilla essence, and using a hand held mixer, combine until smooth and most of the sugar has dissolved. Add flour and salt, and continue mixing until a thick batter has formed.
