In a bowl, mix the white caster sugar and mascarpone until smooth and set aside.
In another bowl, whip the heavy cream with the vanilla sugar and stabilizer until stiff. Set aside a bit of whipped cream for topping.
Gently fold the whipped cream into the mascarpone mixture and place in the fridge.
Break the Kinder Bueno bars into pieces, mix with cocoa powder, and fold this into the mousse.
Spoon the mousse into a piping bag and fill 4 glasses almost to the top. Place in the fridge to chill for at least 1 hour.
Decorate each glass with a dollop of whipped cream, a drizzle of chocolate sauce, and a piece of Kinder Bueno.
