Pour fresh cream into a hot non-stick pan. Stir it well until it comes to a boil. Place dark chocolate in another bowl. Once the cream boils, pour it over the dark chocolate and blend it well to prepare the chocolate fondue. Add a little red chilli powder. Transfer this mixture to a serving bowl. Finely chop apple, orange, chocolate cake and vanilla cake into bite size pieces. Pin the chopped fruits, marshmallows and cakes on skewers for dipping in the fondue. Have your chilli chocolate fondue with fruits and cake.
