You take a sponge cake and cut it in half and then fill the middle with fresh cream, strawberry jam and melted mozzarella cheese.
Then you get a jar of vegemite and spread it thick around the whole cake, so that is basically all covered in vegemite.
Then you get a hairdryer and hairdry the cake so that the vegemite layer becomes dry and hard.
Then you get some cooking chocolate and fill a really big saucepan with it, once it's all melted, you put the cake in (you need to have enough chocolate in their to completely immerse it) and let it boil for about 10 minutes.
You then let it set for 3 hours, then you may need to cut the cake out of the chocolate which has probably set by now.
Sprinkle the cake with dried tuna flakes and you're done!
