DS1 is 5 on Wednesday. He is having a pirate party and I have decided to make him 2 cakes. One is a treasure chest filled with choc coins, dextrose 'jewellery' and I am fairly confident that I can make it without mangling it too much. maybe too optimistic
The other is a pirate ship 
I need a recipe for a chocolate sponge which will be easy to work with-firm enough for me to cut it up and stick it together with icing, then load it with masts, paper sails, choc cannonballs and playmobil pirates!
Other than needing a recipe, I also wondered if I could bake the cake say on Monday, decorate on Tuesday, then serve on Wednesday? Will it be stale under 15 feet of icing?
If I put it in the fridge will the condensation wreck it?
God, I have totally overestimated my abilities!! Any advice will be gratefully received
