I've never made a cake like this before so I need some experienced bakers help.
My plan is to make a chocolate cake (4 x square cakes) and then build them together with jam and whipped cream (dd2's request as she doesn't like buttercream or chocolate spread - any other suggestions?) then cover it in melted chocolate (it's got to look like a desk) and use flake to make it look like grooves in the wood (and to add to the taste) then on the desk she want it to look like pieces of paper with happy birthday and a childs drawing with paintbrushes, crayons etc (I plan to use ready to roll icing to mould the paintbrushes, a palette and crayons as well as paper) I'll use the tubes of coloured icing to draw on the "paper" I've also ordered some crayon candles.
My problem is her birthday is saturday I don't want to spend all day in the kitchen so I would like to make it in advance but because of the whipped cream only lasting 3 days I'm wondering how I can work it?
The royal icing says its not to be put in the fridge but the cream and chocolate will need to be in the fridge?
I've got time on Thursday day time while dc's are at school to bake the cakes, and model the stuff i need out of icing.
I could put it all together on the Fri evening would that work but then where do I keep it overnight, in the fridge and ruin the icing or on the side in a tub and ruin the cream filling? Or should I convince dd2 to have a different filling and i'lkl make her whipped cream to go on the side on the day?
