I've always been a cupcake maker but for the OH's birthday I've decided to bite the bullet and make a cake! I've seen this cake:



And want to have a go at recreating it! My mums pretty nifty at covering cakes with icing so she's going to help with that bit, and I'm going to make the log cabin out of cake and then cover it in matchstick (the chocolate ones) to look cabiny. Also got a local company making the little skier

My issue is with the main bit of the cake! I thought I could just make a load of sponges and stack them, and then carve them into the shape of the mountian. But will this work, or does it need internal support? I know with wedding cakes you would put dowels and plates, but as this is not a normal shape I'm not sure how it will work?

Does anyone have any hints and tips on this one please?[/img]

Internal supports are needed for every 4" of cake height.

Watch some or the utube videos on stacking cakes. Each layer needs its own cakeboard. Good luck.
