A zip wire, a space hopper and ducklings - it's just another day for our Extreme Cake Makers. Karisha's pushed to extremes by an edible assault course with a working zip wire for a 12th birthday. This adventure playground will feature edible tree tops, rope bridges and a working zip line. Molly makes a splash with a stunning three foot-wide floating duckling cake with an edible landscape. Meanwhile, former army helicopter pilot Rosie goes retro with a Space Hopper cake. At two and a half feet tall, this chocolate orange masterpiece includes 20 kilos of fondant icing and is set against a graffiti wall backdrop.
