In London, cake maker Nastassja's pushing the boat out for her latest commission to celebrate little Noah's first birthday. Asked for a Noah's Ark themed cake, Nastassja's planning to position her revolving edible boat on a giant spurt of water made from 12 layers of vanilla sponge, topped with rice cereal and marshmallow waves. Molly's hoping to make a bit of a flutter as she creates a giant butterfly cake for a birthday surprise. Sculpted from vanilla sponge sandwiched with buttercream, she'll use all her sugar craft and air brushing skills to capture the insect's delicate and distinctive blue and pink markings in vibrant sugar paste. In Lancashire, Rosie's aiming to hit the jackpot with a working roulette table cake for a gala dinner. Taking five days to make, and built from chocolate orange cake, it comes complete with an edible life-like, highly detailed croupier!
