The popularity of baking has left us a nation clamouring to try it ourselves, but for those show-stopping cakes only a few can rise up to the challenge. For one lucky little birthday girl, Extreme Cake Maker Michelle Wibowo is creating a five foot edible Wizard of Oz mural out of Genoese sponge and covered in painted icing and sweets. Meanwhile, Nastassja Lusengo is bringing out the bling - decorating one of her famous red velvet cakes in edible gold leaf while Cornish based bakers Phil and Christine Jensen are creating a four-tier cake inspired by the Queens House in Greenwich, complete with 28 edible tulip decorations.

At the heart of any extreme cakes lies a brilliant idea and, when it comes to dreaming up these original designs, 31-year-old Nastassja Lusengo knows the sky's the limit. She's been commissioned by a client to produce a cake for her brother's wedding, inspired by a geode rock and will split open to reveal shimmering sugar crystals carved into the cake's interior. Essex's Eloise Durrant has a totally different challenge on her hands - producing cake for a Hawaiian themed party that includes a fully working cocktail dispensing water feature, four tiers of cocktail flavoured sponge cake and is decorated to look like a Pacific volcano.
