The Great Sport Relief Bake Off (2014) Episode 4

It is Ed Byrne's turn to take up the baking baton and support the four celebrities as they face their three challenges in the Bake Off tent. The bakers on the starting line are impressionist Alistair McGowan, Saturdays singer Rochelle Humes, comedian Doon Mackichan and former Blue Peter presenter Helen Skelton, who rowed the Amazon and trekked to the South Pole for Sport Relief. Will her baking prove as much of an ordeal? The bakers must make pizzas for their signature challenge, eccles cakes in the technical challenge and showstopping tiered cakes that represent sporting equipment.
