It's all about 'girl power' this time as our extreme cake makers pay tribute to women past and present. In Lancashire, Molly is asked to represent women engineers as super heroes in a cake highlighting the contribution women have made to the world. Towering three feet high, her four-tiered red velvet cake features everything from a fondant Brooklyn Bridge to a circular saw blade, alongside chocolate super girls: all destined for the 'Young Woman in Engineering Awards'. Michelle makes a baby shower cake and Karisha celebrates International Women's Day.
