It's Cake Week! 12 of Australia's best amateur bakers are back in the Bake Off shed for their first week of challenges, under the watchful eyes of culinary icon Maggie Beer, and esteemed chef Matt Moran. This week, the bakers will tackle a signature sponge, a tricky technical Japanese Cotton Cheesecake, and for their showstopper, create their own Miniature Worlds. One will be crowned the week's Star Baker, and one will head home.
