Past halfway in their baking marathon and the remaining six bakers face three European cakes. For their signature challenge the bakers are asked to bake yeast-leavened cakes, and Mary sets the bakers their most demanding technical challenge yet in which they must make a Swedish princess torte.

It's the quarter-finals of the Bake Off and only five bakers remain. Asked to make enriched sweet fruit loaves for their signature challenge, the bakers must work with soft dough to create works of art for Paul and Mary to critique. The technical challenge stretches them to the limit and finally, a show-stopper that takes the ordinary into the extraordinary.
