The technical challenge proves exciting for hosts Sam and Mark as it's their favourite pudding - jam roly-poly - and the showstopper sees the young bakers creating an inside-out cake. But for two it will be their last time inside the Bake Off tent as judges Allegra McEvedy and Graham Hornigold decide who will go through to the next round.

Five young bakers are challenged to prepare a meringues-en-bouche - a wedding centerpiece which requires more than one hundred multi-coloured meringues - and show stopping mini tarts as they battle for the last three places in the semi-final.

It's the semi-final and the remaining young bakers have their knowledge put to the test in a series of tough technical challenges, which include replicating Graham Hornigold's piping skills and rectifying the deliberate mistake in Allegra McEvedy's blueberry muffins. Only four will make it through to the final.

The last four bakers face their first signature challenge. While the challenge itself isn't a surprise, the celebrity guests who they are baking for are. Judges Graham Hornigold and Allegra McEvedy aren't making it easy for the finalists in the technical challenge as they set the bakers extremely tough rough puff pastry pinwheel pastries.

The four remaining contenders face the last challenge - creating a tiered, layered show-stopping enchanted woodland-themed cake.
