Noel, Fielding, Sandi Toksvig, Prue Leith and Paul Hollywood return to the tent for a traditional Christmas get-together and welcome back eight former contestants to compete once more. In this first of two editions, Paul Jagger (2015), Beca Lyne-Pirkis (2013) and Selasi Gbormittah and Val Stones (both 2016) face three festive challenges as they compete to impress judges Paul and Prue in the signature, technical and showstopper rounds and carry off the coveted title of Christmas Star Baker.
