The Great British Bake Off is on BBC One tonight for a festive Christmas special.
The tent has been decorated and the invitations have been sent out for two very special Christmas episodes of The Great Christmas Bake Off.
Eight bakers of Bake Off past will return to the tent over the two shows to compete once more.
In this first episode there's another chance to see Mary-Anne from Series 2, Ali from Series 4, Cathryn from Series 3 and Norman from Series 5.
Just as in the main show, the bakers face three challenges but each with a special festive twist.
As always, starting with the signature challenge, Paul and Mary ask the all star bakers to make some highly decorative Christmas bakes that require intricate icing.
For the technical challenge, Mary has set the recipe and gives the Christmas bakers the special present of mystery ingredients and a recipe which, if the bakers follow correctly, will produce a stunning bake, decorated with chocolate snowflakes.
And finally there is the showstopper, for which the bakers must produce a festive masterpiece with a Christmas theme.
At the end of the show, judges Paul and Mary will retire to decide which one of the All Star bakers deserves the special title of Christmas Bake Off champ.
The Great British Bake Off, BBC One, 4:45PM, Christmas Day.
The Great Christmas Bake Off returns tomorrow (Boxing Day, 7PM) for another episode, this time with Chetna from Series 5, Howard from Series 4, James M from Series 3 and Janet from Series 2.
