A new BBC show with Mary Berry will see comedian Mel Giedroyc join the cookery writer in a guest appearance.
They both starred on The Great British Bake Off before the series moved from the BBC to Channel 4.
Berry had been a judge, and Giedroyc was a presenter alongside Sue Perkins.
The cookery competition is now hosted by TV presenter Alison Hammond and comedian Noel Fielding and judged by Paul Hollywood – who has been on the show since the first series – and Prue Leith.
In BBC Two's Mary Makes It Easy, Giedroyc will appear alongside five other celebrities as they are challenged to "step out of their comfort zone, and hopefully inspire the audience".
Berry, 88, said: "I love having somebody by my side when I am cooking, and to have the celebrities was a real bonus because they all wanted to learn how to cook or to do something special for an occasion.
"I hope I gave them confidence and passed on a few tips for them."
The six episodes also see BBC Radio 1 presenter Jordan North, Strictly Come Dancing judge Anton Du Beke, Big Brother host AJ Odudu, TV presenter Lorraine Kelly and singer and BBC Radio 2 presenter Michael Ball being taught new cookery tips.
Mary Makes It Easy airs on Thursday 2 November at 7.30pm on BBC Two.
