The pair were dropped by judges Paul Hollywood and Mary Berry in this week's double axing, a twist to the format after last week's non-elimination.
Chong proved impressive in the first weekly challenge of making 24 buns. However, he flopped in the doughnuts task and his enriched celebration loaf show-stopper finale - a savoury char siu bao - was frowned upon by the judges.
Meanwhile, Willis had yet another troublesome week, failing to impress in any challenge with her doughnuts, buns and show-stopper all including raw dough.
Danny Bryden was voted this week's Star Baker after impressing across all three rounds this week and wowing with a festive show-stopper.
The Great British Bake Off continues on Tuesday nights at 8pm on BBC Two.
