MORE 'BAKE OFF':
According to overnight ratings, the peak at 8.55pm was watched by 14.5 million, beating last year's figure of 13.3 million.
Overall, an average of 13.4 million viewers tuned into the 2015 final, compared to 12.3 million in 2014. This year's final has also become the most watched non-sport programme on a Wednesday night since Christmas Day 2002.
The 'Great British Bake Off' scored its highest ever audience for Wednesday's final
BBC One's popular baking series has now replaced the May 30 final of ITV's 'Britain's Got Talent' as the most watched show of 2015. It has also pushed the live "who killed Lucy?" reveal episode of 'EastEnders' broadcast on February 19 into third place.
'Bake Off' champion Nadiya has her husband to thank for pushing her to apply for the show, when she believed she had no chance of making it on to television.
The stay-at-home mother walked out of the 'Bake Of'f tent "a much stronger, confident person" after being crowned winner of series six, beating Ian Cumming and Tamal Ray in an emotional final which had judge Mary Berry in tears.
The 30-year-old, who became loved for her expressive face, said it was "surreal" to finally be able to talk about her achievement after keeping her win on the BBC show a secret.
She told 'BBC Breakfast': "It feels like I'm reliving that moment again. It was one of the best moments of my life.
"My husband (Abdul) tried to get me to apply two years ago and I said, 'look, I don't have the confidence to do something like this', and this year he pretty much forced me and said, 'you're really good, you're really clever, you should just do it, what's the worst that will happen?'.
"Those were famous last words. And I did it, and I went in and I applied and every stage of the process felt unlikely and like it wasn't meant to happen.
"My confidence grew and then this happened."
Nadiya beat Tamal and Ian to win 'Bake Off'
The mother-of-three described how she "comes from a culture where there is no such concept of dessert after dinner" and she caught the bug for baking during home economics.
Born in Luton to a Bangladeshi family, Nadiya has been praised as a role model for young British Muslims after previously admitting she was nervous that audiences would "look at me, a Muslim in a headscarf, and wonder if I could bake".
The Muslim Association of Britain said of her win: "Her participating in The Great British Bake Off has demonstrated the connection that young British Muslims have with British society."
For her final challenge she created the wedding cake she missed out on at her own wedding in Bangladesh, which she decorated in a red, white and blue sari, the colours of the Union Jack.
Nadiya said: "I went into the tent as the smallest baker at 4ft 11in but I walked out feeling a giant - almost as tall as my fellow baker, six-footer Mat Riley."
