The mother-of-three from Leeds won the 2015 series of the BBC One show on Wednesday night, beating trainee anaesthesiologist Tamal Ray and photographer Ian Cumming in a tense finale.
Speaking to The Sun, public relations expert Mark Bourkowski said: "Nadiya winning is the dream ticket. There is a massive opening for her as a role model. The commercial potential is huge. Recipe books, food endorsements, deals with big brands, a line of restaurants. This could be bigger than £1 million."
Dominic Mohan, CEO of PR company The Outside Organisation added to Daily Mail: "The earning potential is huge as previous winners have shown, from newspaper and magazine deals to endorsements and public appearances and then on to cookbooks and maybe even their own restaurant.
"In terms of earning power and with the right representation and of course personality, winners could in the first instance be looking at half a million pounds with the potential to reach the million mark as their career develops.
Interestingly, winners of Great British Bake Off don't actually get a prize from the show other than the glass cake stand Nadiya was seen brandishing last night.
