If there's one thing that can mean the difference between triumph and disaster on The Great British Bake Off, it's never losing your nerve.
The rapper said at the start of the episode: "I reckon I'll be hosting this thing when I'm done, that's how confident I am."
He then admitted to never having watched the programme or baked anything before, but wasn't about to let that put him off.
While taking on his first challenge, a carrot cake, Dizzee refused to be intimidated by judge Paul Hollywood.
As Hollywood asked him whether he'd baked before, he replied: "Nah. It's just science, innit?"
The carrot cake was a hit with the judges, and Dizzee even spotted Prue Leith going back for seconds.
He said: "I saw Prue go for another sneaky taste. She's feeling the flavours."
After a brief meltdown over how to whisk a meringue into stiff peaks during the Queen of Puddings technical challenge, he managed to bypass competitor Nick Grimshaw in the judging and ended in a respectable third place.
During the showstopper – a biscuit self-portrait incorporating the celebrity's workplace – Dizzee even managed to rescue a split chocolate ganache by expertly whisking in some cream.
He made a biscuit version of his album cover Boy In Da Corner, with Hollywood telling him: "For someone who's never baked before, I'm amazed."
Leith said: "Isn't it amazing to think this guy had never baked before coming into the tent."
However, Dizzee's confidence couldn't quite take him to first place, which was fought out between Reece Shearsmith and Philippa Perry.
In the end it was Shearsmith, who had won a Hollywood handshake for his first cake and was told his biscuit portrait could rival the main series contestants, who was named Star Baker.
Celebrity Bake Off continues next Tuesday on Channel 4 at 8pm.
