James Acaster: Never baked before. Let alone competitively. Let alone on Bakeoff. It's the worst idea anyone's ever had. Paul Hollywood: The texture of your flapjack-- >> It is perf. >> --on the top, it looks a bit wet. >> Oh yeah, that's 'cause it's not baked yet. [Prue and Noel laugh] >> Ah. I can explain this to you. Before it goes in the oven, it's often a lot soggier. >> Right, ok. >> Is the texture ok? Good joke! Wanna shake my hand now or later? [Music] >> Up to you. You can shake it now to save yourself the bother, or you can shake it later on and eat humble pie as well as these flapjacks. Sandy Toksvig: Bakers, you have half an hour. [Music] [Oven clatters] >> Right, I wish I were dead. [scoffs] I'm not taking that out the oven. It's like a soup. [Music] >> Come on. Be magically done. The mixture is...still liquid. This is meant to be encouraging people at home to get involved and bake for charity. This is the worst experience of my life! This is so bad. [Music stops] >> Can you tell us about your flapjack, please? >> Started making it, had a breakdown... bon appétit! [Laughter] >> Bit of a small bit. Up to him. >> The reason I cut the end bit is 'cause actually, where it's browned and caramelized with the butter, it's absolutely gorgeous. >> So delicious. Isn't it lovely? >> It is. Great flavor, not very well executed. >> Story of my life. [Laughter] >> I thought even if baking goes badly it's a bit of fun. It's not. No, not disappointed--scarred. [Water splashes into the bowl] >>Oh, too much, that's too much. This seems absolutely absurd. That is too much frozen butter. So, I've go excess dough. Rylan Clark: You shouldn't have excess dough, no >> But, I cut it down to the size it says here. I don't-- >> No, you use the whole dough together-- >> Yeah >> And make that that 10 centimeters by 25. >> Well, it's too late, now, so I'll-- I'll put the butter in. Noel Fielding: Where are the rest? >> Oh, let's be realistic. [Noel laughs] [Music] [Music stops abruptly] >> Who is responsible for this? Well, all I can say, is it does have the ingredients we gave you there. >> What more could you ask? [Laughter] >> Quite a lot more. >> We would like you to make a meringue scene. Basically, your happy place. >> Cowabunga! Surf's up! I'm baking my happy place, which is Wicksteed Park, which is Kettering's premier theme park. Russell Tovey: Do you want some salt? I've got some salt. >> I'd love it. Thank you, Russell. Just making my meringue taste like the ocean. [Russell scoffs and laughs] >> Shouldn't really go in freehand, should I? But-- would someone who plays by the books do this? [Music] >> Wiki bear, reclining on the ocean. I'm icing a raw egg. Does the name Prue mean anything to you? I know I'm in danger of constantly adding to perfection, you know? [Music] >> That is the roller coaster in meringue. It's sweet egg flavor. [Laughter] >> Sweet egg? >> Now, see if you can spot the secret ingredient in the water. >> No, is the answer. >> I put a little salt on it, for a laugh! [Laughter] >> You're right, there is a hint. >> I quite like it, actually. >> It's like salted caramel. It's true. >> I think it's brilliant, James. >> Thank you very much, Paul. [Applause]. Thank you very much. Paul kinda gave me a look during that showstopper that let me know: Obviously, we can't give it to you, but you are Star Baker. [Music]
