Sweet and chocolate quiz

[ladyh]

The clue indicates the name of a sweet or chocolate, I don't know the number of letters I'm afraid.
1. Is it made of corn or soap?
2. Additional payment for a job well done.
3. Nutty way to urge on a horse.
4. Calls a halt to talking slang.
5. Rarely in the papers.
Thanks in advance for any help.

Thank you emeritus, johnalex, gen2 and JMR27. Emeritus - I wondered abour Bonus - as it fits so well with the clue, but having searched the internet have only found a posting from someone saying they thought there was a chocolate bar called Bonus some time ago.
I had an idea that it might be Dime, but my husband informs me that this is now called Daim, which doesn't work.

I have had a look and have to agree Ladyh, I must have dreamt it !!

So how about Bounty instead ?
