I seem to remember Harry Potter getting food for his birthday. What food(s) did he get and from whom?
In Philosopher's Stone (As apporv020 notes in his answer), Harry was given a large, sticky chocolate birthday cake with green iced lettering by Hagrid.
In Chamber of Secrets Harry receives nothing for his birthday because Dobby is intercepting Harry's mail.
He doesn't receive food in Prisoner of Azkaban, unless The Monster Book of Monsters could be considered edible, which I think not.
In Goblet of Fire (as Pearsonartphoto notes in his answer), Harry receives four superb birthday cakes from Ron, Hermione, Hagrid, and Sirius respectively.
In Order of the Phoenix, Harry receives two boxes of Honeyduke's best chocolate from Ron and Hermione, but ends up tossing them out in a fit of pique when no one writes or contacts him during the summer holidays.
In Half-Blood Prince Mrs. Weasley has a birthday tea for Harry with birthday cake.
In Deathly Hallows Mrs Weasley gives Harry a birthday dinner complete with a large beach ball-sized birthday cake decorated as a Golden Snitch.
These are all the birthday-related food references I could find.
The most conspicuous example occurred in book 4, where he got food when Dudley was forced on a diet. This included cake and other junk type foods for the most part, from Hagrid, the Weasleys, Hermione, and Sirius, I believe.
Also include the chocolate cake on his eleventh birthday.
