Jelly babies were an English sweet favoured by the Doctor, his fourth incarnation in particular. The Doctor often offered them to companions and others he met on his travels. Jelly babies were in the shape of a miniature humanoid child. They were made out of gelatin and were available in a variety of colours and flavours including chocolate. (GAME: City of the Daleks) Colours included green, orange, black, pink (PROSE: Utopia) and red. (AUDIO: Scaredy Cat)
At one point, the company that made jelly babies decided to discontinue production of the pink jelly babies, unaware that it was a favourite colour of their customers. The company began to lose profits and eventually went bankrupt. (PROSE: Utopia)

Behind the scenes
Jelly Babies are a real-world product sold under that name since 1953 (existing long before their association with Doctor Who), and under other names many years before that. They are similar to gummi candies.
On Tom Baker's official website, an overview of Tom Baker's tenure as the Fourth Doctor by writer Nicholas Pegg claimed that the original script of The Face of Evil involved the Fourth Doctor threatening the tribesmen with a knife. Feeling that such an act was not appropriate, he insisted that the Doctor bluff his way out with a jelly baby instead.
In the United States, jelly babies had a low profile as a confectionery product. When Pinnacle Books published Doctor Who novelisations in new packaging, the editorial changes made by them included changing jelly babies to jelly beans, for fear of confusing American readers. Later, when the series had a great deal more popularity, many Americans simply associated jelly babies with Doctor Who and with the Doctor as played by Tom Baker. Under license from the BBC, one company sold jelly babies in packaging resembling the Doctor's TARDIS, advertising them as "the Cosmic Candy of the Time Lords".
Jelly babies appear as collectible cards in The Adventure Games.
