Jedan.
But be careful -- in Croatian nouns have grammatical gender and modifiers (in this case numbers) which precede them get changed accordingly.
For example, dog (pas) is masculine so it is jedan pas.
Book (knjiga) if feminine so it is jednaknjiga.
Child (dijete) is neutral so it is jednodijete.
When counting (one, two, three...) it is, as I said, jedan.
