This cheap metal plate fixed our cupboard hinge where it had pulled away from the cabinet wall. I'd tried putting toothpicks (matchsticks are the other suggestion) into the hole & it only worked for about a week before breaking again.

You must check the dimensions of the cupboard hinge you've got before buying anything.. make sure it's the right size and fits your hinge; mine hasn't got the circular indentation that a lot of cupboards do, so do your research & make sure you get the right one for your cabinet.
