How do you prefer to spell it? I can't think of a common English word with more possible spellings. Wikipedia: In English, there are several variations of the spelling of the word, including yogurt, yoghurt, yoghourt, yogourt, yaghourt, yahourth, yoghurd, joghourt, and jogourt. In the United Kingdom and Australia, yogurt and yoghurt are both current, yogurt being more common and used by the Australian and British dairy councils, and yoghourt is an uncommon alternative. In the United States, yogurt is the usual spelling and yoghurt a minor variant. In New Zealand, yoghurt is preferred by the New Zealand Oxford Dictionary. In Canada, yogurt is most common among English speakers, but many brands use yogourt, since it is an acceptable spelling in both English and French, the official languages of Canada.
