I'm not expert but I reckon at this age her nutricionial requirements should be covered during the day, she shouldn't need feeding at all during the nighttime...maybe she is just thirsty? Try giving her water everytime she wakes up.

Otherwise, horrible as it sounds, maybe you can just let her cry it out. 1 year babies know how to use crying not to only to communicate basic needs but just to get some attention. Perhaps if you ignore it for a couple of nights, she will learn that crying at night will not get her what she wants (your attention) and realise that nights are for sleeping.

hope it helps
