That seems likea pretty feisty kitty! When I first got my guinea pigs, Smudge was a bit of a nipper. When he would nip me, I tried lightly tapping him on the nose. Soon afterwards, he stopped the habit. My family has cats and I am always around them, but I am not entirely sure this trick will work. So maybe you could tap her nose and say "No" loudly, possibly that could break the habit. Hope it helps
