Does it mean anything if a girl offers you food?

I sit next to a girl from China in my biochemistry lecture. I think she's pretty cute, and we flirt from time to time. Starting two weeks ago, she's been offering me snacks at the beginning of every lecture we have together. The snacks she offers are these delicious cream-filled Chinese cookie things (I don't know what they're called, since I can't read Mandarin). Sometimes she offers me these panda-shaped cookies (again from China, so I don't know what they're called). She doesn't offer them to anyone else.

I'm not sure if she's just being friendly, or if offering food means anything more than simple friendliness.
