She wanted to split a snack... was this just being nice?

We were on a break at a conference. She waited until everyone else had left and then asked me (kind of in a whisper) if I wanted to split a danish. My initial thought was that this was a sign she wanted to maybe kick our friendship up a notch and want to ask her out. But now I'm second-guessing. Would you split something with just anyone?

Since we don't work together but do know a lot of the same people professionally, it's kind of a weird gray area. I did ask her to lunch and it looks like that's going to happen. I guess that's a good sign. But now, do I buy?
