DBX80 I don't remember the particulars of your sitch, I would need to go back and reread. But yeah the cupcakes are just that, cupcakes. Nothing more, nothing less. I wouldn't make a special attempt to contact her to thank her. Next time you need to text about the dogs just throw in a "Oh, and thanks for the cupcakes."
If she is still trying to be friends, then it was likely a friend giving another friend cupcakes. And as the other said, probably a temp check thrown in to boot.
