Momiji barks when I leave each morning.

She will stop barking when I shut the door but she will start barking even before I'm ready to leave. (hence I leave earlier and earlier lately....)
She sense that I will be leaving soon and she starts to bark at me.
How do I stop her from barking??
I give her a frozen cottage cheese, her favorite treats, piece of chicken, still she chose barking over her food.
She will stop as soon as I close the door so I am not too concern but I was wondering if I can correct her.
Any suggestion???
