I wouldn't, no offence, advise giving any sort of reward for this behaviour at all. In your mind you know you are rewarding her for being quiet - in the dog's mind not only is she getting attention for making a disturbance she is also getting treats.

I would move the dog bed out of the bedroom and shut the door. Settle her as usual when you are ready to go to bed and then leave her. DO NOT go back to her - no matter what!
As long as you 100% ignore attention seeking from the other side of the door she should settle down within a week. If she doesn't - get back to me as I am working with a client on a new idea for a similar problem and if it works it may help you also.
