I like the idea of packaging your cookies. Think of a nice name to out on and may be a one line slogan or something.

Something like you can name your cookies smile cookies or Happy Memories

Your slogan can be - Make your visits memorable (for hospitals name and slogan should be different atleast slogan if not name)

You can also make a deal where you charge extra to make custom packaging for agents/ hospitals / cafes with their brand names at an extra cost (with subtitle line of manufactured by your business name and address email id)

For reaching out people put an ad in magazines that are read by Realtors with Headline

How To Make Your Customers Remember You Without Spending on Ads - An age old trick used by women to woo men

Ask them to leave their name and email id

After receiving the info send them the info on email on how making people eat food is one of the best and inexpensive ways of winning people over and make them remember you.

With your cookies you can do the same. Talk about your custom packaging option and how it will help them increase increase their conversion, customer retention and increase in business.

Ask them to schedule a free Tasting Demo where you can showcase your cookies and let then taste them. Have a brochure and give them different options and close the deal.

Hope this helps.
