I'm not at all familiar with the non-durables market, so take this with a grain of salt. But I am somewhat familiar with the luxury goods market. Your biggest challenge is going to be finding a way to make them as good as they are at home, but with a much longer shelf-life. Find other companies who do this well, and figure out who does their manufacturing.
What is your price point? I'm assuming that you're going after the luxury goods market? Major retail stores already have "X" linear feet of shelf-space allocated to "Y", in your case, ready-to-eat baked goods. Buying your product means that they will either have to increase that allocation, or cannibalize something that's not doing as well for them.
I wouldn't typically recommend this, as it will cut into your margin significantly. But I would set up a booth at regional gift markets, and cater to the boutique gift shops. This is always one of the busiest sections of a trade show / market because the buyers love the free samples! It's hard to make marketing recommendations without knowing more about the product, but I would also strive to get some free press by promoting them to magazines' gift-giving editions.
The problem with grocery store chains is that most of them already have a bakery. I'm assuming your price point will be higher, so you'll have to carve your own niche of exclusivity, using the "Old World European" charm angle. My 2 cents.
