Best Baked Goods that can be shipped?
quick breads (to make them special sprinkle cinnamon sugar all over the insides of pan before pouring in batter. you'll get a really nice sweet "crust" )
pound cakes - lemon, chocolate, whatever
i haven't done this but what about baking rolls with dark chocolate in it, you know, like chocolate croissant only using a sturdier bread.
cookies that you stack in a ziplock and then slide into a wine tube with a bit of stuffing at each end. you know, those cylindrical wine gift boxes.
To be clear, do you mean that you want to order nice baked goods or make your own?
When my niece was on a student exchange in Germany, I send various baked goods in plastic containers I bought at a dollar store. Most things arrived in very good shape, particularly banana loaf or scones. The post office has a special padded envelope that was about $14 for 2-3 day delivery to Germany that perfectly fit a 8" X 4" container that was about 1" high.
