My parents had a German bakery in Chicago when I was growing up.
First of all, we went to Germany, Austria and Switzerland every three years when I was a kid, to visit my grandparents. And to keep our German up to par.
The bakeries there are beyond first class. There is NOTHING the US has to offer anywhere that can compete. Their ingredients are simply finer. Better eggs, richer cream, flours that are finer for pastries. Etc.
My father, who was trained in Germany, used to complain about this issue all of the time. And it went far beyond just quality differences. If he wanted to, he could have gotten the best of everything and made things for sale at unaffordable prices. But the bigger problem was that the American government regulates the types of ingredients that can be used in baking. For example in Chicago, the Board of Health made monthly inspections; my dad used to pay them off, so he could use fresh eggs that he bought especially from a farmer in Indiana. The Board of health wanted you to used homogenized pasteurized eggs that came in giant buckets and were vile. My dad said this kind of thing accounted for the sorry state of baked goods in American bakeries. He used fresh butter, eggs, flour, cream. He had many ingredients sent to him from Germany and he baked for the finest establishments in Chicago, including the best hotels and the fanciest restaurants.
But he also had different levels of deliciousness. If the birthday cakes were just for sale in the store, buttercream was made of shortening and margarine. If the cakes were to order and at the highest price level, they were all butter and cream.
So, Geneva Switzerland person, you can still get great birthday cakes, but mainly from home bakers. I bake cakes for sale out of my home and they are the most fabulous of the fabulous. I am a scientist, so this is a sideline. Mainly wedding cakes.
You can get really great cakes from cake bakeries who specialize in making only cakes, but they are not the birthday cake crowd. These are wedding cake and specialty cake establishments that charge about $15/serving. Mainly, I think, people who bring birthday cakes to office parties, or to surprise parties, are still getting them from places like Wegmans or Stop n Shop.
