Thank you Cathy. I cooked them at 450 for 20 minutes, then cooked for 350 for maybe another 50 minutes. Various recipes call for temperatures usually ranging from 450-500 for the initial portion of the bake, then 350-375 for the remaining portion of the bake. The key is that you can tell they are done by looking at the bottoms (uniformly dark), which are face up while you bake. Of course, you never really know if they're uniformly dark when you take them out of the oven, so I immediately unmold to check (with oven mitts of course). If not uniformly dark, they easily go right back in the molds and I put them back in the oven.
