Yankgal46 - here's the recipe I followed (video)http://www.youtube.com/watch?v=w6lXjl1wWwc
It's basically 3 eggs (separated), 1/4 tsp cream of tartar, dash of salt, 3 oz cream cheese. I then added 1-2 T of parmesan, dash of garlic powder and 1/2 tsp of oregano to the egg yolk mixture. There are other minor variations on the web.
And thanks evelyn, I actually have a lot of problems with my oven so it wouldn't surprise me if the temp was off. Next time I'll try baking them longer.
