I meant to take it with me when I left the house, then didn't remember if I left it out or just changed my mind! I've got alot going-- wedding reception Sunday. Is there any way it's ok once baked or do I have to throw it out?

I would think if it has eggs or milk in it, it probably went bad.

I agree. Unrefrigerated life of perishable ingredients is 2-4 hours (I can't recall which/or what causes times to vary). After that, bacterial growth in the food can get way out of hand and - here's the clincher - these are bacteria that are NOT killed off by cooking. So, sorry to say, I think you should chuck it

I agree. Chuck it. Sorry that happened!

Thanks for your responses!
