I have had trouble with foil when making something that would go up into all those little crevices. I found that the batter goes into the crevices and sticks like crazy, even if I spray with a Pam type product or use grease. Then the cake or whatever tears all up when I try to get it out. Plus you can't run a knife around it to loosen it up if you need to like you can do in a smooth surface cooking pan. Any smooth surface would be a much better choice.
