Are aluminum cake pans non stick?

Yes you can. I make full size sheet pan (18 x 26) PineApple Upside Down Cakes. The techique I use is to first spray the sheet pan with nonstick cooking spray. Then I place the aluminum foil over the sheet pan allowing it to be at least a inch higher then the edges of the sheet pan. The foil keeps the mixture from spilling out when using a shallow sheet pan. After baking I let it cool down and then flip it. Peeling the foil carefully off the cake.
