These versatile professional cake pans are designed for baking a 3-tiered party cake using one standard cake mix. Straight sides produce professional-looking cakes with straight edges, essential for layering and decorating ease. The pans' uniform wall thickness results in an even rise and the elimination of hot or cold spots in cakes. The anodized aluminum pans won't discolour and provide excellent cake release and clean up. A .25" round rim makes it easy to lift and move the pans without disturbing the contents.
