his16 gauge anodized aluminum round layer cake pan measures 2" diameter x 2" deep with straight sides and rolled rim for durability. There are no seams or weld lines often found in other pans.

Anodized aluminum is also non-reactive with acidic and dairy ingredients. Fat Daddio's anodized bakeware offers superior baking performance, even heat distribution, safety, and durability.
