9-inch round is the standard layer-cake size in American baking — birthday cakes, anniversary cakes, the layered chocolate cake your grandmother used to make. Two pans means you bake both layers at once instead of waiting for a single pan to cool, scrub, and re-grease. Corrugated bottom creates air channels that brown the cake evenly without burning the bottom.
Reach for these for any 9-inch round recipe — sponge cake, devil’s food, white cake, vanilla bean, carrot cake. Also doubles as roundbread pans for sourdough boules or mini casseroles.
