How to Substitute Cake Pans

Formula

Round Pan Area = pi x (Diameter / 2) squared

Rectangular Pan Area = Length x Width

Batter Ratio = Substitute Area / Original Area

When switching pan sizes, the key is matching the total batter volume to the pan area. If the substitute pan is smaller, you will need to reduce the batter (or use multiple pans). If it is larger, the cake will be thinner.

Baking Time Adjustment

A thinner cake bakes faster. Reduce baking time by about 5 minutes per inch of reduced depth and check early.

Exemple Résolu

Substituting a 9-inch round pan with an 8-inch round pan.

  1. Original area = pi x (9/2)^2 = pi x 20.25 = 63.6 sq in
  2. Substitute area = pi x (8/2)^2 = pi x 16 = 50.3 sq in
  3. Batter ratio = 50.3 / 63.6 = 0.79
  4. You need about 79% of the recipe or 2 pans to hold the full batch.
