How Cake Servings Are Calculated

Formula

Servings = Cake Area x Layers / (2 x Serving Factor)

The base serving size is a 1x2 inch slice from a standard-height layer. Multi-layer cakes yield proportionally more servings.

Exemple Résolu

A 9-inch, 2-layer cake cut into party-size slices.

  1. Cake area = pi x (9/2)^2 = 3.14159 x 20.25 = 63.6 sq in.
  2. Servings = 63.6 x 2 / (2 x 1) = 63.6, rounded to 64 servings.
  3. Batter needed = 63.6 x 2 x 0.07 = 8.9 cups.
