Frequently asked questions

How do I convert an 8-inch round pan to a 9-inch pan?

An 8-inch round pan has an area of ~50.3 sq.in. A 9-inch round pan has an area of ~63.6 sq.in. Multiply your recipe ingredients by 1.27× (or ~25% more batter) to fill the 9-inch pan to the same depth.

Can I bake an 8-inch square cake in a 9x13 pan?

An 8x8 inch square pan has an area of 64 sq.in, while a 9x13 pan has 117 sq.in. You need 1.83× (almost double) the recipe batter to fill a 9x13 pan.
