Using a square cake pan for round cake pan recipe

If you have a recipe for a round cake and want to bake it in a square tin, use a square tin which is 2.5 cm (1 in) smaller than the round tin size.

For example, the recipe for a 23 cm (9 in) round cake could also be used to make a 20 cm (8 in) square cake. Halving the quantities given for the 23 cm (9 in) round recipe will make a 12.5 cm (5 in) square cake or doubling the quantities will be sufficient for a 28 cm (11 in) square cake
