Cake tin sizes

As a rule of thumb, a square tin holds about 25% more than a round tin of the same size. If you're using a square tin for a round tin recipe, keep the temperature the same, and turn the cake during baking, as the corners tend to cook faster than the middle. Be inspired by our easy cake recipes.
