Cake flour is a finely milled flour that is low in protein and gluten, making it ideal for delicate, light-textured cakes. In Australia, cake flour is also known as soft flour, biscuit flour, or pastry flour. It is different from plain flour, which has a slightly higher protein content of around 9-12% .

If you cannot find cake flour in Australia, you can make a substitute by mixing all-purpose flour with cornstarch. To make one cup of cake flour substitute, remove two tablespoons of all-purpose flour and replace it with two tablespoons of cornstarch.

Cake flour is not only great for cakes but can also be used in other baked goods such as pancakes, biscuits, muffins, scones, lamingtons, crepes, and crumbly pastries.

If you want to purchase cake flour in Australia, it is available in some specialty baking stores and online shops such as Latorta, which stocks premium cake flour by Allied Mills.
