Running low on cake flour? Here are the best verified substitutes, including how to adjust your measurements.

About cake flour
Cake flour is a finely milled, low-protein wheat flour with a protein content of around 7–9%, giving baked goods an exceptionally tender, fine crumb. Its lower gluten-forming potential prevents toughness, making it ideal for delicate cakes, biscuits, and pastries. The flour is often bleached, which further weakens gluten and allows it to absorb more fat and sugar.
Best substitute
Replacing a portion of plain flour with cornflour (cornstarch) dilutes the protein content, closely mimicking the low-gluten properties of cake flour. Sift together well to ensure even distribution before using.
Alternative
Plain flour (all-purpose flour) can be used directly as a substitute, though the higher protein content will produce a slightly denser, chewier crumb. Best used when cake flour is unavailable and texture is not critical.

Alternative
Self-raising flour has a similar low-protein profile to cake flour and can work well, but you must reduce or omit any baking powder or bicarbonate of soda called for in the recipe to avoid over-leavening. Check the recipe's leavening carefully before substituting.
Alternative
Pastry flour sits between plain flour and cake flour in protein content at around 9%, producing a tender result that is slightly more structured than cake flour. It is a good substitute when a little more body is acceptable.
Alternative
White rice flour is very low in protein and gluten-free, making it useful for those with gluten sensitivities. Blending it with plain flour or a gluten-free flour mix can approximate the tenderness of cake flour, though the texture may be slightly grainier.
