What is "cake flour"?

Cake flour is a finely milled, delicate flour specifically designed for making cakes and other tender baked goods. It has a lower protein content compared to all-purpose flour or bread flour, which helps produce a softer, more tender crumb in cakes. Cake flour is typically made from soft wheat varieties and undergoes a finer milling process to achieve its light and silky texture. Cake flour can also be used as a thickener in sauces and gravies due to its low protein content. Its fine texture allows it to blend smoothly into batters and doughs, resulting in baked goods with a tender and airy texture.
