Cake flour is the delicate, low-protein darling of the baking world. It makes your cakes, muffins, and scones fluffy, tender, and light—like a soft, edible cloud. Regular all-purpose flour has more protein, which creates more gluten, and that can make your cake dense or chewy. Think of it like the difference between a cozy wool sweater (all-purpose) and a silky cotton blouse (cake flour).
A simple trick that works every time
You can turn regular flour into a cake flour substitute with just two pantry staples: all-purpose flour and cornstarch. It’s like a little kitchen magic trick that takes two minutes. For every one cup of cake flour you need, simply measure out 1 cup of all-purpose flour, then remove 2 tablespoons of it.
Add those 2 tablespoons of cornstarch back into the flour. Sift it all together at least three times—this is key—to make sure the cornstarch is evenly spread. The cornstarch lowers the overall protein content, mimicking the gentle touch of real cake flour.
