Cake flour is finely milled soft wheat with a low protein content of around 7 to 9%, giving a tender, fine crumb in sponge cakes, chiffon cakes, and biscuits. One metric cup (250 ml) weighs around 130 grams or 4.59 ounces. When a recipe calls for cake flour in cups but you only have scales, converting by weight gives the lift and softness the recipe expects.

Cake flour is sold in 1 kg or 500 g bags, while recipes mix cups, grams, and tablespoons. Weighing in grams gives more consistent results than scooping the powder-fine flour into a cup.

  • low-protein flour
  • soft-wheat flour

Plain flour carries more protein than cake flour (around 10 to 12% vs 7 to 9%), giving a sturdier crumb. They are close in weight (140 g vs 130 g per cup); for a quick stand-in when out of cake flour, sift 1 cup of plain flour with 2 tablespoons removed and replaced with cornstarch. See plain flour in US cups.

Bread flour sits at the high end of protein (around 12 to 14%) while cake flour sits at the low end (7 to 9%), so they produce opposite textures. They differ by cup (150 g vs 130 g); they are not a straight swap, but blending half cake and half bread flour gives roughly the protein of plain flour. See bread flour in US cups.

Self-raising flour is plain flour pre-mixed with baking powder, so it has more protein than cake flour (around 10 to 12% vs 7 to 9%) and a slightly heavier cup (140 g vs 130 g). They are not a swap; cake flour gives a tender crumb, self-raising flour supplies its own lift. See self raising flour in US cups.
