  • Cup sizes are not standard worldwide, so the same cup of an ingredient can weigh more or less depending on the country. What is a cup measurement →
  • A teaspoon here is the 5 ml standard, the same in the UK, Europe, and Australia. A US teaspoon is fractionally smaller at about 4.9 ml. When teaspoon size matters →

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 120 grams or 4.23 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.

  • soft flour
  • 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 (125 g vs 120 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 our Plain Flour converter.

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 (130 g vs 120 g); they are not a straight swap, but blending half cake and half bread flour gives roughly the protein of plain flour. See our Bread Flour converter.
