A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Spoon the flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20–30% more.
Sift cake flour if the recipe asks for "sifted"; a cup of sifted cake flour is lighter, about 100 g.
Also called: soft flour.
Weights are for a level US cup (236.6 ml) and level spoons, from King Arthur Baking's ingredient weight chart. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of cake flour weighs about 120 g (4.2 oz). A 250 ml metric cup weighs about 127 g.
1 level tablespoon of cake flour is about 7.5 g, and 1 teaspoon is about 2.5 g.
100 g of cake flour is about 0.83 cups, or 13.3 tablespoons.
A cup measures volume, not weight. Cake Flour is full of air between the particles, so a cup weighs much less than a cup of water (120 g vs 237 g).
