About ounces Cake Flour (ounces)
Ounces of Cake Flour. Measured by US avoirdupois ounce (= 28.349523125 g exactly per NIST SP 811 — distinct from fluid ounce which is a volume unit). Mass-ounce measurement is preferred in US butcher/bakery/professional contexts where precision matters but the recipe uses imperial customary units. Common US baking ingredient packages list both ounces (mass) + grams: a stick of butter = 4 oz = 113 g; a 'pound' of flour = 16 oz = 454 g. CRITICAL: do NOT confuse with the troy ounce (~31.1 g — used only for precious metals) or the fluid ounce (volume unit = 29.57 mL). Cake flour is low-protein wheat flour (6-8% per Swans Down, Softasilk, Bob's Red Mill specs) made from soft red or soft white winter wheat. The low protein content produces minimal gluten development, yielding the tender, fine-crumbed texture required for angel food cakes, chiffon cakes, sponge cakes, devil's food cakes, and the highest-rise box cake mixes. Most US cake flours are bleached with chlorine gas, which oxidizes proteins + starches to further weaken gluten and increase starch absorption (DIY substitute: 1 cup AP flour - 2 tablespoons + 2 tablespoons cornstarch, sifted three times, gives approximate cake-flour behavior). Density ~0.480 g/mL (1 cup = 113-120 g per Swans Down standard). European 'Type 405 fine' or Italian '00 superfine' is the closest equivalent. Brand options: Softasilk (Pillsbury), Swans Down (Reily), King Arthur Cake Flour, Bob's Red Mill Super-Fine. Density: 0.480 g/mL (used to convert volume measurements to mass).
About cups Cake Flour (cups)
Cups of Cake Flour. Measured by US cup (= 240 mL = 16 US tablespoons = 48 US teaspoons per FDA 21 CFR 101.9). The cup is the dominant US baking + cooking volume unit, but actual density varies significantly by how the ingredient is packed (scooped vs spooned-and-leveled — a 1-cup scoop of flour can range from 110 g to 150+ g depending on technique, which is why precise bakers use mass measurement in grams). Always level with a flat edge (the back of a knife) for accurate volumetric measurement.
