Measuring 16 oz (1 lb) of Cake Flour in the Kitchen

Because 1 US Customary Cup (236.6 mL) of cake flour weighs 114g when measured spooned & leveled, 16 Ounces (453.6g) translates to 3.98 US cups (3 ¾ cups + 3 tbsp + 2 tsp). By contrast, using the sifted measure (100g/cup — a 14g per-cup shift), 16 oz occupies 4 ½ cups + 1 ¾ tsp (4.54 cups).

Without a kitchen scale, measure 3 ¾ cups + 3 tbsp + 2 tsp (63.66 tablespoons total) using spooned & leveled technique. Cake flour is milled extra fine and clumps easily in humidity; sift or whisk thoroughly before spooning into a measuring cup.
