Measuring 4 oz of Cake Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cake flour weighs 114g when measured spooned & leveled, 4 Ounces (113.4g) translates to 0.99 US cups (1 cup). By contrast, using the sifted measure (100g/cup — a 14g per-cup shift), 4 oz occupies 1 ⅛ cups (1.13 cups).
Without a kitchen scale, measure 1 cup (15.92 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.
