Measuring 450g of Cake Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cake flour weighs 114g when measured spooned & leveled, 450 Grams (450g) translates to 3.95 US cups (3 ¾ cups + 3 tbsp + ½ tsp). By contrast, using the sifted measure (100g/cup — a 14g per-cup shift), 450g occupies 4 ½ cups (4.50 cups).
Without a kitchen scale, measure 3 ¾ cups + 3 tbsp + ½ tsp (63.16 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.
