Measuring 150g of Cake Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cake flour weighs 114g when measured spooned & leveled, 150 Grams (150g) translates to 1.32 US cups (1 ¼ cups + 1 tbsp + ¼ tsp). By contrast, using the sifted measure (100g/cup — a 14g per-cup shift), 150g occupies 1 ½ cups (1.50 cups).
Without a kitchen scale, measure 1 ¼ cups + 1 tbsp + ¼ tsp (21.05 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.
