Measuring 4 oz of Oat Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of oat flour weighs 92g when measured spooned & leveled, 4 Ounces (113.4g) translates to 1.23 US cups (1 cup + 3 tbsp + 2 ¼ tsp). By contrast, using the scooped from bag measure (104g/cup — a 12g per-cup shift), 4 oz occupies 1 cup + 1 tbsp + 1 ¼ tsp (1.09 cups).
Without a kitchen scale, measure 1 cup + 3 tbsp + 2 ¼ tsp (19.72 tablespoons total) using spooned & leveled technique. Spoon lightly and level. Oat flour is exceptionally light and fluffy; shaking the cup causes severe settling.
