Measuring 16 oz (1 lb) of Gluten-Free 1-to-1 Baking Flour in the Kitchen

Because 1 US Customary Cup (236.6 mL) of gluten-free 1-to-1 baking flour weighs 148g when measured spooned & leveled, 16 Ounces (453.6g) translates to 3.06 US cups (3 cups + 1 tbsp). By contrast, using the dip scooped measure (160g/cup — a 12g per-cup shift), 16 oz occupies 2 ¾ cups + 1 tbsp + 1 tsp (2.83 cups).

Without a kitchen scale, measure 3 cups + 1 tbsp (49.04 tablespoons total) using spooned & leveled technique. Formulated with rice flour, starches, and xanthan gum. Spoon into cup and sweep level without packing down.
