Measuring 30g of Old-Fashioned Rolled Oats in the Kitchen
Because 1 US Customary Cup (236.6 mL) of old-fashioned rolled oats weighs 90g when measured dip and sweep, 30 Grams (30g) translates to 0.33 US cups (⅓ cup).
Without a kitchen scale, measure ⅓ cup (5.33 tablespoons total) using dip and sweep technique. Spoon rolled oats gently into a dry measuring cup until heaping, then sweep level with a straight edge. Shaking or tapping the cup settles the broad, flat oat flakes into trapped gaps, increasing cup weight to nearly 100 grams.
