Measuring Cake Flour Accurately
Why weight matters: 1 1/2 cups of cake flour can weigh anywhere from 128g to 180g depending on how you measure it. The USDA standard is 150g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About cake flour density: Cake flour is the lightest of all wheat flours. Very finely milled with low protein (7-9%). 1 cup = 100g (sifted). Always sift cake flour before measuring. Used for tender cakes, delicate pastries.
About 1½ Cups as a Measurement
1 1/2 cups = 24 tablespoons = 360ml. This is the standard flour amount for a dozen standard-size cookies or a single-layer 8-inch cake. It bridges the gap between single-cup and double-cup recipe scales.
One and a half cups appears most often in cookie dough recipes (flour), quick bread recipes (oats or mix-ins), and pasta sauce recipes (liquid ingredients). It equals 360ml or 12 fluid ounces.
