Out of cake flour? The cake flour substitute is 2 tablespoons of cornstarch swapped into every cup of all-purpose flour — chart and calculator for any amount. Thickening a sauce rather than baking? The cornstarch to flour thickener conversion swaps between them: cornstarch has twice the thickening power, so use half as much.

Frequently asked questions

How many grams is 1 cup of flour?

One cup of all-purpose flour weighs about 120 g. Bread flour and cake flour are also 120 g per cup, while whole wheat and self-rising flour are 113 g. Starches differ more: cornstarch is 112 g and coconut flour 128 g.

Do all flours weigh the same per cup?

No. Most wheat flours are close to 120 g per cup, but density varies a lot: almond flour is only 96 g and oat flour 92 g, while semolina is 163 g. Always convert by the specific flour rather than using one ratio.

How do you measure a cup of flour accurately?

Spoon the flour into the cup and level it off with a knife — don't dip the cup and scoop, which packs the flour and can add 20% more weight. For real accuracy, weigh it in grams.

Is a cup of bread flour the same as all-purpose flour?

By weight, yes — both are about 120 g per cup. They differ in protein content, not density, so you can swap the weights directly.
