Ingredient questions

Cake flour FAQ.

How many grams are in a cup of cake flour?

King Arthur Baking lists 120g for 1 US cup of unbleached cake flour.

Is cake flour the same as all-purpose flour by weight?

This site uses 120g per cup for both references because that is what the King Arthur chart lists for the named entries. Their baking performance is still different because protein and milling differ.

Should cake flour be sifted before measuring?

Follow the recipe's stated method. If it does not say, spoon it into the cup and level it rather than scooping and compressing it.
