Cake Flour

2 min | 2 min prep

2 cups

• 1 3/4 cups all-purpose flour
• 1/4 cup cornstarch

1. To make two cups of cake-and-pastry flour (cake flour), combine 1 3/4 cups all-purpose flour with 1/4 cup cornstarch; proceed with your recipe.
2. The easiest way to do this substitution is to put 2 tbsp of cornstarch in the bottom of a 1-cup measuring cup, then fill the cup as usual with all-purpose flour and level top. Repeat process to get your two cups.
3. If you only need 1/2 cup of cake flour, put 1 tbsp cornstarch in bottom of 1/2 cup measuring cup, then fill and level as above.

Cake flour, the lowest protein flour, has undergone a special bleaching process (distinct from the process used for other white flours) that increases the flour's ability to hold water and sugar. This means that when you're making baked goods with a high ratio of sugar to flour, the flour will be better able to hold its rise and will be less liable to collapse.
