Cake flour Substitutes — Tested Swaps & Ratios

Cake flour substitutes^A

Tested swaps for cake flour, with ratios and sources.

1 cup cake flour^A = ⅞ cup all-purpose flour^A (14 tbsp) + 2 tbsp cornstarch, sifted together (King Arthur Baking / America's Test Kitchen)
Cornstarch dilutes the AP flour's protein to mimic cake flour's tender crumb. Sift the blend two or three times so the cornstarch distributes evenly.
