Making a cake but don’t have any cake flour on hand? Use your all-purpose flour to make this cake flour substitute and save yourself a trip to the grocery store.
Measure out 1 cup of flour. Remove 2 tablespoons of the flour, returning it to your container for another use.
Add 2 tablespoons of cornstarch to the flour. Whisk together to combine, then sift the mixture at least 2-3 times to mimic the airy texture of cake flour.
