  • Whisk together the flour and cornstarch in a medium bowl.
  • Sift the mixture 3 times then use as needed in recipes calling for cake flour.


  • You can make this recipe in whole cup volumes. The rule is to replace 2 tablespoons of every cup of all-purpose flour with 2 tablespoons of cornstarch.
  • Sifting is essential and I highly recommend whisking the ingredients together before sifting as well.
