  • 3/4 cup + 2 tablespoons (110 grams) all-purpose flour , spooned & leveled
  • 2 tablespoons (15 grams) cornstarch (or cornflour)


  • Place the flour and cornstarch in a mixing bowl and whisk until well combined. Sift the mixture together 4-5 times, then measure out the amount of cake flour called for in your recipe by spooning it into a measuring cup and leveling it off with the back of a knife.


To make this recipe easier, you can measure out 1 cup of all-purpose flour and remove two tablespoons.
Always make sure to measure the flour needed in your recipe after sifting it.
