Notes

Yield: The recipe makes a 2-cup serving. If you’d like to have more, you can double or triple the ingredients.
  • Make sure your cornstarch is fresh.
  • Use the spoon-and-level method when measuring baking ingredients. This ensures you get the right ratio, although using a kitchen scale will give you the most accurate results.
  • Be sure to mix the ingredients well and sift the mixture before storing.
Storage: Store homemade cake flour in an airtight container at room temperature for up to 1 year or in the refrigerator or freezer indefinitely.
