Step 1

Start by measuring out 2 cups of all-purpose flour. Pour them into a mixing bowl.

Step 2

Remove 4 tablespoons of the all-purpose flour from the 2 cups you just poured. You can put these tablespoons back into your flour container or set aside for another use.

Step 3

For every 2 tablespoons of flour you removed, add 2 tablespoons of cornstarch. So, for this recipe, add 4 tablespoons of cornstarch to the bowl.

Step 4

Use a whisk or a fork to mix the all-purpose flour and cornstarch together until they're really well combined. You want the cornstarch to be evenly distributed throughout the flour.

Step 5

For an extra fine texture, sift the mixture once or twice. This will ensure that the two ingredients are perfectly mixed and that your homemade cake flour is lump-free.
