Did you know you can make Homemade Cake Flour Substitute by simply mixing together all-purpose flour and cornstarch?  Lots of cake recipes call for cake flour and it’s one staple that you might not always have on hand.  Use these tips for making it yourself at home.

If you’re not a frequent baker, you may not keep cake flour on hand.  Therefore, when you come across a cake recipe that you really want to make, and it calls for cake flour, what do you do?  Disregard the recipe and move on to another one?  Use all-purpose flour?  Use bread flour?  I’m here to tell you that you don’t have to consider any of these options. You can make your own cake flour substitute, and by the way, you should never substitute all-purpose flour for cake flour.


Cake Flour gets milled into a very fine consistency and contains only about 7 to 9 percent protein.  The lower the protein content, the less gluten, and the less gluten means a softer and fluffier texture.

All-Purpose Flour doesn’t get milled as much as cake flour and it also has a higher protein content of 9 to 11 percent which makes it form more gluten, thus creating a less soft texture.

Bread Flour has a much higher protein content than both cake and all-purpose flour, 11 to 13 percent making it form more gluten and resulting in a chewier texture.  The more gluten, the more stretch, and elasticity.

The key to making homemade cake flour substitute is in the SIFTING!

Sifting produces a softer flour and it also aerates the flour, giving it a softer consistency.  Notice the difference in the two pictures above.  The one on the left has not been sifted and the one on the right has been sifted twice.


You should use cake flour when you want a cake to have a soft and fluffy texture, such as a basic yellow, lemon, or vanilla cake.  I used it here in my Lemon Chiffon Layer Cake.


Anytime you make cakes that are extra moist with wet ingredients such as fresh fruit cakes or pound cakes that are meant to be dense and heavy you should not use cake flour.  These cakes need a more sturdy flour such as all-purpose.  You also wouldn’t want to use cake flour in bread recipes.  Bread needs a heavy flour such as bread flour.

Now go bake something yummy!
