make your own cake flour

Does your grocery store have the nerve to inconsistently stock cake flour? Does it drive you crazy to see recipe after recipe that calls for it, and wonder what else you can use? Good news: Cake flour is really easy to make at home. Add two tablespoons of corn starch to each cup of regular flour and sift this mixture together twice. Measure your cups of flour from this mixture.

  1. This is brilliant! Thanks so much. I never buy cake flour because I so rarely make cakes that need it, but I’m sure the cakes I have made with all-purpose have suffered as a result. Thanks!

  2. I’m so glad you shared this! The last time I bought cake flour it was expensive and went stale before I used it all. I always have corn starch in the house so this is perfect!

    When adding the cornstarch, does adding the cornstarch make a cup or do you add 2 TBS cornstarch to 1 whole cup of flour? Thanks

    Jill — It makes more than a cup. You mix them together and measure from there.

    Marie — Pastry flour is not the same as all-purpose or cake flour, so I’m not entirely following.

  5. Hi Deb – I’ve used this “homemade” version several times over the years in my favorite banana bread when I didn’t have cake flour on hand, and it came out fine. However, I recently wanted to make a yellow cake recipe that called for cake flour, and having none, I tried this substitute. Disaster! The cake failed to rise, it was way too dense, crumb was terrible. I’ve made the same recipe in the past with true cake flour and it comes out perfectly. Not sure if it was the subsitution, or if there was some other culprit, but now I’m very hesitant to use anything but “real” cake flour. Am I the only one who has had this problem?

    Hello- while doing research i came upon many sites that say to take out 2 tbsp of flour for ever cup, and add in 2 tbsp of cornstarch. you, however, do it differently. i’m not sure which one to do. has any one tried both and has an opinion?

    Awesome. I hate having six bags of different flours sitting in my pantry! Plus I don’t make cake often enough to justify buying one more flour.

  9. I’d love to see an update about making your own cake flour. Does corn starch have an expiration date? Can you make your own self-rising cake flour?
    I love your site and follow you religiously. Thanks for all the tips and tricks you pass along.

    Like Bee, I would also appreciate some info on what to do with leftover ‘cake flour’. I am making your almond raspberry cake, which calls for 4 1/2 cups of cake flour. Clearly using your method for my own ‘cake flour’ will result in leftovers. How long can I store it? What is the best way to combine leftover cake flour with non cake flour going forward?
