Ready In:
5-6 Cups




  • Measure out the amount needed for your recipe. I always measure out 6 cups of all purpose flour.
  • For every 1 cup of flour remove 2 Tbsp of flour.
  • Now add 2 Tbsp of Cornstarch for every 1 cup of flour. (replacing the tablespoons of flour taken out).
  • Sift 5-6 times and it's ready-to-use cake flour.
  • *To sift flour without a sifter just use a strainer by filling it with flour and tapping against the palm of your hand over a bowl.
  • (left-over flour can go back in the bag).
  • Always measure the flour that is needed after its sifted.

  1. I was trying to make cake flour, but i only replace 1T of cornstarch for the 1T of flour. Can this be fixed?
  2. I was supposed to replace 2 tablespoon of cornstarch for 2 tablespoon of flour. I forgot and only took out 1 T of flour, and replace 1T of cornstarch. I was trying to make my own cake flour. Can this mistake be resolved??

  1. My new mantra - I will never ever, never ever, purchase cake flour again! This worked wonderfully in a dark chocolate cake I made for a friend's birthday. I turned the cake into cupcakes and they were so light and fluffy and I truly feel it is due to the freshness of the cake flour. I had no idea but now that I know I'll never purchase it again. Thanks for sharing such a wonderful recipe that will help save me time and money in my kitchen! Made for I Recommend Tag game.
  2. Excellent cake flour sub-- though for ultimate laziness since I don't feel like getting my strainer dirty...I just put the cornstarch and flour (spooning it into the measuring cup-- as putting the cup into the flour bag just packs it in and makes it dense; gently spoon it out!) into a bowl and stirred with a fork to disperse the cornstarch, and it worked just perfect. If you're allergic to corn, potato starch and arrowroot powder also make good "softeners".
  3. Great money saving recipe. Thank you! I never want to buy cake flour because it's so expensive. I end up avoiding recipes that call for it. Now I use this recipe and just go for it when the recipe call for cake flour.
