Cake Flour Substitute

You only need two common ingredients– all-purpose flour and cornstarch– to make a homemade cake flour substitute. Sifting them together is key. Use this mixture whenever a recipe calls for cake flour.

As my baking experience grows, I use cake flour more and more in my baking. There’s no denying that cake flour produces the softest, most tender cakes and cupcakes. I try to keep my kitchen stocked with this crucial ingredient, but sometimes I quickly run out when I’m recipe testing. So in a pinch, I make this super easy cake flour substitute.

Let’s back up for a minute though.

What is Cake Flour?

Cake flour is a low protein flour that’s milled into a fine consistency. It contains about 7-9% protein, while all-purpose flour, a harder flour, has anywhere between 10-12%. What does this mean for baking? You see, protein content is directly related to gluten formation. Cake flour’s lower protein means less gluten is formed as you mix the batter together. Less gluten formation equates to a softer, fluffier texture.

Bread flour has a high protein content, which means more gluten forms during the mixing process. Super basic breakdown:

  1. Cake flour = low protein = less gluten = softest texture = great for vanilla cake
  2. All-purpose flour = medium protein = moderate gluten = suitable for anything
  3. Bread flour = high protein = more gluten formation = hardest texture = great for bread

What Does That Mean for Baking?

Cake flour’s soft, tender texture directly translates into your baked good.

However, some recipes simply can’t withstand fine cake flour. Chocolate cake, for example, already has cocoa powder— which is a VERY fine dry ingredient. The combination of cake flour and cocoa powder usually results in a flimsy cake. Additionally, carrot cake and banana cake contain additional wet ingredients (the fruits or veggies), so cake flour isn’t really ideal. You need a stronger flour like all-purpose flour.

I stick to cake flour when making vanilla cake, white cake, pineapple upside-down cake, red velvet cake, and other cakes where a fluffy texture is favorable. I’ve been successful substituting cake flour for all-purpose flour to create a softer funfetti cake. Make a 1:1 substitution with no other changes to the recipe.

How to Make a Homemade Cake Flour Substitute

Step 1: Measure 1 cup all-purpose flour. Remove 2 Tablespoons.

Step 2: Measure 2 Tablespoons cornstarch. Add to the flour. Cornstarch contains less gluten than flour, so it’s a wonderful tenderizing ingredient to help make cake flour.

Step 3: Sift together TWICE. Basically, sift into a mixing bowl once. Then run it through the sifter one more time. Sifting not only mixes the two ingredients together appropriately, it aerates the mixture so the consistency is similar to real cake flour.

Step 4: Measure 1 cup from this mixture. You’ll have about 1 cup anyway, but sometimes sifting can produce more volume since it’s adding air.

If you’re purchasing cake flour, though, I’m happy to share my favorite brands. I love Swans Down and Softasilk. (Not working with either, just a genuine fan!) I use unbleached when I can find it, otherwise I just stick with bleached. Both brands provide quality results for a good price. You can find cake flour in the baking aisle next to the all-purpose flour.

Description

You only need two common ingredients– all-purpose flour and cornstarch– to make a homemade cake flour substitute. Sifting them together is key. Use this mixture whenever a recipe calls for cake flour.


Ingredients

  • 1 cup (125g; 16 Tablespoons) all-purpose flour (spoon & leveled)*
  • 2 Tablespoons (16g) cornstarch

Instructions

  1. Start with 1 cup all-purpose flour. Remove 2 Tablespoons (16g) so you have 14 Tablespoons total. (Use the 2 Tablespoons you removed another time. Just put it back in the flour bag/canister!)
  2. Add cornstarch to the 14 Tablespoons of flour.
  3. Sift together TWICE. Basically, sift into a mixing bowl. Then run it through the sifter one more time. Sifting not only mixes the two ingredients together appropriately, it aerates the mixture so the consistency is similar to real cake flour.
  4. Measure (spoon & level) 1 cup from this mixture. You’ll have about 1 cup anyway, but sometimes sifting can produce more volume since it’s adding air.
  5. Now you have 1 cup of cake flour that you can use in any recipes requiring cake flour. If the recipe requires more than 1 cup cake flour, you can do this process in bulk, but I find it’s better to make each cup of cake flour separately.

Notes

  1. Basically you need 14 Tablespoons (3/4 cup + 2 Tablespoons; 109g) of spoon & leveled all-purpose flour. Sometimes it’s easier to measure 1 cup (16 Tablespoons) then remove 2 Tablespoons than to individually measure 14 Tablespoons. Alternatively, you could measure 3/4 cup flour then add 2 Tablespoons.
  2. Cornstarch is extra fine and lowers the gluten formation in the all-purpose flour, similar to cake flour. In the UK, cornstarch is referred to as corn flour. Make sure you are not using cornmeal. They are completely different ingredients.

  1. Hi Sally What is the best cake flour to use? And can you buy it at a wholesale price in a large quantity

    1. Lexi @ Sally's Baking Addiction says:

      Hi Marie, we often use Softasilk or Swans Down cake flours. Feel free to buy in a large quantity if that option is available to you!

  2. Sandra Damron says:

    Can you use cake flour with pound cake?

    1. Trina @ Sally's Baking Addiction says:

      Hi Sandra! It definitely depends on the recipe, but we do use cake flour in our favorite cream cheese pound cake recipe.

  3. Hi Sally, I would like to try baking the famous Jacque Torres chocolate chip cookies, which call for cake and bread flours – neither of which I keep on hand. You given a substitute for the cake flour here but do you also have a workable bread flour substitute that uses all-purpose with additions?
    Thank you!

    1. Michelle @ Sally's Baking Addiction says:

      Hi Jeff, We haven’t tried it but some people do add vital wheat gluten to all purpose flour to get the same chewy texture as bread flour. You can also simply use all purpose flour in it’s place although the texture will not be quite as chewy. I hope this helps!

  4. I am making cookies that are calling for cake flour. What would cake flour do to the consistency of a cookie? For example, cutout sugar cookies or drop sugar cookies. I’ve never made cookies with cake flour, so I am curious about how a cake flour cookie would taste and what the texture of it would be. Thank you!

    1. Trina @ Sally's Baking Addiction says:

      Hi Casey! Cake flour would yield a lighter, more delicate texture.

  5. Claudia Di Mele says:

    Sally, I only buy skim milk. Can I use skim milk in this recipe?

    Everything I made from your recipes have been delicious…….

    1. Michelle @ Sally's Baking Addiction says:

      Hi Claudia, The cake flour substitute doesn’t use milk. Let us know if you meant this comment for another recipe and we’d be happy to help!

  6. Well…..cake flour…thought flour was flour…I do use unbleached flour for all my recipes. Plan to make a jelly roll/swiss roll cake and saw the recipe called for cake flour….Duly noted I will use cake flour in my first attempt.

    Look forward to letting you know how my first endeavor turns out.

    Happy Baking!
