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.
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:
Cake flour’s soft, tender texture directly translates into your baked good.
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
- 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!)
- Add cornstarch to the 14 Tablespoons of flour.
- 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.
- 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.
- 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
- 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.
- 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.
