Learn how to make your own cake flour with just two simple ingredients. This easy substitute is perfect for cakes, cupcakes, and so much more!
Let’s be honest, there’s nothing more frustrating than realizing you’re missing an ingredient in the middle of baking. I recently shared an easy homemade buttermilk substitute with you, so today I want to share another substitute – homemade cake flour.
What exactly is cake flour? It’s made from soft wheat and is much finer than all-purpose flour. The main difference between the two is the protein content, cake flour usually has about 7-9% and all-purpose flour can have anywhere from 10-12%.
The lower protein content means that it forms less gluten as you’re mixing everything together, which results in a softer and lighter texture. This makes it perfect for recipes where you want a lighter texture, like with cakes and cupcakes.
So today, I’m showing you how to make your own with just two ingredients. And I bet you probably have both ingredients on hand right now!
How To Make Cake Flour
To make your own cake flour substitute you’ll need two ingredients: all-purpose flour and cornstarch. If you live outside of the US, then you’ll probably need to look for cornflour which is the same thing as cornstarch.
Also, this recipe and tutorial will make about 1 cup. If you need more or less, just scale the recipe up or down as needed.
To start, you’ll measure out one cup of all-purpose flour. One important thing to remember for this step is that you need to spoon your all-purpose flour into the measuring cup then level it off with the back of a knife.
If you scoop your flour from the container, it can become packed inside the cup and you can end up with WAY too much flour.
Then, remove two tablespoons of the flour and add it back to your flour bag or container. Next, replace the two tablespoons of flour with two tablespoons of cornstarch (or cornflour).
Why cornstarch? The cornstarch inhibits some of the gluten formation, which results in a softer baked good.
Once you’ve added the cornstarch, whisk it into the flour until well combined and sift the mixture 4-5 times. This will help aerate the flour and incorporate the two together really well.
Then, measure out the amount of cake flour needed in your recipe by spooning the sifted flour into your measuring cup and leveling it off with the back of a knife.
Different Ways to Use It
Here are a few ways that you can use this substitute. On Thursday, I’ll be sharing an easy homemade angel food cake recipe that works great with this recipe too!
