Homemade Cake Flour Recipe

When I got ready to bake up Madeline’s Birthday Cake Cupcakes last week for our family party night, I noticed that I was out of cake flour. I didn’t want to head out for another errand just to pick up a box of flour after spending the morning at various craft and party stores picking up the remaining items on my party list.

I was also out of buttermilk, but I already knew a good homemade buttermilk substitute. A quick message to my friend Shaina on Skype was returned with the answer I needed. “Okie dokie, then,” I said and proceeded to bake up some scrumptious cupcakes for my birthday girl using this easy DIY cake flour substitute. I wouldn’t use this all the time, but it is nice when you’re in a pinch.

Since I didn’t know about this handy substitution, I am guessing that a few of you probably did not know about it either. Thanks again, Shaina, for sharing this!

What is Cake Flour?

Unless you’re an avid baker like me, you might be looking for a cake flour substitute because you have no clue what it even is. In a nutshell, cake flour is a finely milled flour that contains less protein. It’s typically blanched and is most often used in cakes that need to be light and airy (think: angel food cake).

Cake Flour vs All-Purpose Flour

The main difference between cake flour and all-purpose flour is the protein content. According to The Kitchn, cake flour contains around 8% protein, and all-purpose has a little more than that.

Why does the protein content matter? Because the proteins become gluten when the flour is added to cake batter. The less gluten in the flour, the airier your cake will be.

What’s in Homemade Cake Flour?

To make a DIY cake flour substitute, you’ll need all-purpose flour and cornstarch. Seriously, that’s it! Yes, the all-purpose flour isn’t as finely milled as store-bought cake flour, but in a pinch this combo will work.

How to Make Cake Flour

To make a cup of homemade cake flour, add 2 tablespoons of cornstarch to a 1-cup measuring cup. Fill the remaining space with all-purpose flour. Pour mixture into a small bowl and whisk to combine. Proceed with the recipe as instructed.

I’ve given instructions on how to scale this basic recipe up as needed. If you need to make a cake flour substitute and aren’t sure what ratios to use, please leave me a comment and I’ll do my best to respond ASAP!

Can I Make Homemade Cake Flour in Bulk?

Yes, you can make a lot of this DIY cake flour substitute and store it in your pantry to have on hand at all times. Just note that you’ll need to sift the cake flour substitute before adding it to any recipe since you won’t be measuring out the cornstarch each time.

Is There a Cornstarch Substitute I Can Use?

Unfortunately, no. If you have a corn allergy or don’t have any cornstarch on hand, you can’t make this homemade cake flour.

Ways to Use Cake Flour

There are any number of cake flour uses to try, but a few of my favorite things to make with this special kind of flour are:

Are you drooling yet? There are so many ways to use cake flour. Play around with using homemade cake flour in your favorite baked goods and see if you can taste the difference. The added cornstarch makes cookies extra soft and chewy, and cakes turn out fluffier and better somehow!
