What is Cake Flour made of?

Cake flour is made from soft winter wheat that is finely milled. It contains about 8% protein (as opposed to the 10-12% protein content in all-purpose flour.)

What is the difference between all purpose flour and cake flour?

The main difference between cake flour vs all purpose flour is the amount of protein. Cake flour contains less protein than all-purpose flour. Due to the lower protein content, it creates less gluten than all purpose flour.  It’s also finer and softer than all purpose flour.

Cake flour is preferred in many recipes because it creates cakes that are light and tender.

How to make cake flour

  • First, measure 3/4 cup + 2 tablespoons of all purpose flour. Add this to a bowl.
  • Next, measure 2 tablespoons cornstarch. Add it to the bowl with the flour.
  • Use a mesh sieve to sift the flour into another bowl. Sift one to two more times to aerate. Sifting ensures that the two ingredients are well combined and adds air to the mixture to create a light and velvety texture.

Can you use plain flour instead of cake flour?

Plain flour and cake flour are not the same. Generally, you do not want to substitute plain all purpose flour for cake flour. If you use plain all purpose flour instead of cake flour, you will need to add the cornstarch as specified in this cake flour recipe to achieve a similar result as cake flour.

Cake flour works best to create light and fluffy cakes, cupcakes and other baked goods. For example, we use cake flour in these strawberry cupcakes and vanilla cupcakes to ensure a light and fluffy texture. We also use a combination of cake flour and all purpose flour in these apple pie cupcakes to create a lighter cupcake.

Ingredients

  • 14 tablespoons all-purpose flour (3/4 cup + 2 tablespoons) (109g)
  • 2 tablespoons cornstarch (16g)

Instructions

  1. Add all purpose flour and cornstarch to a bowl. Sift the flour into another mixing bowl. Sift another 1 to 2 times. Sifting aerates the flour and ensures the mixture is fully combined.

Notes

  • We use a mesh sieve to sift the flour.
  • Sifting introduces air into the mixture. Therefore, this recipe may produce more than one cup of cake flour. If a recipe calls for 1 cup of cake flour, you will need to measure 1 cup from the mixture. 
  • Do not use cornmeal in this recipe. It is NOT the same as cornstarch. In some countries, like the UK, cornstarch is called corn flour.
