What is Cake Flour?

It’s a low protein flour that’s typically used in baking and especially cakes to give it that wonderfully firm but soft texture. This is typically the flour that is used in fancy bakeries.

Cake Flour is Better Homemade!

My Aunt (who is a fabulous baker, by the way!) taught me how to make DIY cake flour with all-purpose flour at home because it’s a little expensive to buy at stores.

As an experiment, I made my favorite vanilla cupcakes with store-bought and homemade cake flour and they BOTH looked the same and tasted the SAME!

Only 2 Cake Flour Ingredients!

  1. All purpose-flour
  2. Cornstarch

The key is SIFTING! You need to sift these 2 ingredients multiple times because it allows the cornstarch and flour to mix together thoroughly.

Cake Flour vs All-Purpose Flour

The main difference is the protein content. Cake flour has a lower protein content than all-purpose flour and that results in a light, airy and fluffy cake texture.
