What is cake flour?

Cake flour is a finely milled, low-protein flour specifically designed for baking delicate, tender cakes and pastries. With a protein content of around 7 to 9%, significantly lower than all purpose flour, it produces less gluten when mixed, resulting in a lighter, softer texture in baked goods. The finely ground particles of cake flour also absorb more liquid and sugar, enhancing the moistness and structure of cakes.

How does homemade cake flour work?

By combining all purpose flour and cornstarch together you can create cake flour. Why does it work? By removing some of the all purpose flour and adding a binding agent, such as cornstarch, we are lowing the gluten formation and therefore the protein content in the flour. And, it will act and work just as cake flour in recipes.

What is cake flour?

Cake flour is a very fine flour that is milled to have a protein content of 7% to 9%. The lower protein content in cake flour makes for less gluten formation, and this provides a fluffier and lighter baked good. Hence, why it is used all the time for cake. Because cake should be light and tender, cake flour is used to achieve this perfectly delicate crumb.

Do you need to make cakes with cake flour?

Most layer cakes call for cake flour to achieve that light and tender crumb. But, some cakes, depending on the other ingredients inside the cake, are best when made with all purpose flour. My Orange Carrot Ginger Cake for example, uses all purpose flour. This is because the cake is very moist with the addition of the carrots. So, it actually requires all purpose flour to hold it together. This is why you will typically see all purpose flour in cakes like carrot, zucchini, banana or others that use fruits and veggies. Using the right kind of flour that a recipe calls for is crucial to have success, as flour makes a big difference in the texture and structure of your final baked goods.

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

While cake flour typically has 7% to 9% protein, all purpose flour has 10% to 12% protein. So, all purpose flour has more gluten formation, because of the higher protein content. This is great for baked goods like brownies and cookies where you want that gluten formation to create a chewy baked good that holds together well. But, cakes need less gluten formation in order to develop that tender and light crumb.
