    Cake Flour Substitute

    If you don’t have cake flour on hand, or live in a country where it’s banned (like here in New Zealand!), then this cake flour substitute is a great alternative. You can use it for most recipes that call for cake flour, and my cakes always come out softer with a more delicate crumb when I use this substitute 🙂

    What is cake flour?

    Cake flour is a special type of flour that’s used to make, well, cakes! It’s made from a soft wheat and has less protein than regular all-purpose flour. Cake flour has a protein content of around 6-8%, whereas all purpose flour has a protein content of around 10-12%. That makes cake flour perfect for making cakes and pastries that need to be super soft and tender.

    Why is cake flour banned in New Zealand?

    Cake flour is chlorinated, which basically means that is goes through a bleaching process which weakens the protein in the flour. It’s this bleaching process that makes it an illegal product here in New Zealand – who would have thought cake flour would be banned right?! I know I was first shocked to find this out.

    So what is so bad about the bleaching process? Well, it’s the chemicals that are used in the bleaching process which are deemed as harmful, hence it’s ban.

    DISCLAIMER: Please do not take this as me telling you not to use cake flour. Honestly, I haven’t done enough research in the area myself and it’s not something I actively avoid when I go overseas, so that’s completely up to you to decide 🙂

    What is a cake flour substitute?

    Now I am SO DETERMINED to share the softest, fluffiest cakes with you all, so I use a cake flour substitute in many of my cake recipes. This substitute consists of a mix of regular all purpose flour and cornstarch (hence why you’ll see cornstarch in a lot of my recipes, like my very popular vanilla cake and red velvet cake recipes!).

    To make this cake flour substitute it’s really easy.

    Place a cup of regular all purpose flour into a bowl and remove two tablespoons of it. Replace the two tablespoons with two tablespoons of cornstarch.

    • Agha

      Hi. Sorry if this sounds a bit confusing but how would you let’s say replace a particular cake flour in grams with ap flour & cornflour? Example, a recipe calls for 213 grams of cake flour so then I would substitute it with around 200 gms of ap flour and 25 gms of corn flour? 😄

      • Cakes by MK

        Heya! Not confusing at all 🙂 so I would basically substitute an 1/8th of the original quantity with cornflour. So in your case it would be about 26g of cornflour and the rest would be regular flour 🙂 hope that makes sense!
