Self-raising flour is a versatile kitchen staple, essential for various baking endeavors. However, there might be occasions when you find yourself out of self-raising flour but have plain flour at hand. Fear not, for with a simple kitchen hack, you can easily transform plain flour into self-raising flour. In this article, we’ll explore the step-by-step process of creating this indispensable ingredient.

    Ingredients Needed:

    1. Plain Flour
    2. Baking Powder

    Steps to Make Self-Raising Flour from Plain Flour:

    Gather the Ingredients:

    Before you begin, make sure you have plain flour and baking powder on hand. These are the only ingredients you’ll need for this kitchen transformation.

    Calculate the Ratio:

    The key to converting plain flour into self-raising flour lies in the ratio. For every cup (120g) of plain flour, you’ll need to add 2 teaspoons of baking powder. This ratio ensures that the flour is properly leavened, resulting in light and fluffy baked goods.

    Sift the Ingredients:

    Sifting is an important step to ensure even distribution of the baking powder throughout the flour. Place the plain flour in a large mixing bowl and add the calculated amount of baking powder.

    Mix Thoroughly:

    Use a whisk or a fork to combine the plain flour and baking powder thoroughly. Continue mixing until the baking powder is evenly distributed throughout the flour.

    Store for Future Use:

    If you find yourself needing self-raising flour on a regular basis, consider preparing a larger batch and storing it in an airtight container. This way, you’ll have a convenient supply at your disposal.

    Tips and Considerations:

    Check the Expiry Date of Baking Powder:

    It’s important to ensure that your baking powder is fresh and active. Expired or inactive baking powder will not yield the desired leavening effect.

    Adjust for Larger Quantities:

    If you need more than a cup of self-raising flour, simply adjust the ratio accordingly. For instance, if you require 2 cups of self-raising flour, use 240g of plain flour and 4 teaspoons of baking powder.

    Use a Fine-Mesh Sifter:

    A fine-mesh sifter or sieve can help ensure that the baking powder is evenly distributed. This step is crucial for achieving consistent results in your baked goods.

    Incorporate Other Flavors:

    If you want to add a touch of flavor to your self-raising flour, consider incorporating ingredients like cocoa powder, cinnamon, or even grated cheese, depending on the recipe you’re preparing.

    Test the Freshness of Baking Powder:

    If you’re unsure about the freshness of your baking powder, perform a quick test. Add a small amount to a cup of hot water. If it bubbles vigorously, it’s still active and can be used to make self-raising flour.


    With just two simple ingredients and a few easy steps, you can transform plain flour into self-raising flour right in your own kitchen. This kitchen hack is a game-changer for any home baker facing a shortage of self-raising flour. By understanding the ratio and following the steps outlined in this article, you’ll be well-equipped to create light, fluffy, and perfectly leavened baked goods. So the next time your recipe calls for self-raising flour, you’ll have the confidence to whip up a batch from plain flour with ease. Happy baking!
