If you’ve ever been in the middle of a recipe and wondered, “Is all purpose flour the same as plain flour?”, you’re not alone! This question is common for both beginner and seasoned bakers. While these two types of flour are often used interchangeably, there are a few subtle differences depending on where you live. In this blog post, I’ll explain everything you need to know about all purpose flour vs plain flour, their uses, and which one is right for your baking needs.

I remember when I first started baking, I assumed all flour was the same, but as a food content creator and recipe developer, I quickly learned the importance of choosing the right flour for different recipes. Flour is more than just a basic ingredient—it’s the foundation for the perfect texture, rise, and structure of your baked goods. Whether you’re making a pie crust, bread, or cake, using the right flour can make all the difference!

What Is the Difference Between All Purpose Flour and Plain Flour?

Is all purpose flour the same as plain flour? The short answer is yes—for the most part! The terms all purpose flour and plain flour are often used interchangeably, but the difference lies primarily in geography. In the United States and Canada, “all purpose flour” is the term commonly used, while in the UK, Australia, and some other countries, “plain flour” is the equivalent.

Both flours are made from a blend of soft wheat and hard wheat, resulting in a moderate protein content of around 10-12%. This balance makes them versatile and perfect for a variety of baked goods, from cakes and cookies to bread and pastry dough. So whether your recipe calls for all purpose flour or plain flour, you can confidently use either with similar results.

Flour Differences: Protein Content and Baking Purposes

One of the key differences between various types of flour is the protein content, which directly affects the gluten formation in your dough. Gluten is responsible for the elasticity and texture of baked goods. Here’s a quick breakdown:

Self-Rising Flour: A blend of plain flour or all purpose flour mixed with baking powder and a pinch of salt. It’s commonly used in recipes for biscuits, pancakes, and scones. If you’ve ever wondered if self rising flour is the same as all purpose, the answer is no—self-rising includes a leavening agent.

All Purpose/Plain Flour: Around 10-12% protein, making it suitable for a wide range of recipes. It strikes the perfect balance for both tender cakes and strong doughs.

Bread Flour: Contains a higher protein content (12-14%), which creates more gluten. This gives bread its chewy texture and strong structure. It’s ideal for recipes like bread and pizza dough.

Cake Flour: Lower protein content (6-8%), resulting in less gluten formation. Cake flour is perfect for delicate baked goods like cakes, pastries, and light sponge cakes. Cake flour in Australia is also a popular choice for fluffy desserts.

Pastry Flour: Falls between all purpose and cake flour with a protein content of around 8-9%. It’s great for making light and tender pastries, tarts, and pie crusts. If you’re looking for pastry flour in Australia, this is often used for pie crust and tart recipes.

How to Choose the Right Flour for Your Recipes

Choosing the right flour depends on the texture and outcome you’re aiming for in your baked goods. Here are a few tips for choosing the best flour for specific recipes:

Pizza Dough: Use bread flour if you want a chewy, stretchy crust with a bit more bite.

Bread: Go with bread flour for a higher rise and chewy texture.

Cakes: Use cake flour for a soft, tender crumb, or opt for all purpose flour if you prefer a slightly denser cake.

Pastry: Pastry flour offers the perfect balance for flaky and light pie crusts.

Cookies: All purpose flour or plain flour works best for most cookie recipes, as it gives just the right amount of chew without making the dough too tough.

Whole Wheat Flour vs All Purpose Flour

When it comes to health-conscious baking, whole wheat flour is often compared to all purpose or plain flour. Whole wheat flour is made from the entire wheat kernel, including the bran and germ, which gives it a slightly denser texture and higher fiber content. It also has more nutrients but results in heavier baked goods. All purpose flour or plain flour, on the other hand, is more refined, offering a lighter texture, which is why it’s the go-to for everyday baking.

If you’re looking to substitute whole wheat flour in a recipe that calls for all purpose, consider mixing half whole wheat with half all purpose to maintain a balance between health benefits and texture.

Common Questions About Flour

Is Plain Flour the Same as All Purpose Flour?

Yes! Plain flour and all purpose flour are essentially the same type of flour, especially when we talk about their use in baking. The main difference is the term—plain flour is used in the UK and Australia, while all purpose is common in the US and Canada.

Can I Substitute Bread Flour for All Purpose?

Yes, you can substitute bread flour for all purpose flour or plain flour, but keep in mind that the higher protein content in bread flour will create more gluten, giving you a chewier texture, which may not be ideal for cakes or delicate pastries.

What About Cake Flour? Is It Necessary?

Cake flour has a much lower protein content and is typically used for light and fluffy cakes. If you’re making a delicate sponge or chiffon cake, cake flour will give you the softest crumb. However, if you don’t have cake flour on hand, you can make a substitute by mixing all purpose flour with cornstarch to lower the protein.

Conclusion

In the world of baking, understanding flour differences can take your recipes to the next level. Whether you’re using all purpose flour, plain flour, or any other type of flour, choosing the right one can elevate the texture, flavor, and overall success of your baked goods.
