Self-rising flour is a convenience product that combines all-purpose flour, baking powder, and salt in pre-measured ratios. The standard formula is 1 cup all-purpose flour, 1 1/2 teaspoons baking powder, and 1/4 teaspoon salt. This premixed flour is particularly popular in Southern American baking — biscuits, pancakes, and some cake recipes — as well as in British baking for scones, sponge cakes, and puddings. The idea is simple: fewer ingredients to measure out every time.
You might need a substitute for self-rising flour if you don't keep it on hand (it's a specialty item in some regions), if it has gone stale (the baking powder in it has a limited shelf life), or if your recipe only needs a small amount and you don't want to buy a whole bag. The good news is that making your own self-rising flour substitute is one of the simplest swaps in baking.
One important caution: when substituting self-rising flour, always check whether your recipe adds any additional baking powder or salt on top of the self-rising flour. If it does, you'll need to adjust those additions carefully to avoid over-leavening or over-salting the recipe. Recipes designed for self-rising flour typically don't call for extra baking powder or salt separately.
■Best Substitutes for Self-Rising Flour
These substitutes work in biscuits, pancakes, scones, quick breads, and other recipes that call for self-rising flour.
| Substitute | Flavor / Texture Match | Swap Ratio |
|---|---|---|
| All-Purpose Flour + Baking Powder + Salt | Identical — the standard DIY formula | 1 cup AP + 1½ tsp baking powder + ¼ tsp salt |
| Cake Flour + Baking Powder + Salt | Lighter, more tender crumb | 1 cup cake flour + 1½ tsp baking powder + ¼ tsp salt |
| Whole Wheat Flour + Baking Powder + Salt | Nuttier, denser, more nutritious | 1 cup WW flour + 1½ tsp baking powder + ¼ tsp salt |
| Whole Wheat Self-Rising Flour | Whole grain version — direct swap | 1:1 |
| Spelt Flour + Baking Powder + Salt | Mild, slightly sweet whole grain | 1 cup spelt + 1½ tsp baking powder + ¼ tsp salt |
| Gluten-Free AP Flour Blend + Baking Powder + Salt | Gluten-free option | 1 cup GF blend + 1½ tsp baking powder + ¼ tsp salt |
■How to Choose the Right Substitute
The simplest and most reliable substitute for self-rising flour is to make it yourself: combine 1 cup of all-purpose flour with 1 1/2 teaspoons of baking powder and 1/4 teaspoon of salt. Whisk them together thoroughly before using. This formula is essentially the industry standard and produces results that are indistinguishable from store-bought self-rising flour. Make only what your recipe calls for and use it immediately — don't store homemade self-rising flour unless you're making a large batch, as the baking powder can lose potency over time.
If you want a more nutritious substitute, whole wheat flour or spelt flour can be used in the same formula. Whole wheat self-rising flour is available commercially and can be swapped 1:1 for regular self-rising flour. Using whole wheat flour in the DIY formula produces denser, heartier baked goods with a nuttier flavor — this works beautifully in pancakes and some biscuits but may produce a heavier result in delicate cakes or scones.
For lighter, more tender results than standard self-rising flour produces — particularly for fine cakes — substitute cake flour in the DIY formula. Cake flour's lower protein content results in less gluten development and a more delicate crumb. This swap works especially well in sponge cakes, Victoria sandwiches, and other recipes where a very light texture is the goal. For gluten-free baking, use a commercial gluten-free all-purpose flour blend (which already contains xanthan gum or other binders) and add the baking powder and salt.
■Frequently Asked Questions
Why does self-rising flour go stale? The baking powder in self-rising flour loses its leavening power over time, especially if the flour has been exposed to moisture or heat. Baking powder is activated by both moisture and heat, so any ambient humidity can cause it to partially react while sitting on the shelf. Always check the expiration date on store-bought self-rising flour, and test the flour's leavening power before using by adding a teaspoon to hot water — it should bubble actively. If it doesn't, the baking powder has degraded and your baked goods won't rise properly.
Can I use self-rising flour instead of all-purpose flour in a recipe that calls for baking powder? In most cases, yes — but you need to omit the baking powder and salt that the recipe separately calls for, since they're already built into the self-rising flour. The standard formula assumes 1 1/2 teaspoons baking powder and 1/4 teaspoon salt per cup of all-purpose flour are already present. If your recipe calls for different amounts, adjust accordingly.
Is self-rising flour the same in the US and UK? The leavening levels are similar, but UK self-raising flour (note the different spelling) typically uses a slightly different formula and is made from softer (lower-protein) wheat than US self-rising flour. UK self-raising flour is closer to a blend of pastry flour and leavener, which is why British sponge cakes made with it are notably lighter. If you're following a British recipe with US self-rising flour, your results may be slightly denser — consider using the cake flour variation of the DIY formula to compensate.
Can I make self-rising flour with baking soda instead of baking powder? Baking soda alone won't work as a substitute for baking powder in this context because baking soda requires an acid to activate. If your recipe contains acidic ingredients (buttermilk, yogurt, vinegar, molasses, or lemon juice), you can use baking soda — use 1/2 teaspoon baking soda per cup of flour and ensure there's enough acid in the recipe to activate it. Without an acid, baking soda will produce a soapy, bitter taste in the finished product.
Does the type of salt matter in homemade self-rising flour? Most recipes assume table salt (fine-grained). If you're using kosher salt or sea salt (which have larger crystals and pack less densely into a measuring spoon), use slightly more — about 1/3 to 1/2 teaspoon per cup of flour. Diamond Crystal kosher salt in particular is much less salty by volume than table salt due to its hollow crystal structure, so you'd need to double the amount.
