To make self-rising flour, whisk 1 cup all-purpose flour with 1½ tsp baking powder and ¼ tsp fine salt; mix well and use or store airtight.
Short on self-rising flour? You can mix a fresh batch in minutes with pantry staples. The method is simple, the ratio is reliable, and the results match store-bought for most quick breads, biscuits, muffins, and tender cakes. Below you’ll find the core formula, easy scale-ups, and fixes for common hiccups.
How To Make Self Rising Flour At Home: Ratios That Work
The base formula is steady: one cup of all-purpose flour, one and a half teaspoons of baking powder, and a quarter teaspoon of fine salt. That blend mirrors what commercial bags contain, and it’s the reason many recipes call for self-rising flour by name. If you’re thinking, “how do you make self rising flour?” the short ratio above is the answer.
Quick Ratio Table (US Volume And Metric)
Use this table to scale up without math on the fly. Whisk dry ingredients for at least 30 seconds so the baking powder disperses evenly.
| Flour (Cup / g) | Baking Powder (tsp / g) | Fine Salt (tsp / g) |
|---|---|---|
| ½ cup / 60 g | ¾ tsp / ~3.5 g | ⅛ tsp / ~0.75 g |
| 1 cup / 120 g | 1½ tsp / ~7 g | ¼ tsp / ~1.5 g |
| 2 cups / 240 g | 3 tsp / ~14 g | ½ tsp / ~3 g |
| 3 cups / 360 g | 4½ tsp / ~21 g | ¾ tsp / ~4.5 g |
| 4 cups / 480 g | 6 tsp / ~28 g | 1 tsp / ~6 g |
| 5 cups / 600 g | 7½ tsp / ~35 g | 1¼ tsp / ~7.5 g |
| 6 cups / 720 g | 9 tsp / ~42 g | 1½ tsp / ~9 g |
Step-By-Step Method
- Measure the flour. Spoon all-purpose flour into the cup, then level with a straight edge. For best consistency, weigh it.
- Add the leavener. Sprinkle in baking powder. Level the spoon so you don’t pack extra by accident.
- Add salt. Use fine table or fine sea salt. Coarse grains don’t disperse as evenly.
- Whisk well. At least 30 seconds in a wide bowl. You’re aiming for even distribution.
- Use or store. If baking now, move straight to the recipe. If storing, seal in an airtight container away from heat and moisture.
How Do You Make Self Rising Flour? (Step-By-Step)
Let’s put that into practice with a small batch. In a medium bowl, combine 240 g (2 cups) of all-purpose flour, 3 teaspoons baking powder, and ½ teaspoon fine salt. Whisk until the mix looks uniform and no streaks remain. That’s it—ready for biscuits, skillet cornbread, soda bread, or a tender snack cake.
Many bakers ask, “how do you make self rising flour?” when a recipe lists it but only plain flour sits in the cupboard. This method gets you there fast without a trip to the store.
Why This Blend Works
Baking powder releases gas twice—once when it meets moisture and again in the oven. That two-stage lift helps you get a soft crumb without adding separate acids like buttermilk or vinegar. Salt adds a light savory note and strengthens the structure, which keeps the crumb from tasting flat.
When To Use It
- Quick breads and muffins: Even rise, tender bite.
- Biscuits and scones: Clean lift with flaky layers when the dough stays cold.
- Snack cakes: Good for light, single-bowl cakes where the recipe doesn’t include extra acid.
Regional Notes And Protein Levels
“Self-rising” in the US typically assumes all-purpose flour with moderate protein. In the UK and Australia, “self-raising” often starts with a slightly different base flour and a cup may weigh closer to 150 g. That’s why weighing your flour helps, especially when you bake from a recipe that originated in a different region.
Can You Use Cake Flour Or Whole Wheat?
Cake flour: Works for very tender cakes but can feel too delicate in biscuits. If you try it, mix gently and avoid extra liquid.
Whole wheat: Tasty in quick breads. Add a splash more liquid since bran draws water. Keep the same baking powder and salt per cup of flour.
Make-Ahead And Storage
Fresh is best, but a small jar on the shelf is handy for weeknight baking. Seal tightly, keep it cool and dry, and rotate small batches. If the blend sits for months, baking powder can lose punch. A quick test: stir ½ teaspoon of your mixed flour into warm water. Light bubbling means the leavening still has life.

Swaps, Tweaks, And Salt Choices
Salt Types
Use fine salt for accuracy. If you only have kosher salt, you’ll need a larger volume to match the same mass. When in doubt, weigh it. Many bakers prefer fine sea salt for a clean taste with easy dispersion.
Gluten-Free Version
Grab a cup-for-cup gluten-free blend that already contains a binder (xanthan gum or similar). Use the same ratio: 1 cup blend, 1½ teaspoons baking powder, ¼ teaspoon fine salt. Whisk well. Texture will vary by brand, so note your results and tweak liquid next time if the batter looks tight.
Low-Salt Or No-Salt Option
You can leave out the salt and add it directly to the recipe batter instead. This helps if you’re tracking sodium or baking something that includes salty mix-ins like cheese or cured meat.
Convert A Recipe That Calls For Self-Rising Flour
If a recipe lists self-rising flour but you’re using plain flour, add the ratio per cup of flour and omit any extra baking powder and salt listed in the recipe. Skipping that subtraction doubles the leavener and can lead to a quick rise and collapse or a bitter taste.
US To Metric Cheat Sheet
- 1 cup flour ≈ 120 g (US all-purpose)
- 1 teaspoon baking powder ≈ 4–5 g (brand-dependent)
- ¼ teaspoon fine salt ≈ 1.5 g
Troubleshooting Self-Rising Bakes
If a biscuit barely lifts or a muffin domes then sinks, don’t toss the batch yet. Use the table below to spot the likely cause and a fast fix.
| Symptom | Likely Cause | What To Do Next |
|---|---|---|
| Flat, dense crumb | Baking powder too old or under-measured | Mix a fresh batch; measure level; test leavener for fizz |
| Bitter taste | Too much baking powder or overdosed salt | Stick to the ratio; level spoons; whisk evenly |
| Peaked then sunken center | Over-leavened or oven temp low | Use the set ratio; verify oven with a thermometer |
| Uneven rise | Poor mixing; clumps of leavener | Whisk at least 30 seconds; sift if needed |
| Gummy middle | Underbaked or too much liquid | Bake longer; rest batter 5–10 minutes before baking |
| Salty bite | Coarse salt didn’t disperse | Switch to fine salt; weigh if using kosher |
| Pale crust | Low sugar or low heat | Increase temp by 10–15°C (25°F); add a touch of sugar |
Measuring Smart For Reliable Results
Weigh when you can. A digital scale removes guesswork across regions and brands. If using cups, use the spoon-and-level method and avoid packing flour.
Mix in a wide bowl. It gives you space to whisk, which means better distribution of baking powder and salt.
Mind the recipe’s salt. If your batter already includes salty ingredients, ease up on added salt in the mix.
When Store-Bought Makes Sense
Keeping a small bag on hand saves time on busy days. Still, homemade lets you control freshness and salt level, and you can mix only what you need. Many bakers keep both: a bag for speed, a jar for custom batches.

Final Notes
Self-rising flour is just flour, baking powder, and salt in a dependable ratio. Mix it fresh, whisk well, and bake soon for steady lift. Keep a printed ratio near your scale or taped inside a cupboard. Next time a recipe calls for a bag you don’t have, you’ll be set in under a minute.
