Substitute for baking-powder in breads
Quick answer
For most quick breads, replace 1 tsp baking powder with 1/4 tsp baking soda + 1/2 cup buttermilk (reducing other liquid by 1/2 cup). This replicates the acid-base reaction that produces lift. If you can't adjust liquids, use 1/4 tsp baking soda + 1/2 tsp cream of tartar as a dry swap.

| Rank | Substitute | Ratio (replaces 1 cup baking-powder) | Notes |
|---|---|---|---|
| #1 | Baking soda and cream of tartar | 1/4 tsp baking soda + 1/2 tsp cream of tartar per 1 tsp baking powder | This is the closest structural equivalent. Cream of tartar is a dry acid that activates baking soda without altering the liquid balance of your dough or batter. The rise and crumb in quick breads like banana bread or Irish soda bread are nearly indistinguishable from the original. Works in a pinch for yeast breads where a small amount of baking powder is called for as a supplemental lift, though those recipes are uncommon. |
| #2 | Baking soda and buttermilk | 1/4 tsp baking soda replaces 1 tsp baking powder; reduce other liquids by 1/2 cup and add 1/2 cup buttermilk | The lactic acid in buttermilk activates baking soda efficiently and adds a mild tang that works well in most savory quick breads and cornbread. This is the approach Serious Eats and King Arthur Baking both default to for quick breads. Requires recipe-level liquid adjustment — skip this if you don't want to do that math, or if your bread already contains a significant acidic ingredient. |
| #3 | Baking soda and plain yogurt | 1/4 tsp baking soda replaces 1 tsp baking powder; reduce other liquids by 3 tbsp and substitute 3 tbsp plain full-fat yogurt | Plain yogurt provides enough acidity to activate baking soda and produces a tight, moist crumb — particularly good in banana bread, zucchini bread, and similar dense quick breads. Full-fat yogurt performs more consistently than low-fat here. The result is slightly denser than baking powder, which is acceptable in most loaf-style breads but less ideal in something like a very light biscuit-style bread. |
| #4 | Baking soda and white vinegar | 1/4 tsp baking soda + 1/2 tsp white vinegar per 1 tsp baking powder | Works in a pinch. The reaction happens immediately and aggressively, so you must get the bread into the oven quickly — most of the CO2 is released before baking even begins. The final crumb is noticeably less open and even than with cream of tartar. Fine for cornbread or soda bread where a dense crumb is acceptable; less suitable for loaves where a consistent rise matters. The vinegar taste is not perceptible after baking. |
Why breads is different
Quick breads rely entirely on chemical leavening — there is no yeast or extended fermentation to build structure. That means the timing and volume of CO2 production from baking powder is the primary driver of crumb texture and rise. In a loaf pan especially, under-leavening produces a gummy, collapsed center, while over-leavening causes the top to dome and crack excessively before the interior sets. Getting the ratio right matters more here than in, say, pancakes, where you can adjust on the fly.
Common mistakes
The most common error is using baking soda alone without any acid source, which leaves an alkaline residue that produces a soapy or metallic taste in the finished bread. A second frequent mistake is using a liquid acid substitute (buttermilk, yogurt, vinegar) without reducing the other liquids — this throws off the dough hydration and can result in a wet, dense loaf. Finally, when using any baking soda–based substitute, overmixing after combining wet and dry ingredients accelerates gas loss before the loaf reaches the oven.
Baking powder does two jobs in quick breads: it provides the acid-base reaction that generates CO2, and because most commercial baking powder is double-acting, it does this in two stages — once when wet and dry ingredients combine, and again when heat is applied. That two-stage release is what gives a loaf time to set its structure before the leavening is exhausted. Cream of tartar plus baking soda is the most reliable dry substitute because it preserves that basic chemistry without touching liquid ratios.
When liquid-acid substitutes like buttermilk or yogurt are your only option, adjust carefully. These acids react with baking soda on contact, meaning you have less working time before the lift is gone. Mix dry ingredients thoroughly before adding wet ingredients, fold minimally, and have the loaf pan greased and the oven fully preheated before you start combining.
Frequently asked questions
- Can I leave out baking powder entirely in a quick bread recipe?
- Not without a replacement acid-base reaction. Quick breads have no other leavening mechanism — omitting baking powder and adding nothing in its place produces a flat, dense, often gummy loaf that is unpleasant to eat.
- Can I use self-rising flour instead of all-purpose flour plus baking powder in bread?
- Yes, with adjustment. Self-rising flour contains approximately 1.5 tsp baking powder and 1/4 tsp salt per cup of flour. If your recipe calls for 2 cups all-purpose flour plus 2 tsp baking powder, you can substitute 2 cups self-rising flour and omit the baking powder and added salt. Check the baking powder quantity against what's already in the flour before using.
- Does the baking powder substitute change how long the bread needs to bake?
- Generally no, but buttermilk and yogurt substitutes can add slight moisture to the batter, which may require an extra 3–5 minutes of bake time. Use a toothpick or instant-read thermometer (195–205°F / 90–96°C internal for most quick breads) to determine doneness rather than relying on time alone.
