Turn out to be a greater baker by studying the similarities and variations between baking powder vs. baking soda. On this article and accompanying video tutorial, you’ll be taught why and when to make use of one or the opposite (or each!), in easy-to-understand language—no chemistry diploma required!
In case you’ve ever questioned in regards to the distinction between baking powder and baking soda, and why some recipes name for one or each, you’ve come to the appropriate place. Understanding the science behind this straightforward query is important to your baking recipes turning out as anticipated.
Can I Substitute Baking Powder for Baking Soda (& Vice Versa)?
Some of the widespread baking questions I’m requested is whether or not you possibly can substitute baking powder for baking soda. The easy reply isn’t any. They’re each leaveners, whose main operate is to make baked items rise within the oven, however they’re chemically totally different.
If there may be one factor that you simply take away from in the present day’s lesson, let or not it’s this: baking powder and baking soda usually are not the identical, and you shouldn’t substitute one for the opposite in a recipe.

What Are Leaveners?
Baking powder and baking soda are each chemical leavening brokers. You employ leavening brokers—or leaveners—in baking as a result of they assist the dough or batter to rise and increase. These two white powders are each produced from the chemical sodium bicarbonate, which, when mixed with an acid, produces carbon dioxide (CO2). That gasoline is what lifts up your baked items within the oven.
(FYI: Some examples of pure leavening brokers are yeast, eggs, sourdough starter, and steam.)
What Is Baking Soda?
Let’s begin with baking soda, aka bicarbonate of soda.
Baking soda is pure sodium bicarbonate, with nothing else added.
Do you keep in mind the mannequin volcano experiment from grade faculty science class, the place you combine baking soda with vinegar and get an eruption of bubbles? Once you combine baking soda, a BASE (pH worth above 7), with vinegar, an ACID (pH worth beneath 7), you get a chemical response: an eruption of bubbles. A product of this response is carbon dioxide .
The identical response occurs in our cookies, muffins, and muffins. When a recipe requires baking soda, it often requires some sort of ACID. Widespread acidic components embrace buttermilk, brown sugar, yogurt, vinegar, cream of tartar, molasses, applesauce, honey, pure cocoa powder (not Dutch-process cocoa), and lemon juice.
You want this ACID within the recipe to react with the baking soda, which creates carbon dioxide and permits your baked good to rise. Like this no-yeast bread (soda bread), which will get all its carry from the chemical response between baking soda and buttermilk.
Baking soda additionally helps baked items brown higher by elevating the pH degree of the batter. Making a extra alkaline setting accelerates the chemical response that occurs between sugars and amino acids within the presence of warmth, which causes browning and develops taste. In reality, it’s a part of the explanation we boil selfmade tender pretzels in a baking soda bathtub earlier than baking. Pale pretzels aren’t practically as appetizing!
Baking soda is about 3–4 instances stronger than baking powder, so that you don’t want as a lot. Extra baking soda in a recipe doesn’t essentially imply extra carry. You need to use *simply sufficient* to react with the quantity of acid within the recipe. An excessive amount of baking soda and never sufficient acid to neutralize it would give your baked items a metallic, soapy aftertaste.
rule of thumb for baking is to make use of round 1/4 teaspoon of baking soda per 1 cup (125g) of flour.
What Is Baking Powder?
Now let’s speak about baking powder.
Baking powder is a combination that incorporates baking soda, in addition to a dry acid to neutralize it—usually cream of tartar—and generally cornstarch (a drying agent).
As a result of baking powder already incorporates an acid to neutralize its sodium bicarbonate, it’s most frequently used when a recipe doesn’t name for a further acidic ingredient, like sugar cookies or scones.
Nonetheless, this isn’t at all times the case. You may nonetheless use baking powder because the leavening agent in recipes calling for an acidic ingredient, notably if you need the flavour of the acidic ingredient to shine by, like in a lemon pound cake.
As a result of it’s a combination, baking powder isn’t as robust as baking soda. rule of thumb is to make use of round 1 teaspoon of baking powder per 1 cup (125g) of flour.
What Is Double-Appearing Baking Powder?
Most baking powder offered in the present day is “double appearing.” Because of this the first leavening happens when baking powder will get moist—like if you mix the dry and moist components within the recipe.
The second leavening happens when the baking powder is uncovered to warmth. This is the reason it’s often finest to bake a batter instantly—as a result of the baking powder has already been activated.
An exception to this rule is pancakes, after I suggest letting the batter sit for a couple of minutes earlier than cooking. You need to give the primary activation a bit time to begin working earlier than you add warmth, to get these bubbles going so your pancakes stand up good and fluffy in just a few minutes on the new griddle.
Why Do Some Recipes Name for Each Baking Soda and Baking Powder?
The best reply is that generally you want extra leavening than you may have acid accessible.
If a recipe incorporates an acid, just like the bitter cream in my vanilla cupcakes recipe, however the carbon dioxide created from the acid + baking soda is just not sufficient to leaven the amount of batter, we have to add baking powder as properly, for crucial carry.
One other instance for utilizing each is my buttermilk pancakes recipe. On this recipe, you employ buttermilk partly for its tangy taste. If we used solely baking soda, it may neutralize the entire buttermilk’s acid and we’d lose that tanginess! Nonetheless, by together with baking powder as properly (which has its personal acid), a number of the buttermilk’s taste is left behind, and there may be nonetheless sufficient leavening for fluffy pancakes.
One more reason to make use of each baking powder and baking soda is as a result of along with inflicting the baked good to rise and increase, additionally they have an effect on each taste and browning.
Let Me Present You the Distinction
To reveal the significance of utilizing the correct quantity and kind of leavener in your baking recipes, I made 3 batches of vanilla cupcakes.
- I made the cupcakes as written with 3/4 teaspoon of baking powder and ¼ teaspoon baking soda, which is the proper steadiness for this batter.
- I made the cupcakes with 1 teaspoon of baking powder. It didn’t brown sufficient, and it baked up quick and squat as a result of it didn’t rise sufficient as a result of baking powder isn’t as robust as baking soda. The feel was gummy and dense.
- I made the cupcakes with 1 teaspoon of baking soda. You may see that it browned an excessive amount of, and in addition sank within the center as a result of the baking soda is simply too robust and there wasn’t sufficient acid within the batter to neutralize it. And—you’ll should take my phrase for this—it tasted AWFUL!

Make Certain They’re Recent
Regardless of which leavener you’re utilizing in your baking recipe, I like to recommend changing baking powder and soda each 3 months, to verify they’re contemporary.
In case you don’t bake usually, chances are you’ll want to check your baking powder and soda for effectiveness earlier than utilizing.
Check Baking Powder for Freshness
To check baking powder, pour 3 Tablespoons of heat water right into a small bowl. Add 1/2 teaspoon of baking powder. Give it a stir. The combination ought to reasonably fizz if the baking powder is efficient.
Check Baking Soda for Freshness
To check baking soda, pour 3 Tablespoons of white distilled vinegar right into a small bowl. Add 1/2 teaspoon of baking soda. Give it a lightweight stir. The combination ought to quickly bubble if the baking soda is efficient.
Key Takeaways:
- Baking soda is pure sodium bicarbonate. Use baking soda when the recipe requires an acidic ingredient.
- Baking powder incorporates baking soda, plus different components, together with a dry acid. Use baking powder when there’s no extra acidic ingredient within the recipe.
- In case your recipe requires each baking soda and baking powder, there’s a purpose for that, so remember to comply with the recipe.
- Each leaveners are initially activated when mixed with moist components, so bake instantly, except your recipe instructs in any other case.
- Hold it contemporary: Substitute your leaveners 3 months after opening.
