Turn into a greater baker by studying the similarities and variations between baking powder vs. baking soda. On this article and accompanying video tutorial, you’ll study why and when to make use of one or the opposite (or each!), in easy-to-understand language—no chemistry diploma required!
In the event you’ve ever puzzled 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 suitable 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)?
One of the vital widespread baking questions I’m requested is whether or not you’ll be able to substitute baking powder for baking soda. The straightforward reply is not any. They’re each leaveners, whose main operate is to make baked items rise within the oven, however they’re chemically completely different.
If there may be one factor that you simply take away from at the moment’s lesson, let 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 develop. These two white powders are each comprised of 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 bear 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? While 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, desserts, and muffins. When a recipe requires baking soda, it often requires some kind of ACID. Widespread acidic substances embody 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 stage of the batter. Making a extra alkaline setting hurries up 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 rationale we boil selfmade smooth pretzels in a baking soda bathtub earlier than baking. Pale pretzels aren’t practically as appetizing!
Baking soda is about 3–4 occasions 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’s going to give your baked items a metallic, soapy aftertaste.
An excellent 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 discuss baking powder.
Baking powder is a combination that accommodates baking soda, in addition to a dry acid to neutralize it—usually cream of tartar—and typically cornstarch (a drying agent).
As a result of baking powder already accommodates 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.
Nevertheless, this isn’t all the time the case. You possibly can nonetheless use baking powder because the leavening agent in recipes calling for an acidic ingredient, notably while you need the flavour of the acidic ingredient to shine by means of, like in a lemon pound cake.
As a result of it’s a combination, baking powder isn’t as robust as baking soda. An excellent rule of thumb is to make use of round 1 teaspoon of baking powder per 1 cup (125g) of flour.
What Is Double-Performing Baking Powder?
Most baking powder bought at the moment is “double appearing.” Which means that the first leavening happens when baking powder will get moist—like while you mix the dry and moist substances within the recipe.
The second leavening happens when the baking powder is uncovered to warmth. That is why it’s often greatest to bake a batter instantly—as a result of the baking powder has already been activated.
An exception to this rule is pancakes, once 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 only some minutes on the new griddle.
Why Do Some Recipes Name for Each Baking Soda and Baking Powder?
The only reply is that typically you want extra leavening than you’ve acid obtainable.
If a recipe accommodates 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 effectively, for essential 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 might neutralize all the buttermilk’s acid and we’d lose that tanginess! Nevertheless, by together with baking powder as effectively (which has its personal acid), among the buttermilk’s taste is left behind, and there may be nonetheless sufficient leavening for fluffy pancakes.
Another excuse to make use of each baking powder and baking soda is as a result of along with inflicting the baked good to rise and develop, in addition they have an effect on each taste and browning.
Let Me Present You the Distinction
To reveal the significance of utilizing the correct amount and sort 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 right 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 possibly can see that it browned an excessive amount of, and in addition sank within the center as a result of the baking soda is just too robust and there wasn’t sufficient acid within the batter to neutralize it. And—you’ll must take my phrase for this—it tasted AWFUL!
Observe the recipe as written with the mixture of baking powder and baking soda for merely good vanilla cupcakes. 🙂
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 ensure they’re recent.
In the event you don’t bake typically, it’s possible you’ll want to check your baking powder and soda for effectiveness earlier than utilizing.
Methods to Take a look at 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.
Methods to Take a look at 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 light-weight 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 accommodates baking soda, plus different substances, 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 cause for that, so make sure you comply with the recipe.
- Each leaveners are initially activated when mixed with moist substances, so bake instantly, except your recipe instructs in any other case.
- Maintain it recent: Change your leaveners 3 months after opening.
Do not forget that baking is science and it takes apply, trial and error, and the willingness to study with a view to succeed.
