Chemical leavening agents like baking soda and baking powder can have a profound effect on your favorite baked goods – but what is baking soda vs. baking powder? How do they actually work? What are the differences between them?

Those are the questions I’ll be answering for you today, and guess what… I brought VISUALS! Let’s dive in!

Baking Soda vs. Baking Powder

What Are Chemical Leaveners? Can You Substitute Baking Powder For Baking Soda And Vice Versa?

Baking Powder and Baking Soda are both chemical leaveners that work to create light textures in baked goods. They release gases, primarily carbon dioxide, through chemical reactions between acids and bases – but both only work under the correct conditions. Although baking powder actually contains baking soda, the two leaveners are very different and cannot be simply swapped in recipes.

Baking Powder And Baking Soda Both Provide Three Similar Main Functions

  1. Leavening: Baking powder and soda release gases that form bubbles, which expand within the batter or dough during the baking process. The protein in the batter or dough then sets around those air pockets. This creates rise and lift in the structure of your baked goods.
  2. Tenderizing: As the gases form and expand, cell walls in baked goods begin to stretch and thin. This results in a more tender texture that’s easier to eat.
  3. Provide flavor: Small amounts of chemical leaveners can contribute a salty, sour flavor that is distinct to baked goods like biscuits, scones, or Irish soda bread.

Why It’s SO Important to Use a Leavener in Most Recipes

Take a look at the image below to see what happens when NO chemical leavener is used in my Ultimate Muffin Recipe, compared to using both baking powder and baking soda. The muffins without any leavener are extremely dense and almost taste unbaked, despite being baked for the exact same amount of time as the other!

What is Baking Soda and How Does It Work?

Baking soda, also known as bicarbonate of soda and referred to scientifically as sodium bicarbonate, is a natural pure alkaline substance, activated by moisture and acid present in the batter or dough, to produce gas. There must be some acidic ingredient in the recipe for baking soda to function. Naturally acidic ingredients that will activate baking soda include:

  • Buttermilk
  • Sour cream
  • Yogurt
  • Lemon juice
  • Honey
  • Natural aka unsweetened cocoa powder (NOT Dutch-processed)
  • Unsweetened chocolate
  • Brown sugar
  • Molasses
  • Fruits & fruit juices

Baking soda begins to leaven as soon as it touches the liquid present in the dough or batter. This means that if you wait too long before baking, you may notice a decrease in leavening effect (especially in wetter dough or batters).

In professional baking, this is referred to as ‘bench tolerance,’ or how long a batter or dough can be stored before it has lost its leavening. For recipes that rely mostly on baking soda for their structure which are also full of moisture, such as certain cake batters, they shouldn’t be stored too long before baking.

If you use too much baking soda, you may taste an unpleasant metallic, soapy, or bitter flavor in your food. This can happen by accident by mismeasuring or when making other changes to an established recipe.

How Baking Soda Changes Baked Goods

  • Baking soda elevates pH.
  • Baking soda helps add a beautiful browned color to baked goods by elevating pH levels.
  • A higher pH in baked goods can affect color, flavor, texture, and gluten development! For example, baking soda in brownies or gingerbread enhances the deep dark color and smoothes out the chocolate flavor.
  • Baking soda is also present in baking powder, but in a smaller amount, so it has a lower pH level which results in less browning.
  • Baking soda in cookies leads to more spread and a crispy edge compared to baking powder, as shown in the photos below.

How to Test Baking Soda for Freshness

Since baking soda must be fresh to work properly, it’s important to switch out your container before the expiration date. However, baking soda can lose its effectiveness even before that date. Here’s how to ensure your baking soda is still effective:

  • Place 1/4 teaspoon baking soda in a bowl and pour 1 teaspoon of distilled vinegar on top.
  • If the baking soda immediately bubbles violently, it is fresh.
  • If nothing happens, throw away the baking soda and buy a new package.

    What is Baking Powder and How Does it Work?

    Baking powder is a combination of:

    • Baking soda
    • An acid (usually cream of tartar)
    • An anti-caking agent (such as cornstarch)

    Because it contains both the acid and the base necessary for the desired chemical reaction, your batter or dough doesn’t require additional acidic ingredients to work properly. All baking powder needs to be activated is moisture and heat! This makes baking powder a complete leavening system.

    Most products available in the U.S. today are double-acting baking powders, meaning it reacts twice. Its first reaction occurs when combined with liquid to help aerate the batter or dough, and a second more slow-acting reaction occurs when heated in the oven. This means that baking powder-leavened doughs and batters have a better bench tolerance and can be stored and baked at a later time. If using aluminum-free baking powder, I recommend looking for one that is also marked as double acting, for best results.

    How Baking Powder Changes Baked Goods

    • The small amount of cream of tartar in baking powder decreases pH and weakens gluten.
    • In recipes like muffins, biscuits, and cakes, many of which rely entirely on baking powder, this results in a tighter, whiter, and delicate texture.

    How to Test Baking Powder for Freshness

    Baking powder can lose its effectiveness before the expiration date. Here’s how to check it’s still active: 

    • Place 1 teaspoon of baking powder in a small bowl with 1 cup of hot water from the tap.
    • If it bubbles up, the baking powder is fresh.
    • If nothing happens, throw the baking powder away and buy a new container.

    Why do Some Recipes Not Call for Baking Powder or Baking Soda?

    The recipes where you don’t need a chemical leavener are usually:

    • Recipes using yeast, which is an organic leavener that also works by producing gas bubbles (like bread)
    • Baked goods that whip lots of air into the batter, or use whipped egg whites to leaven (like certain types of cake, such as a Angel Food Cake)
    • Or are custard-based (like ice cream or crème brûlée), where rich creaminess is the desired texture.

    Strength of Baking Powder vs. Baking Soda

    It’s important to understand that baking soda is four times stronger than baking powder. This means 1 teaspoon of baking powder will raise a cup of flour, whereas only a 1/4 teaspoon of baking soda can produce the same effect. A general rule of thumb is that ½ teaspoon of baking soda is neutralized by 1 teaspoon of lemon juice or vinegar.

    How to Store Baking Powder and Baking Soda

    Purchase in the smallest size feasible based on how often you bake and use chemical leavening agents. Store in a cool place in an airtight container. Air and light can cause them to lose their effectiveness before their expiration date, which is why I included freshness tests above.

    Which is Better: Baking Powder or Baking Soda?

    Neither one is better than the other, they are simply used depending on the chemistry of the recipe, how it will be handled, and what the desired outcome is.

    Take a look at some of the experiments Team Handle the Heat performed using baking powder and baking soda.

    Below you’ll see the same exact base muffin recipe baked in the same trays at the same temperature for the same amount of time. The only difference is the chemical leavening agent used.

    • Baking powder muffins: These were tall, light, slightly delicate, fluffy, and cakey. They were evenly domed on top. These were my favorite, followed by batch 3 which contained both.
    • Baking soda muffins: These were slightly more browned, they had very tall peaks in the center, and they had an ever so slightly sour taste. Almost like there was sour cream in the batter (there wasn’t).
    • Both baking soda and powder muffins: These muffins were the most browned and caramelized and had a more springy texture.
    • No leavener muffins: These were leaden, dense, rubbery, and really just a doughy, inedible mess.

    We repeated the same experiment with my Bakery Style Chocolate Chip Cookie Recipe.

    • Baking powder cookies: These were extra thick and tall, not chewy, more fluffy, and not quite as flavorful.
    • Baking soda cookies: These cookies were well browned with slightly crispy edges, chewy interiors, and regular thickness. They didn’t stale as quickly so they were more shelf stable. They were my favorite!
    • No leavener cookies: These were dense, heavy, and had a similar texture to Mexican Wedding Cookies.

    Why do Some Recipes Use Both Baking Soda and Baking Powder?

    As you can see above, sometimes we want the best of both worlds! Some recipes call for both baking soda and baking powder in order to have the highest effect of acid-neutralizing and leavening powers.

    This works especially well for an acidic dough that needs to be stored overnight, such as my favorite Ultimate Chewy Chocolate Chip Cookie recipe.

      Found your website early this year. Just love it. The question I have is about ovens. I’ve made several of the recipes, most recently the Cosmic Brownies, twice. Both times I believe I over cooked them using the CONVECTION BAKE setting on my Electric oven. I’m a firm believer that electric ovens, generally have a more even, constant temperature, and using the convection fan makes a difference in the cooking. Wondering if you might have thoughts about using, or not using convection. Possibly even suggest baking time with convection ovens. Appreciate any thoughts or comments. Blessings

        Hi Keith! Glad to hear that you’re enjoying Tessa’s recipes and baking science articles! You seem to be right about electric ovens – across our whole Handle the Heat team, those with gas ovens struggle with maintaining temperature and need to bake most things a little longer than those with electric ovens. The convection setting on ovens can be a terrific asset, but they do tend to bake hotter and faster than the conventional setting. Some ovens will automatically adjust the temperature down, but others need to be manually adjusted. If your oven isn’t doing this for you, lower the temperature by about 25°F from what is stated in the recipe. If you don’t already have one, Tessa strongly recommends investing in an oven thermometer. They’re inexpensive and take the guesswork out of oven temps! Learn more about ovens and using an oven thermometer (as well as Tessa’s recommendations) in her Ovens 101 article here. I hope this helps! Happy baking 🙂

      Hi Tessa,
      Thank you for your generous explanation. I refer to your explanation on ‘bench tolerance,’ for baking Soda. How long actually the batter with Soda can be stored before we bake them? Can we prepared the batter (with baking Soda inside),and put them immediately in fridge and bake them the next morning ? Thanks

        Hi Karen! We are so glad to hear that you’re enjoying reading all Tessa’s wonderful science of baking articles! It’s so incredible to hear that you’re loving learning from Tessa’s science of baking content, especially with such an impressive background! Tessa does have a couple of cookbooks, but they are only available online. You can check out her book on ice cream sandwiches here, and her cookbook on cookies (including lots of science of baking tips!) here! If those links aren’t working or are taking you to the wrong book, it may be because you’re located outside the US, so all you have to do is this: switch your Amazon store to the US store, and search for “The Ultimate Cookie Handbook by Tessa Arias” and it should come right up! Thank you for reaching out, Karen, and happy baking! 🙂

      Hello, I have followed your work for 4 years. With each article, I appreciate your evidence based approach, but the lack of references and citations is bothersome. Some of the text closely resembles excerpts of other cookbooks, which should be cited if it is the source. Demonstrating another’s work is not original work and deserves a citation. What is your explanation for the lack of citations and references?

        Jean H — June 25, 2022 at 6:43 pm

        She is not citing any information that would be dimmed worthy of citation. She made the experiments herself. She is using knowledge she got in school, thus available on any text book. I personally find your comment a bit shady.

      Hi Tessa
      I’m from Australia and I stumbled on to to your website after learning about “double acting baking powder” (DABP) as I had just made a batch of muffins and of course once you start researching the WEB you pretty much bounce around from site to site.
      Now, DABP isn’t common in our supermarkets but it is available if you look. I believe i do have an understanding of how baking soda and BP work, but what I don’t understand is what the difference in the “aluminium free” (AF) DABP besides the metal taste of course. My research was going well right up to “AF”, I got confused because I want to trial chilling my muffin batter overnight in the fridge and to my understanding (and please accept my apologies in advance if I got it wrong) if it’s AF then it doesn’t work as well? I rephrase my question another way just in case I’m not asking the correct question. If I’m chilling muffin batter does “DABP” work the same way as “DABP AF”, which do I use?

      • #
        Emily — October 11, 2021 at 11:28 am

        Hi Sophia! Aluminum-free baking powders primarily react only with liquid and not with heat, which makes them react more quickly to your batter than most double-acting powders. With an aluminum-free baking powder, you will want to get your muffins into the oven right away as the longer you wait, the less rise you’ll get. Using an aluminum-free baking powder that is double acting will allow you to chill your muffins. Our favorite brands of baking powder are Clabber Girl, which contains aluminum, or Argo, which is aluminum-free but double acting. I hope that helps! Thanks for asking, I’ll see if Tessa can add more details to this post regarding aluminum-free baking powder.

      If the cookie recipe I use only calls for baking soda, won’t freezing the dough inactivate the baking soda?
      Should I adjust the recipe to include baking powder? If so, how much baking powder?

      Does the acidity make rise the dough ? I don’t understand why we don’t use baking powder after using baking soda.. when the acidity is neutralized, but we don’t add any other leaveners, does it still rise evenly ?

      I have a recipe that uses single acting baking powder. I have used Alsa baking powder which is single acting, but it gives off a weird smell. I’ve been searching on the web how to make my own single acting baking powder but the ratio of cream of tartar to baking soda was either a 2:1 or 3:1 etc, which is correct please?

      Also one time, I added a bit much(forgotten and used a Tablespoon instead of teaspoon) of baking soda and baking powder, the cake came out bitter, is this due to the baking soda or baking powder?

      I found your video by searching for baking soda vs. baking powder. It was exactly what I needed to know. I have a recipe for oatmeal pecan cookies that I have used for years, just as it is written. It contains brown sugar and baking soda. Never before had I realized the “acid” required to activate the soda was in the brown sugar. I should have checked before I completed the recipe, because I switched to baking powder this time, thinking that I had been doing it incorrectly for 50 years. I thought perhaps the church lady who gave me the recipe had gotten it wrong. I won’t know until the dough chills and I bake them, but I have a feeling I am going to regret my decision. But NOW, I know. Thank you for the insightful information.

        Hi John – you are so welcome! Cookies without baking soda won’t spread or brown as much. How did they turn out?

      Thank you, Tessa. This is informative. The cookies looks soooo good!!!

      May I ask if you have already tried baking with less sugar and putting in substitute like Stevia and or Erythritol?

      Hi, I just stumbled across your website through reading about your cake flour article & enjoyed it. Than I came to this one & was wondering two things first what about cream of tartar? Second have you heard of the DIY baking powder? What I’ve come across is you substitute 1/2 teaspoon baking soda & a 1/4 teaspoon cream of tartar for 1 teaspoon baking powder. I’ve found it works in a pinch but I’ve never done any side by side comparisons & I have noticed the baking soda flavor in some of the more delicate flavors of my baked goods. Just curious?

      I have a recipe for ginger cookies that calls for two teaspoons baking soda, and they come out very thin. Should I use one teaspoon each of soda and powder? The recipe does call for refrigeration.
