What Does Baking Soda Do In Cookies? ›

Baking soda and baking powder are both leaveners made from a chemical called sodium bicarbonate. When sodium bicarbonate is combined with an acid, it produces a gas (carbon dioxide, C02, the same gas we exhale when we're breathing) that lifts cakes, cookies or other baked goodies while they're in the oven.

This release of carbon dioxide causes the dough or batter to rise, resulting in baked muffins and cakes that are fluffy and airy. Using just baking soda, however, will result in the chemical reaction occurring in the mixing bowl and not in the oven, explains North Carolina State University_.

Mix in something acidic

Use a small amount of an acidic condiment such as lemon juice or vinegar to neutralise the soda. If the recipe has chocolate, simply add half a teaspoon of cocoa powder to it. Buttermilk can also be used to counter the pungent taste of baking soda.

Both baking powder and baking soda are chemical leavening agents that cause batters to rise when baked. The leavener enlarges the bubbles which are already present in the batter produced through creaming of ingredients.

As with baking soda, the purpose of baking powder is to create air bubbles that give your baked goods their light, airy texture. There are two types of baking powder: single action and double action. Single action baking powder creates the carbon dioxide bubbles upon contact with moisture, similar to baking soda.

When baking soda is mixed with an acid and a liquid, it will create bubbles of carbon dioxide gas that give it a fluffy texture. That being said, baking soda can react without acid if it is warmed above 122°F or subject to long-term heat and humidity.

You technically can leave out baking soda in certain recipes (like chocolate chip cookies or pancakes) in a pinch, but you need to understand that your finished product will not be as light and fluffy as the recipe intended. Unless you have no other option, you really should use a leavening substitute.

If you don't have baking soda, you can use baking powder, at three times what the recipe calls for. So if a recipe calls for one teaspoon of baking soda, you can use three teaspoons of baking powder. Baking powder also contains a little bit of salt, so it's also a good idea to halve the salt the recipe calls for.

Using too much baking soda.

Baking soda encourages spreading while baking powder puffs the cookies up. If your recipe calls for 1 teaspoon of baking soda, you would use 3 to 4 teaspoons of baking powder. Caution: This could result in an unwanted flavor shift.

Yes, baking powder and baking soda can expire! Once they've been opened, it's best to use them within six months, so make sure to check expiration dates before you start baking. Expired leavening agents lose their effectiveness, leading to flat cookies.

Is 1 teaspoon of baking soda too much? ›

Typically, a daily dose of 1/2 teaspoon of baking soda per day is recommended. Too much baking soda may cause diarrhea, stomach disturbances, gas, headaches, nausea, swelling, or vomiting.

Using the wrong leavening agent

If you accidentally add baking soda instead of baking powder to baked goods, they won't rise because there is not enough acid.

Baking soda also serves another important purpose when it comes to cookies: It encourages spreading by raising the mixture's pH, which slows protein coagulation. This gives the dough more time to set before the eggs set, which results in a more evenly baked cookie.

Without baking soda or baking powder, these cookies will remain a little flatter then other recipes but because of the eggs and creaming of the butter and sugars in this recipe they will still puff up a little in the oven. They will have crispy edges and a soft, chewy center.

They rise.

The baking soda then reacts to the acidic components present in brown sugar, creating gases that cause the cookie to rise.

The recipe for The Best Chocolate Chip Cookies claims that the addition of a small amount of water, “creates steam as [the cookie] bakes, working with the baking soda to puff the cookies up.” Others claim mixing warm water with baking soda helps remove clumps and disperses it with the other ingredients in the recipe.

Baking powder, in particular, is one of those ingredients you can easily run out of without noticing, but when it comes to baking, it does a very particular job, and can be difficult to replace. Most baked goods need a leavening agent to make them rise, and if you leave it out, your cake or your cookies will fall flat.

Putting a slice of fresh white bread in the container with the cookies will help the cookies stay soft: fresh bread is moist, and that slice will give up its moisture for the greater good: keeping the cookies from drying out. We recommend white bread so that no flavor is transferred to the cookies.
