It is possible to make cookies without baking soda or baking powder, but the resulting cookie will be dense. This is because carbon dioxide is not being produced by a chemical reaction that typically occurs when baking soda or powder is present in the cookie batter.
baking soda allows the ingredients to rise and become airy. Without baking soda, your cookies will be very dense, perhaps not chewy, and not as tasty.
The answer to this is yes, it is totally possible to make cookies without baking soda, as evidenced by how many cookie recipes don’t even call for baking soda.
What to do if you forgot baking powder?
Baking Powder Alternatives
Self-rising flour as a baking powder alternative: Made from a mixture of baking powder, flour and salt, self-rising flour can be used as a substitute for both flour and baking powder in specific baking recipes like biscuits. This results in a light biscuit with a fluffy interior.
Can I leave out baking powder?
If the mixture bubbles up, it’s still good. If not, throw it out. And if it turns out that your baking powder is still good, but your baking soda is not, or vice versa, at least you know how to substitute one for the other.
When softened butter is mixed with sugar, it creates air bubbles. Those air bubbles are then filled with carbon dioxide from the baking soda and as a result, you get crispy cookies.
While baking soda will create a coarse, chewy cookie texture, baking powder will produce a light, fine cookie texture. To achieve the best cookie results, use a double-acting baking powder as a substitute.
