What we learned: Leavening agents determine the spread, rise, and cakiness of cookies. … Unless you want cakey cookies, avoid using baking powder: The cookies made with both the single- and double-acting baking powders were just too darn cakey. 2. Baking soda helps cookies spread more than baking powder.
In addition, baking powder produces a slightly different texture in cookies than baking soda does. 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.
One trick to keep in mind is that both baking powder and baking soda gives rise, but baking soda also spreads due to its leavening strength in small amounts. Think of what the recipe is trying to ultimately achieve, both taste and texture-wise, and that should give you a clue if you forget which to use.
What happens if you leave baking soda out of a recipe?
Leaving baking soda out of the cake prevents it from rising, but you can use baking powder as a substitute. Baking soda is a salt that makes food light and fluffy. If you don’t have this ingredient at hand, use a baking soda substitute. Without it, your cake won’t rise and can turn out flat.
Baking soda is also typically responsible for any chemical flavor you might taste in a baked good–that bitter or metallic taste is a sign you’ve used too much baking soda in your recipe, and you have unreacted baking soda left in the food. … You may see this described as “double-acting” baking powder.
Those air bubbles are then filled with carbon dioxide from the baking soda and as a result, you get crispy cookies. … Baking cookies for a few extra minutes will also lead to crispier cookies because they have more time to spread out before they firm up. The thinner the cookie, the crispier it will be.
Too much baking soda will result in a soapy taste with a coarse, open crumb.
