Will cookies bake the same if baking powder is used instead of baking soda? This is an interesting question because if baking powder can replace baking soda, it eliminates the need for both items. It also raises the question regarding if these two ingredients are different. If they are, what different effects will they have on cookies?

Sodium bicarbonate, another name for baking soda, is a soluble white powder used as a leavening agent in baking. Decomposition is a process in which a chemical compound is broken down into simpler matter. Leavening agents are substances that, through the release of gases, cause doughs and batters to rise. Alkaline means that a substance has the opposite effect of an acid. Baking soda is a white alkaline powder.

I will try to avoid this problem by using a measuring spoon to scoop out the cookie dough, so each cookie is the same
