I'm not too familiar with the two product's properties in baking, and especially not what they need to be used for. I'm wanting to create a egg free peanut butter cookie, and I don't really like any of the recipes I've seen. But when creating a recipe, I wouldn't know whether to use B soda or B powder. Does one make a lighter cookie? Denser?
Any help is greatly appreciated, thank you!

Baking soda is used to make breads as will allow to grow in few hours. Baking powder is used for on the way cooking, like doing packed cakes and such.

It would be better to follow a basic recipe and then "create" something from it. So many factors are involved when using either soda or powder and sometimes both are used. It will depend hugely on your ingredients.
