You can use both to cook. However, if you meant to ask if you can substitute one for the other, you can't. (Not on a 1:1 ratio.) Baking soda is stronger. 1 tsp baking soda= 3tsp baking powder; but substituting one for the other may alter the outcome of your recipe, which isn't necessarily bad in every case.
Baking soda and baking powder are both chemical leaveners used to make baked goods such as cakes and muffins. Baking soda has some other culinary uses, not discussed here. In recipes calling for baking powder, baking soda can be used, along with some cornstarch and cream of tartar. Baking powder cannot, however, be used to replace baking soda.
I have seen quite a few recipes where it does suggest mixing up a batter/dough which includes baking powder and then baking it later (flatbreads, pancakes and American muffin batters, among others). I've only tried it with flatbreads and it did work, but I'm not sure how well it would turn out with liquidy batters (such as muffins).
If you really want to make sure it still rises, consider using "double action baking powder" -it reacts upon moisture being added and upon heating, so it should still rise when baked.
if the recipie says to use baking powder you should use that as that is how it is sopose to be used but you may try and use baking soda if you don't have baking powder
yes you should use baking powder in scones because that makes the scones rise when they bake.
You cannot use baking powder as a substitute for baking soda
Baking powder is a raising agent commonly used in cakes, biscuits, etc. If a recipes calls for baking powder, you should use it as it performs the important function of producing gases during the baking process which creates lift and aeration. If you do not use baking powder, where indicated, you will find that your cake will not rise or your biscuits will be flat and lifeless! There are, of course, lots of recipes which do not need baking powder. Also, self raising flour already contains a set quantity of raising agents and therefore recipes which use this as an infgredient are less likely to need further raising agents such as baking powder or sodium bicarbonate.
Yes, you can use self rising flour to bake a cake. Just leave out any baking soda, baking powder or salt called for in the recipe, as these are already included in self rising flour.
You could use yeast instead of baking powder.
No, you can substitute buttermilk for milk but not for baking powder.
Baking powder allows the dough to rise, and is often used with salt.
Baking soda is required to leaven the baked product. Either baking soda or baking powder would need to be included in the batter regardless of the use of cocoa powder.
you could use baking powder but its best to use dry active yeast
no
i usually use baking powder, not baking soda
