Cocoa powder always seems to be more expensive than chocolate bars, so subbing the chocolate bars could be cost effective too.

Editor: Sarah, we presume you are asking about baked good recipes here. (It's quite easy to make hot chocolate or other drinks with chocolate instead of cocoa!) We consulted Joy of Baking (a great web resource for this sort of thing) and it says that you can indeed substitute chocolate for cocoa powder. You do need to add a bit of baking soda, too, and also compensate by slightly reducing the other fats in the recipe.

Readers, any advice on this? Have you ever substituted chocolate for cocoa?
