Use Both Cocoa Powder and Baking Chocolate for Maximum Flavor

Looking for maximum chocolate flavor in your recipe? So are we. In order to best achieve this, use both cocoa powder and baking chocolate if possible because their flavor characteristics combine, resulting in a chocolate explosion. Keep in mind that if you're retrofitting a recipe to have semisweet baking chocolate supplant some of the cocoa powder you should reduce your fat and sugar slightly to compensate.
