There are two types of cocoa we use most often for baking - Dutch process and natural. Natural cocoa powder is the most common. It's the most natural of cocoa powders, hence its name. Natural cocoa powder is lighter in color and used in recipes with baking soda, where the acid in the cocoa is neutralized, enhancing the cocoa flavor. Dutch processed cocoa is alkalized to reduce the acidity. It makes the cocoa powder darker, smoother and more mild in flavor. This type of cocoa powder does not need baking soda to neutralize, so it is commonly used in recipes with baking powder. Black cocoa powder is similar to Dutch process, except that it is heavily alkalized. It's deep and bittersweet in flavor, though, depending on the recipe, black cocoa is often used in conjunction with another cocoa powder to give the baked good more of a balanced, multi-faceted chocolate flavor.
