Cocoa powder vs Unsweetened baking chocolate
Both are pure chocolate, but baking chocolate keeps its cocoa butter while cocoa powder has most of the fat pressed out — so you cannot swap them straight across. To replace 1 ounce of unsweetened baking chocolate, use 3 tablespoons of cocoa powder plus 1 tablespoon of butter or oil to put the fat back. Cocoa powder also comes natural or Dutch-process; match it to whatever your recipe's leavening expects.
