Cocoa powder generally contains just 10 to 12% cocoa butter, while pure unsweetened chocolate contains about 55%. So, ounce for ounce, cocoa powder packs a bigger punch of chocolate flavor, because you’re getting more cocoa solids and less cocoa butter.
It has a higher proportion of flavorful cocoa solids than any other form of chocolate, so ounce for ounce, it tastes more intensely chocolaty.
