Pure cocoa powder (Very dark, 22/24% fat cocoa.)
Natural Unsweetened Cocoa Powder will taste very bitter and produces a deep chocolate flavor your baked goods. The intense flavor makes it a good choice for brownies, cookies and some chocolate cakes. When natural cocoa (acidic) is used in recipes calling for baking soda (alkali), it creates a leavening action that causes the batter to rise when it is introduced to heat (oven).
