β Dutch-Processed Cocoa Powder (Best Fat-Free Option)
1:1 replacement (1 tablespoon per 1 tablespoon cocoa powder)Dutch-processed cocoa powder is alkalized to reduce acidity, which can mellow the chocolate flavor and affect the chemical reactions in recipes using baking soda. In bread pudding, which relies mostly on custard setting rather than leavening, this difference is minimal.
Use it as a direct substitute but be aware that the flavor is less sharp and slightly more mellow. It blends well in custard and maintains a smooth texture.
The final pudding will have a softer chocolate note and a darker color, with a slightly less tangy finish compared to natural cocoa powder.
