What is black cocoa?

Last updated June 13, 2026

The most heavily Dutched cocoa available — near-complete alkalization producing a powder that's nearly jet black with a pH of 8.0-8.5. Most famous for being the cocoa in Oreo cookies; the distinctive cookie-cutter dark color and slightly dry, faintly bitter flavor are the black cocoa signature. Usually blended 25-50% with standard Dutch in baking — straight black cocoa is visually dramatic but flavor-flat. King Arthur Double Dark Cocoa Blend is a pre-mixed Dutch + black combo that delivers the dark color without the flavor loss.

Dutch-process cocoa
Cocoa powder treated with potassium carbonate (a mild alkali) after pressing, neutralizing its natural acidity (pH 7.0-8.5 vs natural cocoa's 5.0-6.0), deepening the color, and smoothing the flavor. Named after Coenraad van Houten, the Dutch chemist who patented the process in 1828. Produces a darker, mellower, less acidic chocolate flavor than natural cocoa. Brands: Droste, Valrhona, Cacao Barry, King Arthur Double Dark. Pairs with baking powder (which has its own acid). The default for fudge brownies in this library because the smoother flavor doesn't compete with brown sugar and chopped dark chocolate.
natural cocoa
Unprocessed cocoa powder with its natural acidity intact — pH 5.0-6.0, reddish-brown color, sharper and more fruity-acidic flavor than Dutch-process cocoa. Brands: Hershey unsweetened, Ghirardelli unsweetened. Reacts with baking SODA (a base) to provide leavening in recipes that depend on this pairing; swapping natural for Dutch in a soda-leavened recipe leaves the soda nothing to react with and the bake fails. Works fine in baking-powder recipes (which have their own acid built in) — just expect a brighter, slightly more astringent chocolate flavor.
