Also known as cacao powder.
Unsweetened powder made from roasted, ground cacao beans with fat removed.
Cocoa powder is roasted cacao with most of the cocoa butter pressed out, leaving a fat-light, starch-and-protein-rich powder that delivers chocolate flavor without melting solids. Because it is essentially defatted, it behaves like a dark, bitter flour in batters, contributing color and tannic depth while quietly absorbing liquid and weakening gluten.

Ingredient-specific, density-based conversions for baking
Published values, quoted at the exact measure each source lists. Sources round differently and assume different fill techniques — which is why they rarely agree to the gram.
| Source | Listed measure | Weight |
|---|---|---|
| USDA FoodData Central | 1 tbsp | 5.4 g |
| USDA FoodData Central | 1 cup | 86 g |
| King Arthur Baking | 1/2 cup | 42 g |
CupOrGram standardizes on 82 g per cup (5 g per tablespoon, 2 g per teaspoon) and uses that single value on every page — how we reconcile the sources.

Natural cocoa is acidic (pH ~5), Dutch-process is neutral (pH ~7-8). This affects leavening: natural works with baking soda, Dutch with baking powder.
Dutch-process is the default here — its lower acidity lets butter and brown sugar lead, and the deep mahogany color reads as intensely chocolate. Bloom the cocoa in melted butter for 30 seconds before adding sugar; the fat dissolves the volatile aromatics that water alone leaves locked in the powder.
This is one of the few cakes that genuinely needs natural cocoa. The acidity reacts with baking soda to lift the crumb and produce the slightly russet color the style is named for. Substituting Dutched cocoa without adding an acid like buttermilk or vinegar will give you a denser, browner, less interesting cake.
Sift cocoa with the powdered sugar before adding to softened butter, then bloom a tablespoon of the mixture in a teaspoon of hot espresso or water to pull out flavor. Untreated cocoa in buttercream tastes thin and powdery; bloomed cocoa tastes like ganache.
Baseline reference: 1 cup cocoa powder = 82g. In real kitchens, a practical range is usually 77g-87g per cup (6% band).
Why this happens: fine powders and leaveners settle during storage, changing cup density.
Figures use the US cup (236.6 ml).Only when the recipe is leavened with baking powder, which carries its own acid. If the recipe uses baking soda as the sole leavener, you need natural cocoa's acidity to activate it, or the cake will not rise properly.
Raw cocoa needs heat or fat to release its aromatics. Whisk it into warm cream, melted butter, or hot coffee for at least a minute before incorporating — this blooming step is the single biggest upgrade to icebox cakes, mousses, and frostings.
Yes — black cocoa is ultra-Dutched, alkalized to a pH around 8 for the inky color and Oreo-cookie flavor. It has almost no leavening compatibility and very little fat, so cut it with regular Dutch-process at roughly 1:3 unless you want a dry, intensely dark crumb.
