Chocolate Dough
Add 10% cocoa to the base formula and everything changes. The cocoa absorbs water like a sponge, so the dough dries out if you do not adjust it. The cocoa is also acidic, which slows the yeast and weakens the gluten. This recipe is expanded to accommodate both of those effects.
Moisture is supported by more than 20% sugar in the formula. Sugar is hygroscopic, which means it pulls water out of the air and holds it in the bread. The elevated yeast level helps balance the acid and maintain fermentation strength. Without that extra yeast, the dough barely rises.
The result is a bread that is dark, rich, and just sweet enough to eat plain but savory enough to pair with cheese or charcuterie. Slice it thin and toast it for a grown-up snack. Or use it as the base for a chocolate babka by rolling it with a chocolate or cinnamon filling.

Sift the cocoa powder with the flour before you mix anything. Set your oven to 350°F with the rack in the center position, or on a baking stone at the bottom of the oven if you have one. Plan to judge doneness by thermometer rather than color — this dough starts dark and the crust will not give you a clear visual cue.
Line your large loaf pan with parchment paper before you mix. A half sheet fits the pan without cutting. No oiling needed unless you want a buttered crust or plan to add toppings — oil the parchment and sprinkle toppings before the dough goes in. If you are worried about overflow, set the pan on a sheet pan in the oven.
Warm the milk or water to 100°F. Combine it with the yeast, salt, sugar, and melted butter.
Whisk the flour and cocoa powder together in a separate bowl to break up any lumps. Add the dry mixture to the wet ingredients. Mix on low until combined, then increase to medium and mix for 10 to 12 minutes. The cocoa makes the dough feel tighter and less elastic than standard bread dough — that is normal. The dough is ready when it pulls away from the sides of the bowl and has a slight sheen.
Whisk the flour and cocoa powder together. Add to the wet ingredients and mix with a dough whisk or spoon until no dry patches remain. Cover and let it rest at room temperature for 2 to 3 hours, then refrigerate. The longer rest helps the cocoa hydrate fully.
Turn the dough onto a lightly floured surface. Pat into a rough rectangle about as wide as your loaf pan. Fold the top third down, fold the bottom third up, then roll toward you into a tight log. Place seam-side down in the parchment-lined pan.
Cover loosely with plastic wrap. Let the dough proof at room temperature until it rises 1 inch above the rim of the pan, about 90 minutes to 2 hours. The cocoa and its acid slow the proof — be patient and do not rush it.
Bake at 350°F for 50 to 60 minutes. Rotate the pan at 30 minutes. The crust is hard to judge by color because the dough starts dark — rely on the thermometer. The center should read 190°F. Tap the bottom of the loaf; it should sound hollow.
Cool in the pan for 15 minutes, then lift out by the parchment and cool on a wire rack for at least 2 hours. The sugar and cocoa trap more heat than a standard loaf. Cutting too early creates a gummy center.
Slide the cooled loaf into a large plastic bag and seal it. Keeps at room temperature for 4 to 5 days. The high sugar content acts as a preservative and keeps the crumb moist longer than a lean loaf. Wrap tightly and freeze for up to a month. Toast slices from frozen.
