Activate the Yeast: Combine the sugar, yeast, and warm water in the bowl of a stand mixer. Let stand for 5 minutes until the mixture becomes foamy and the yeast is activated.
3 tablespoons granulated sugar, 1 packet active dry yeast, 1½ cups warm water
Add the Sweeteners: Add the molasses, honey, and softened butter. Stir briefly to combine.
4 tablespoons molasses, 2 tablespoons honey, 2 tablespoons unsalted butter
Combine the Dry Ingredients: In a separate bowl, whisk together the whole wheat flour, all-purpose flour, cocoa powder, and salt.
2½ cups whole wheat flour, 1 cup unbleached all-purpose flour, 2 tablespoons cocoa powder, 1 teaspoon salt
Mix the Dough: Using a stand mixer fitted with a dough hook, gradually add the dry ingredients to the yeast mixture. Mix on medium-low speed until a soft dough forms.
Knead Until Smooth: Continue kneading for 6–8 minutes. The dough should become smooth and elastic, pulling away from the sides of the bowl. If it remains excessively sticky, add additional all-purpose flour 1 tablespoon at a time until a cohesive dough forms.
Shape and Pan the Dough: Lightly grease a 9 x 5-inch loaf pan. Shape the dough into a loaf and place it into the prepared pan. If desired, sprinkle rolled oats over the top for a rustic finish.

Let the Dough Rise: Cover the pan with a clean kitchen towel and allow the dough to rise for approximately 1 hour, or until doubled in size. For a warmer proofing environment, place the covered loaf in an oven with only the oven light turned on.
Preheat the Oven: Preheat the oven to 375°F (190°C).
Bake the Bread: Place the loaf in the oven and immediately reduce the temperature to 350°F (177°C). Bake for 30 minutes, or until the loaf is deeply golden brown and sounds hollow when tapped on the bottom.
Cool Before Slicing: Remove the loaf from the pan and transfer it to a wire rack. Allow it to cool completely before slicing to preserve the soft texture and structure of the crumb.
