This recipe makes 1 large loaf of fluffy, soft chocolate bread with chunks of chocolate and walnuts throughout.
In a large mixing bowl, combine the rest of the water, sugar, and salt. Stir to dissolve. Add the risen yeast mixture, and then add the butter, chocolate chips, and walnuts.
Combine the water, sugar, and salt in the bowl of the electric mixer, and add the yeast, butter, chocolate chips, walnuts and cocoa to that. Use the dough hook attachment and mix in 1 c. flour until it is well incorporated. Add more flour and mix, again until incorporated. Keep doing this until you get the consistency of a smooth, soft dough. Turn into a greased bowl and cover to rise.
Let the dough rise for 1 hour or until doubled in bulk. Grease your hands with a bit of oil or butter and punch the dough down. Divide into 2 sections, and roll between your hands until you get two 15" ropes.
Twist the ropes together into a long loaf, pinching the edges to seal, and tucking the ends under to finish.
Alternatively: You can shape the dough into a loaf and set it into a lightly greased loaf pan.
Set the loaf onto a non-stick, parchment lined, or lightly greased pan. Cover loosely with a tea towel, and allow to rise 35 minutes. Preheat the oven to 350 degrees F and allow the oven to heat 10 minutes (for a total rising time of 45 minutes).
Cool completely on wire racks before slicing. Store in a sealed container or plastic bag.
