Preheat oven to 350 degrees F.

In a bowl, stir instant coffee into warm water. Add yeast, stir to combine, and set aside to let yeast bloom.

In a large bowl, mix together sugar, cocoa, salt, oil, and yeast mixture. Add all the molasses and half the flour. Mix until just combined. Continue adding flour until the dough pulls away from the bowl. The dough will be sticky, but manageable.

Transfer the dough to a large bowl that has been coated with non-stick cooking spray. Cover with a kitchen towel, and allow the dough to double in size - about 2 hours.

Transfer dough to a loaf pan. Beat together egg white and water. Brush top of loaf with egg wash and sprinkle with rolled oats.

Bake for 30 to 40 minutes, of until a toothpick inserted in the center comes out clean.
