Warm afternoon sunshine streamed in through the windows on a cool fall day, illuminating this rich, moist afternoon snack created from a favorite chocolate candy bar. Served with freshly brewed cups of hot tea it was just the thing before a walk into town.

Chocolate coffee cake is tempting straight out of the oven. But this cake tastes best the day after it is baked. The traditional streusel topping turns a good cake into an irresistible afternoon treat.
