Cut the dough into strips about 3 inches wide. Cut each of the strips into 4 to 5 rectangles, each should be about the size of a deck of cards. You should have between 12 and 15 pieces. Sprinkle the pieces with the chopped chocolate, then stack up each one on top of another in a tower. Lay the stack into a loaf pan, like placing books on a shelf.
