This playful yeast bread brings the classic campfire flavors of chocolate, marshmallows, and graham crackers indoors. A soft, slightly sweet dough made with a blend of whole wheat and all-purpose flours is layered with a rich s'mores filling. The result is a beautiful marbled loaf with a golden, buttery crust and a gooey center. It makes a fantastic weekend baking project that doubles as a comforting breakfast or afternoon treat.
