Preheat the oven to 350°F and spray a 9×5 inch loaf pan with non-stick spray. Set aside.

In a large bowl, whisk the flour, baking soda, cinnamon, pumpkin pie spice, and salt together until combined.

In a medium bowl, whisk the eggs, granulated sugar, and brown sugar together until combined. Whisk in the pumpkin, oil, and orange juice. Pour these wet ingredients into the dry ingredients and gently mix together using a rubber spatula or a wooden spoon. Fold in the Hershey's chocolate, graham cracker pieces, and marshmallow bits. Save some of these mix-ins to put on top of the bread once it comes out of the oven.

Pour the batter into the prepared loaf pan. Bake for 60-65 minutes. If the bread appears to be getting too browned on top, feel free to cover it gently with aluminum foil during baking. The bread is done when a toothpick inserted in the center comes out clean with only a few small moist crumbs. Once you take the bread out of the oven, top with remaining Hershey's chunks, graham crackers, and marshmallows. For the added campfire effect, use a mini blowtorch to go over the marshmallows.
