Preheat your oven to 350°F (175°C) and grease a 9x5 inch loaf pan with oil or line it with parchment paper.
In a large mixing bowl, combine the pumpkin puree, applesauce, honey (or maple syrup), eggs, and vanilla extract. Whisk together until smooth and well blended.
In a separate bowl, mix together the whole wheat flour, cocoa powder, baking soda, baking powder, salt, cinnamon, and nutmeg until fully combined.
Slowly add the dry ingredients to the wet mixture, stirring until just incorporated. Be careful not to overmix.
Fold in the dark chocolate chips, reserving a few for topping if desired.
Pour the batter into the prepared loaf pan, smoothing the top with a spatula. Sprinkle any reserved chocolate chips on top.
Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean. If the top starts to brown too quickly, you can tent it with foil during the last 15 minutes of baking.
Once baked, allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Notes
Serve with Greek yogurt or almond butter for added flavor.
