Preheat the oven to 350 degrees F.
Cut a piece of parchment paper large enough to cover the inside of the loaf pan and place it inside the pan. Set aside.
In a medium sized bowl, combine the flour, baking soda, baking powder, salt, and spices. Stir with a wooden spoon or spatula to combine. Set aside.
In the stand mixer, whisk the pumpkin puree, eggs, vanilla extract, maple syrup, and softened butter until well combined, making sure there are no large lumps of butter and scraping the sides with a spatula as necessary.
Pour the flour mixture into the pumpkin mixture, stirring until just combined. Add the chocolate chips and stir until well incorporated.
Pour the bread mixture into the loaf pan with the parchment paper in it. Level it out across the pan with the spatula. Add a handful of chocolate chips to the top of the bread, pressing each chip into the mixture slightly.
Place the loaf pan into the oven and set the timer for 30 minutes.
Check the bread after 30 minutes to see how it's cooking. You may need to rotate the pan 180 degrees if your oven cooks unevenly.
Place the loaf pan back in the oven and cook for another 25-30 minutes, until a toothpick inserted into the bread comes out clean.
Once cooked, take the bread out of the loaf pan and let cool at least 10 minutes before serving.
