Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line it with parchment paper for easy removal.

In a medium bowl, whisk together the flour, baking soda, baking powder, cinnamon, nutmeg, and salt. Set aside.

In a large mixing bowl, combine the granulated sugar, brown sugar, pumpkin puree, vegetable oil, eggs, and vanilla extract. Mix until smooth and well combined.

Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.

Fold in the chocolate chips until evenly distributed throughout the batter.

Pour the batter into the prepared loaf pan and smooth the top with a spatula.

Bake in the preheated oven for 60-70 minutes, or until a toothpick inserted into the center comes out clean.

Allow the loaf to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
