Preheat your oven to 175°C (350°F). Grease a 9x5 inch loaf pan and set aside.
In a large mixing bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg until evenly combined. This ensures the spices and leavening are well distributed.
In another bowl, stir together the pumpkin puree and light brown sugar until the mixture looks smooth and slightly bubbly, about 2 minutes, filling the air with a warm, sweet aroma.
Add the eggs, one at a time, whisking well after each addition until the mixture is thick and glossy. Then, pour in the oil or melted butter and stir until combined.
Gradually fold the dry ingredients into the wet mixture using a spatula, mixing gently until just combined. Be careful not to overmix — the batter should be slightly lumpy but evenly incorporated.
Gently fold in the chocolate chips, distributing them evenly throughout the batter. This creates pockets of melty chocolate in every slice.
Pour the batter into the prepared loaf pan, smoothing the top with a spatula. Tap the pan lightly on the counter to settle the batter and release any trapped air bubbles.
Bake for 55-60 minutes, or until the top is deep golden and a toothpick inserted into the center comes out with moist crumbs. Cover loosely with foil if the crust browns too quickly.
Remove the bread from the oven and let it cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely, which helps the crumb set and prevents crumbling.
Slice the cooled bread with a serrated knife into even pieces. Serve warm or at room temperature, enjoying the moist texture, cozy spices, and melty chocolate in every bite.
