• Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with parchment with a bit of overhang for easy removal.
• In a medium bowl, whisk together the flour, baking soda, baking powder, cinnamon, ginger, nutmeg, cloves (if using), and salt until uniformly combined.
• In a large bowl, whisk the granulated and brown sugar with the eggs until glossy and lighter in color, about 1 minute.
• Whisk in the pumpkin puree, oil (or melted butter), and vanilla until smooth.
• Add the dry mixture to the wet in two additions, stirring gently with a spatula until just combined. Fold about 10–15 times until thick and silky, leaving a few streaks to avoid overmixing.
• Fold in nuts, chocolate chips, or dried fruit, if using, taking care not to overwork the batter.
• Scrape the batter into the prepared loaf pan and smooth the top. For a crackly top, sprinkle a tablespoon of turbinado sugar or a few extra chopped nuts on top.
• Bake for 55–70 minutes. Start checking at 50 minutes—insert a toothpick near the center; it should come out clean or with a few moist crumbs. The top should be golden brown and spring back lightly when pressed.
• Let the loaf cool in the pan on a wire rack for 15 minutes, then lift it out using the parchment overhang. Cool another 30 minutes before slicing so the crumb sets.
• Slice with a serrated knife and store leftovers wrapped at room temperature for 2–3 days or refrigerated for up to a week.
