Preheat the oven to 350°F (175°C) and grease a 9×5-inch loaf pan.
Whisk together the flour, baking soda, spices, and salt.
Combine the eggs, pumpkin, sugars, oil, and vanilla in a separate bowl.
Pour the dry ingredients into the pumpkin mixture.
Fold gently until no large flour streaks remain.
Transfer the batter to the prepared loaf pan and smooth the surface.
Bake for 55–65 minutes, checking the center with a toothpick.
Cool for 15 minutes in the pan, then move the loaf to a wire rack.
