Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line with parchment.
In a medium bowl, whisk flour, baking soda, baking powder, salt, and spices.
In a large bowl, whisk pumpkin puree, oil, sugars, eggs, vanilla, and milk until smooth.
Fold dry ingredients into wet, mixing gently until just combined. Do not overmix.
Pour batter into loaf pan. Bake 50–60 minutes, or until a toothpick inserted in the center comes out clean.
Let bread cool in pan 10 minutes before transferring to a wire rack. Slice and enjoy!
