01 - Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line it with parchment paper.
02 - In a medium bowl, whisk together flour, cinnamon, nutmeg, ginger, cloves, baking soda, and salt.
03 - In a large bowl, whisk pumpkin purée, granulated sugar, brown sugar, eggs, vegetable oil, milk, and vanilla extract until smooth.
04 - Gradually fold the dry ingredients into the wet mixture until just combined to prevent overmixing.
05 - Gently fold in walnuts, pecans, or chocolate chips if desired.
06 - Pour batter into prepared loaf pan and smooth the surface evenly.
07 - Bake for 55 to 65 minutes, or until a toothpick inserted in the center emerges clean.
08 - Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
