Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan and line the bottom with parchment paper.

In a medium bowl, whisk together the dry ingredients: flour, pumpkin pie spice, cinnamon, baking soda, baking powder, and salt.

In a large mixing bowl, combine pumpkin puree, white sugar, light brown sugar, eggs, oil, and vanilla extract. Whisk until smooth.

Fold the dry ingredient mixture into the wet mixture gently until just combined. Do not overmix.

Pour the batter into the loaf pan and bake for 60 to 75 minutes, covering with foil halfway through if necessary.

Let the Pumpkin Bread cool in the pan for 10 minutes, then invert onto a wire rack to cool for another 5-10 minutes before slicing.
