Preheat your oven to 350°F (175°C) and coat two 8x4 inch loaf pans with non-stick cooking spray.

In a medium mixing bowl, whisk together flour, baking powder, baking soda, cinnamon, salt, nutmeg, cloves, ginger, and pumpkin pie spice.

In a larger bowl, beat together eggs and pumpkin puree, then mix in sugar, brown sugar, vanilla extract, and vegetable oil until smooth.

Gradually mix the dry ingredients into the wet mixture until just combined.

Divide the batter evenly between the prepared loaf pans and smooth the tops.

In a small bowl, mix brown sugar, flour, chopped pecans, and melted butter until crumbly, then sprinkle over the batter.

Bake for 50-55 minutes until a toothpick comes out clean.

Cool for about 10 minutes in the pans before transferring to a wire rack to cool completely.
