Preheat oven to 350 degrees. Spray a 9x5-inch loaf pan with nonstick cooking spray. Set aside.

In a large bowl, whisk together flour, baking powder, baking soda, salt, cinnamon and pumpkin pie spice. In a medium bowl, whisk together granulated sugar, brown sugar, pumpkin, vegetable oil and eggs until well combined. Add to the dry ingredients until just combined and no flour streaks remain.

Pour the batter into the prepared pan. Smooth the top with a spatula. Bake for 50-60 minutes or until a toothpick inserted in the center of the loaf comes out clean.

Remove from the oven and cool slightly on a wire rack with wax paper underneath the rack before topping with glaze.

In a small bowl, whisk together glaze ingredients. If mixture appears too thick add another tablespoon of milk. Pour the glaze over the loaf while still warm.
