Preheat the oven to 350 degrees and grease a loaf pan.
In a large mixing bowl, stir together the flour, pumpkin pie spice, baking powder, baking soda, and salt. Set aside.
In a separate mixing bowl, mash the bananas, measuring them after they've been mashed. Whisk in the coconut sugar, pumpkin, oil, eggs, and vanilla until smooth.
Add the dry ingredients and stir until just combined, try not to overmix.
Pour the batter into the prepared loaf pan and bake in the preheated oven for 60-65 minutes, or until a toothpick inserted in the middle comes out clean.
Allow the bread to cool completely, then slice and serve!
