Pumpkin Banana Bread

Preheat oven to 350° and grease a loaf pan with cooking spray. In a large bowl, whisk together flour, cinnamon, salt, baking soda, baking powder, and ginger.  In another large bowl, whisk together melted butter, sugar, egg, and vanilla. Add pumpkin puree and mashed bananas and whisk until combined. Add dry ingredients and mix until just combined.  Pour batter into prepared loaf pan and top with pumpkin seeds. Bake until a toothpick inserted in the middle comes out clean, 1 hour to 1 hour and 10 minutes. Let cool before slicing.
