Preheat the oven to 350°F. Lightly grease a 9x5-inch loaf pan and line it with parchment paper, leaving some overhang for easy removal.
In a large bowl, add the pumpkin purée, mashed bananas, coconut sugar, melted coconut oil, maple syrup, eggs, and vanilla.
Mix until well combined.
Add the flour, pumpkin spice, baking soda, and baking powder directly to the bowl.
Gently mix with a spatula just until no streaks of flour remain. Don't overmix.
Pour the batter into the prepared loaf pan and smooth out the top.
Bake for 50 to 60 minutes, or until a toothpick inserted into the centre comes out clean or with a few moist crumbs.
Let the bread cool in the pan for 5 to 10 minutes before transferring it to a wire rack. Allow it to cool completely before slicing.
Notes
Use pure pumpkin purée, not pumpkin pie filling. The latter contains added sugar and spices that will throw off the recipe.Measure the flour carefully. Spoon it into your measuring cup and level it off rather than scooping straight from the bag to avoid a dry, dense loaf.Let the coconut oil cool slightly after melting so you’re not adding piping hot oil to the eggs.Check the centre before pulling it from the oven. A toothpick should come out clean or with a few moist crumbs. Wet batter means it needs more time.Cool completely before slicing. This moisture-rich loaf needs that cooling time for the crumb to fully set.Store airtight once cooled. Keep at room temperature for up to 5 days, refrigerate for up to 7 days, or freeze for up to 3 months.
