Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line it with parchment paper for easy removal.

Mix Dry Ingredients: In a large bowl, whisk together 2 cups of flour, 1 tsp baking soda, ½ tsp baking powder, 1 tsp ground cinnamon, 1 tsp pumpkin pie spice, and ½ tsp salt until well combined. Set aside.

Combine Wet Ingredients: In another large bowl, beat together 2 eggs, ½ cup melted unsalted butter, and 1 cup sugar until smooth.

Add Mashed Bananas and Pumpkin: Stir in the 4 mashed bananas, 1 cup pumpkin puree, and 1 tsp vanilla extract into the wet mixture until fully incorporated.

Combine Wet and Dry Mixtures: Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to overmix.

Pour into Loaf Pan: Pour the batter into the prepared loaf pan, spreading it evenly with a spatula.

Bake: Place the pan in the preheated oven and bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean.

Cool and Serve: Let the bread cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Slice and enjoy!
