Preheat your oven to 350°F (175°C) and grease a loaf pan.
In a large bowl, mash the ripe bananas with a fork until smooth.
Add the pumpkin purée, eggs, sugar, oil, and vanilla extract to the mashed bananas. Stir until everything is combined.
In another bowl, whisk together the flour, baking soda, cinnamon, nutmeg, ginger, and salt.
Slowly add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix the batter.
Pour the batter into the greased loaf pan and smooth out the top.
Bake for 50 to 60 minutes, or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
