Preheat oven to 350 degree Fahrenheit.
Add the dry ingredients to a large bowl - flour, baking powder, baking soda, cinnamon powder and pumpkin spice and mix everything well so that the ingredients are mixed evenly.
Beat the eggs in a different bowl and add the olive oil and vanilla extract to it, mix very well.
Add the brown sugar also to the egg oil mixture, mix very well to combine. Keep this mixture aside.
In a different bowl (large bowl), mash the bananas and add the pumpkin puree to the mashed bananas. Stir well to combine.
Add the egg olive oil mixture to the pumpkin banana mixture and stir well to combine everything well.
Add the wet ingredients mixture to the dry flour mixture and mix well to combine evenly until there is no dry flour left at the bottom of the bowl.
Transfer ¾th of the batter to a prepared loaf pan and mix in the candies almost evenly (if you are using the candies, otherwise you can just add the whole batter to the pan). Then add the remaining ¼th batter on top (to cover the candies inside the batter).
Bake for about 50 to 55 minutes or until a toothpick inserted at the center of the bread comes out clean. Once the bread is baked, immediately transfer the pan from the hot oven to avoid further baking and allow the bread to cool down completely before you slice and serve! I love serve the pumpkin banana bread slices with a little jam and butter on top!
