• Preheat oven to 350°F. Grease a loaf pan and line it with parchment paper, if desired. Set aside.

Making the batter

• In a large bowl, combine the mashed bananas, pumpkin puree, brown sugar, melted butter, eggs, and vanilla extract. Whisk until everything is mixed together.
• Add in the flour, baking soda, baking powder, salt, cinnamon, and allspice. Whisk until batter is smooth and everything is combined. Pour batter in the prepared loaf pan.

Making the Streusel

• In a medium-sized bowl, combine all of the streusel ingredients. Mix together with a fork until everything is mixed together and clumps form.
• Sprinkle evenly on top of the bread batter.

Baking the Bread

• Pop in the preheated oven and bake for 50-55 minutes, or until a toothpick comes out clean. Allow to cool completely before removing from pan and slicing. Enjoy!
