These Pumpkin Banana Muffins are such a delicious and easy-to-make fall treat! They're perfect for breakfast, brunch, or fall-inspired dessert. These delicious muffins are light, fluffy, moist, and flavorful, and the streusel topping adds the most perfect touch of sweetness and crunch!
Preheat the oven to 350 degrees F. Line a muffin tin with muffin liners.
In a large bowl, whisk together the mashed banana, pumpkin puree, melted butter, eggs, granulated sugar, brown sugar, and vanilla extract.
Add the flour, baking powder, baking soda, salt, and pumpkin spice. Whisk together before folding into the batter.
Mix just until well-combined (being careful not to over mix).
Fill each muffin cup 3/4 full with the batter.
In a small bowl, combine the turbinado sugar, melted butter, oats, and flour. Sprinkle the streusel topping over the muffins.
Bake for 20-25 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Let the muffins cool in the pan for 5 minutes before removing them to a wire rack to cool completely.
Notes
For extra moist muffins, use ripe bananas!
Be careful not to overmix the batter, as this can make the muffins tough.
If you don't have pumpkin spice, you can make your own by combining 1 teaspoon ground cinnamon, 1/2 teaspoon ground nutmeg, 1/4 teaspoon ground cloves, and 1/4 teaspoon ground ginger.
For a fun twist, add 1/2 cup of chocolate chips or chopped nuts to the batter!
