Preheat the oven to 375º Fahrenheit. Line 24 muffin cups with paper liners or spray with cooking spray.
In a large bowl, mix together the oil, sugars, eggs, vanilla, pumpkin and mashed banana. 1 cup vegetable oil , 1 ½ cups granulated sugar, ½ cup brown sugar, 2 large eggs, 2 teaspoons vanilla extract, 1 cup solid pack pumpkin puree, 1 1/4 cups mashed ripe banana
Add the flour, salt, baking soda, baking powder, cinnamon and pumpkin pie spice to the wet ingredients. Mix in the dry ingredients with a whisk until barely combined, then use a rubber spatula to fold together a couple more times until the batter is fully mixed. Do not overmix. 3 cups all-purpose flour, 1 teaspoon salt, 1 teaspoon baking soda, 2 teaspoons baking powder, 2 teaspoons cinnamon, 2 teaspoons pumpkin pie spice
Use a cookie scoop to scoop the batter into prepared muffin pans. Divide the batter to make 24 muffins.
Make the streusel. In a small bowl, use a fork to cut together the butter, sugar and cinnamon. Sprinkle the topping evenly over the muffin batter. Or sprinkle raw sugar over the tops of the muffins if you’d like a simpler topping. 2 tablespoons cold salted butter , 2/3 cup firmly packed brown sugar, 1 teaspoon ground cinnamonOR ½ cup raw sugar
Bake the muffins for 18 minutes, until the muffins have risen and a toothpick inserted in the center comes out clean or with a few moist crumbs.
