Preheat oven to 350F and prepare a muffin pan with liners.
In a medium sized mixing bowl, combine flour, baking powder, baking soda, pumpkin pie spice, and salt.
In a separate large sized mixing bowl, mash bananas and stir in pumpkin puree, brown sugar, melted coconut oil, and dairy-free milk.
Fold dry ingredients into wet and mix until just combined. Gently stir in any add-ins, if using.
Fill the muffin tins ⅔ of the way, depending on your muffin pan you may get extra muffins.
Bake for 20 minutes or until golden brown, fluffy, and fully cooked.
Remove from oven let rest for 5 minutes, then flip out onto wire cooling rack to cool completely.
