Preheat oven to 350°F/180°C. Spray a loaf pan with nonstick cooking spray and set aside.
In a medium bowl, whisk together mashed banana, eggs, coconut oil, maple syrup, milk and vanilla extract.
In a large bowl, combine flour, baking powder, cinnamon and salt. Add wet ingredients to dry and stir with a spatula until just combined. Fold in blueberries, hempseeds and white chocolate chips.
Pour batter into prepared loaf pan. Bake 50 to 55 minutes, or until a toothpick inserted into the center comes out clean. Allow to cool 10 minutes before slicing.
Baking tip: If the top begins to brown before the center is fully baked, loosely tent the loaf with foil for the final 10-15 minutes.
