Preheat oven to 350°F. Line a loaf pan with parchment paper and grease with cooking spray.
Mush bananas in a large bowl (with a spoon, fork, or mixer).
Add canola oil, sugars, and vanilla bean paste. Whisk thoroughly.
Add eggs and milk. Whisk until combined.
Add dry ingredients (flour, baking powder, baking soda, and salt). Mix with a spatula until just combined. Do not over-mix!
Fold in toasted nuts/chocolate chips.
Pour batter into prepared pan. Top with a sprinkle of sugar.
Bake for 60 minutes, checking for doneness by inserting a toothpick into the centre of the loaf. When done baking, the toothpick will come out with just a few crumbs stuck to it.
Let cool before wrapping or placing in an air tight container for storage.
