Preheat oven to 350 and line a loaf pan with parchment paper. Always leave a bit hanging over the edge as it makes it easier to remove.
Next, place the mashed bananas in a bowl. Dump in the eggs, butter, brown sugar, maple syrup, vanilla, and mix to combine.
Add in the flour, baking powder, salt, and cinnamon and mix just until combined. The key here is not to over mix.
Pour banana mixture into the pan and top with the final banana, cut side up.
Bake for 1 hour or until you can poke with a skewer and it comes out clean. Allow to cool in the pan for 5 minutes and then remove totally and let cool fully on a rack. Now dive in!
