Preheat oven to 165 degrees Celsius and line a loaf pan with greaseproof or baking paper.
In a large bowl, beat the oil and honey together with a whisk. Add the eggs and beat well, then whisk in the mashed bananas and milk.
Add the baking soda, vanilla, salt and cinnamon, and whisk to blend.
Lastly, switch to a big spoon and stir in the flour, just until combined. Some lumps are ok! If you’re adding any additional mix-ins, gently fold them in now.
Pour the batter into your loaf pan and sprinkle generously with cinnamon and a tablespoon of brown sugar.
Bake for 60 minutes, or until a toothpick inserted into the center comes out clean.Let the bread cool in the loaf pan for 5 minutes, then remove fro the tin and place on a wire rack to cool for 20 minutes before slicing.
