Preheat oven to 350F. Lightly grease a loaf pan with oil or butter/margarine or line with parchment paper.
In a large bowl, mash your bananas. Whisk in your milk, oil, vanilla and egg.
Add your dry ingredients to the wet mixture and mix all together. Don't overmix.
Transfer the mixture to your prepared loaf pan. Bake for 45 minutes or until cooked through. The bread should be firm on the outside, yet moist on the inside.
Let it cool 5-10 minutes before slicing.
