In a large bowl mash bananas with sugar and vanilla until combined and creamy. Then mix in the water. (I just put these ingredients in my VitaMix Blender and it's much easier).
In a smaller bowl, sift together the flour, baking soda, baking powder and cinnamon.
Add the dry to wet and stir until just mixed . You don't want to over mix or the bread will be dry. (So important to stir just until mixed.).
Pour batter into sprayed loaf pan and bake in preheated 350 degree F oven for one hour. Your house will smell so good you will be temped to take it out a few minutes earlier but don't or it won't be done on the inside.
