Direction's

1. Preheat oven to 350. Prepare a loaf pan . I used 8 by 4 but you can very well use 9 by 5. My preferred method is to grease the pan , line with baking paper and grease again. But you can butter the pan and dust it with flour also.
2. Mix bananas, butter, sugar, egg, and vanilla together . I use a small hand held cake mixer.
3. Sieve the flour along with baking soda and salt.
4. Then gently stir in flour in the banana mixture with light hand until well incorporated. 
5. Mix together the 1/3 cup sugar and 1 Tbs cinnamon kept for swirling.
6. Add half of the batter to the loaf pan and then sprinkle little more than half of the cinnamon-sugar mixture all over the batter in the pan. Add the rest of the batter, and then sprinkle the leftover cinnamon-sugar on top.
7. Bake for 50-60 minutes or until toothpick comes out clean.
