Best Banana Bread Ever, Seriously! - cooking recipe

Ingredients

1/2 cup butter
1 1/2 cups sugar
1 cup mashed banana (about 3)
1 egg
2 cups flour
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon salt
3/4 cup sour milk
1 teaspoon vanilla
2 teaspoons sugar
1/2 teaspoon cinnamon

Preparation

Cream butter, sugar, bananas and egg.
Mix all the dry ingredients together EXCEPT for the cinnamon and 2 tsp of sugar.
Add the dry ingredients alternatively with the sour milk. Try to end with dry ingredients. Add vanilla.
Preheat oven to 325.
Now -- heres the yummy trick- mix the cinnamon and 2 tsp sugar. Then grease the loaf pan and instead of dusting with flour, dust the pan with the cinnamon sugar mixture. Then pour in the batter and bake for 1-1.5 hours until a toothpick comes out clean when inserted in the middle.
Notes:
Sour milk is 3/4 cup of milk with one tablespoon of milk removed and replaced with one tablespoon of white vinegar.
I like to make my banana bread in a larger cake pan so it cooks faster.
