Oh so good banana bread

i LOVE this recipe! it's easy, delicious and is a great use of extra ripe bananas. i'll post the original recipe but i'll put my alterations in parentheses. after making this, you'll never buy banana bread ever again! :)

ingredients:
1.5 cups of all purpose flour
1.5 teaspoons baking powder
1/4 teaspoon baking soda
1/8 teaspoon salt
1 egg
3 very ripe medium-sized bananas = 1 cup mashed
3/4 cup sugar (i usually put less, like 1/2 cup or less)
1/4 cup cooking oil (more oil will make it very cake-y & moist)
1/2 cup chopped walnuts

directions:
1) grease the bottom and sides of a 8x4x2 inch loaf pan - set aside.
2) in a medium mixing bowl, combine the flour, baking powder, baking soda, salt. make a well in the center of this dry mixture - set aside.
3) in another bowl, combine the egg, mashed bananas, sugar, cooking oil and walnuts. add this wet mixture all at once to the dry mixture. stir until moistened (batter should be lumpy).
4) spoon batter into prepared pan. cover the top of the batter with a thin layer of sugar! bake at 350F for 50-55 minutes or until toothpick or knife comes out clean from the center. let cool for 10 minutes. remove loaf from pan and let cool.
