If you want to snazz up the loaf, slice a banana in half and set it on top of the loaf, cut-side up, before baking.
When you add flour to wet ingredients, be gentle. Stir just until the flour is incorporated. Overmixing the batter results in a tough loaf.
White sugar may be substituted for the brown sugar
