I chose this banana bread recipe from Simply Recipes because I had most of the ingredients. The recipe called for three or four ripe bananas. I only had two bananas, so I decided to improvise.
The recipe did not call for walnuts, but you cannot have banana nut bread without them. I was afraid they would dry out the bread, so I put the chopped walnuts on the top. This gave the nuts a slightly toasted taste.
