This is absolutely the best! The frosting with chunks of walnuts make it so good. I bake it in four small aluminium pans. Great to give as gifts. You will make this often. If you don't care for banana nut bread, try this one. It's more cake-like and this one will change your mind.
1Grease and flour pans. (2 loaf pans, or one 9x13 or you can use 4 of the small individual loaf pans). Beat butter till fluffy in large bowl with electric mixer. Gradually add sugar and continue beating until light and fluffy. Beat in eggs.....one at a time...add vanilla. Sift flour, baking powder, baking soda and salt together. Add to sugar mixture alternately wth sour cream. Fold in bananas and walnuts just until blended. Bake 325 degrees for 40 minutes or until done. Cool slightly in pans before removing. Frost tops and put chunks of walnuts down center.
