Using a fork, mash bananas in a bowl. You should have about 1 cup. In another bowl, sift together the flour, baking soda and salt. In a third bowl, using handheld mixer on high speed, beat together butter and sugar til light in color an texture, about 3 minutes. Gradually beat in eggs and then the mashed bananas. Reduce speed to low and add the flour mixture in 3 additions alternately with the sour cream in 2 additions, beginning and ending with flour mixture and stopping to scrape down bowl as needed. Beat til smooth. Fold in chocolate chips and half of the walnuts. Pour batter into prepared pan and smooth the top. Sprinkle remaining walnuts on top.
