1In a large bowl, beat butter and sugar until crumbly, about 2 minutes. Add eggs; mix well. Beat in the bananas, sour cream, applesauce and vanilla. Combine the flour, baking soda and salt; add to butter mixture just until moistened. Fold in chips. Transfer to two 9-in. x 5-in. loaf pans coated with cooking spray.
2Bake at 350° for 40-45 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks
