This recipe came from a friend. I can't remember when I had this cake last, but I remember enjoying it when I did. It tastes good with a plain white frosting or cream cheese frosting. I don't use box cake mixes any more, so I didn't post a picture of it since I haven't made it in a long time. But, it is a great recipe to use with ripe bananas.
2/3 cup water
1 Tbsp. Vinegar
1 1/4 cups very ripe bananas, mashed
1 pkg. White Cake mix
2/3 cup chopped walnuts
1 tsp. baking soda
Mix water vinegar and soda. Combine with cake mix and eggs. Add bananas. Beat w/ electric mixer at med. speed for 3 minutes. Blend in chopped nuts. Pour into greased and floured 9 x 13 pan. Bake at 350 for 35 minutes or until done. When cool, frost.
