"Through several trials and errors, this is what I've come up with. I hope you enjoy as much as my family does."
bananas, overly ripened
eggs, slightly beaten
cream cheese, softened
In a large mixing bowl, cream together the sugar and butter. Add the mashed bananas; combining well. To this mixture, add the sour cream, eggs, vanilla, baking soda adn salt. Beat until well combined. Add the flour and nuts. Mixing to combine well.
Pour into prepared, greased and floured pan. Bake at 350 degrees. Depending on size of pan used; bake until a toothpick inserted in center comes out clean. You can bake this in any size or type pan. It's not a huge rising cake, so fill your pans accordingly.
To make the frosting, mix powdered sugar, banana, butter and cream cheese. Stir in vanilla and enough milk to make spreading consistency. Frost cooled banana cake.
This recipe can easily be doubled or tripled for larger quantity without trouble.
One note on the bananas for the cake portion -- the riper the better! I actually prefer that the bananas to be engrossly black for this recipe.
