I made this cake because I needed to use overripe bananas and this was something new to try. It was amazing! It makes a ton so I delivered some to neighbors and friends, and every single one of those people came to me later and demanded the recipe. Its such a light, fluffy, delicious "cake". It was easy to make and the flavors are perfect together.
- For the banana bars, preheat the oven to 350 degrees. Grease a 10 x 15 inch jellyroll pan or one 9X13 pan and an additional 8X8 pan. In a large bowl, cream together the butter and sugar until smooth. Beat in the eggs, one at a time, then stir in the sour cream and vanilla. Combine the flour, baking soda and salt in a medium bowl; stir into the batter. Finally, mix in the mashed banana. Spread evenly into the prepared pan(s). Bake for 20 to 25 minutes, until a toothpick inserted into the center comes out clean. Allow bars to cool completely before frosting.
- For the frosting, in a large bowl combine cream cheese, sugar, salt and vanilla. Beat until light and fluffy. Set aside. In another medium bowl, beat whipped cream until stiff peaks form (it helps to use a chilled bowl and chilled beaters). Fold whipped cream into cream cheese mixture. Frost to your heart’s delight!
