I've baked these bars several times now and have finally taken same pics of them so I can share them with you! These are really more cakey than you would think. They are wonderful. I brought them to work the first time I made them and they were an instant hit! The frosting is so good. So good in fact that I got carried away and started eating it right out of the bowl, which is not good to do! Also, you can replace the sour cream wth some yogurt if you like. I didn't have sour cream on hand the second time I made this so I just used strawberry/banana yogurt and it came out fine. I found these over at Cafe Zupas. Delicious!
1/2 cup butter, softenend
1 1/2 cups white sugar
1 cup sour cream
1 teapsoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1/4 teaspoon salt
1 cup mashed ripe banana
Preheat over to 350 degrees F. Grease a 9 x 13 inch pan.
In a large bowl, cream together the butter and the sugar until smooth. Beat in the eggs, one at a time, then stir in the sour cream and vanilla. In a separate bowl, combine the flour, baking soda and salt; stir into the wet batter. Finally, mix in the mashed banana. Spread evenly into the prepared pan.
Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean. Allow the bars to cool completely before frosting.
