Step 1: Preheat your oven to 375 degrees. Lightly grease and flour a 10.5x15.5-inch jelly roll pan.
Step 2: In a large mixing bowl beat the sugar, sour cream, butter, and eggs with an electric mixer on medium speed until well blended, about 1 to 2 minutes.
Step 3: Beat in the bananas and vanilla on low speed until blended, another minute or so. Beat in the flour, salt, and baking soda on medium speed for 1 minute more.
Step 4: Spread the batter evenly into the prepared baking pan.
Step 5: Bake for 20 to 25 minutes or until a toothpick inserted in the center comes out clean and the bars are golden brown
Step 6: Remove from the oven and place the pan on a wire rack to cool completely. Once your banana bars have cooled you can sprinkle them with confectioners sugar or spread them with browned butter frosting.
Step 7: Cut into desired size bars - small, medium or super-sized - it's your choice. This recipe makes one 10.5 x 15.5-inch jelly roll pan of Sour Cream Banana Cookie Bars.
